The objective of the department’s Ph.D. program is to produce graduates who are broadly educated in  Applied Mathematics and Statistics and who can work at the current research frontiers of their specialized disciplines. 

A student should demonstrate mathematical comprehension in two stages:

  • general mathematical proficiency (breadth), measured by an Introductory Exam on the following topics: real analysis, linear algebra, and probability; and
  • qualification for advanced research (depth), measured by The Graduate Board Oral Exam covering in-depth knowledge of the student’s proposed research area.

A key objective is to enable those students with the desire and background to do so, to get an earlier start on initial research-type activities.  These activities would not necessarily be in the same area as the ultimate doctoral research, and typically would not have the same degree of intensity and commitment as that later work; for example they would involve interaction with the student’s faculty “mentor” rather than an official “dissertation advisor.”  One role of the Introductory Exam is to gauge preparation for such activity.

The current University Catalog contains a detailed description of the department’s courses, programs, and requirements and a list of the current faculty and their interests.  The purpose of this handbook is to present supplemental information; it should be read along with the departmental listing in the Catalog.

The student must accomplish the following to obtain departmental certification for the Ph.D.  More detailed information on these items is provided in the following sections.

  1. Pass the Introductory Examination by the end of the second semester.
  2. Find a research advisor and begin mentored research by the end of the fourth semester. Failure to do so will result in academic probation.
  3. Pass the Graduate Board Oral Examination before the start of the student’s seventh semester. The scope of the exam will be governed by a syllabus prepared by the student with the help of the student’s mentor or advisor.
  4. Acquire and hone their teaching and research experience under the supervision of faculty by successfully completing either a TA or RA assignment every semester while a full-time, resident student.  See section below for further information on the teaching requirement.
  5. Complete at least 8 one-semester courses of graduate work in a coherent program approved by the faculty advisor. Additional details may be found in the Course Program section of this handbook. 
  6. Demonstrate a working knowledge of the utilization of computers in Applied Mathematics and Statistics.  This is typically done by completing a course with a grade of B- or better from a list of courses, which can be viewed in the Information for Computing Certification section below. 
  7. Complete a program of original research and its clear exposition in a written dissertation.  The dissertation must be approved by at least two faculty readers and be certified by them to be a significant contribution to knowledge and worthy of publication.  The candidate must then defend the dissertation in a public examination held under the auspices of the Department.
  8. All requirements for the Ph.D. in Applied Mathematics and Statistics must be completed  within 9 years from the date the student entered the Ph.D. program.  A student who does not complete the degree requirements in 9 years will be terminated from the program due to unsatisfactory progress.

In addition, the student must fulfill the following university and WSE requirements.

  1. A minimum of two consecutive semesters of registration as a full-time resident graduate student
  2. Complete training in academic ethics
  3. Complete training in the responsible conduct of research

The most common way for students to gain the knowledge and skills to succeed in the Ph.D. program is through coursework.  The relevant courses for the Ph.D. are of two types

  • basic graduate-level courses;
  • additional specialized courses appropriate to the student’s field of research.

Basic Courses:  All students are encouraged to master basic material in:

  • probability (553.720), statistics (553.730), or stochastic processes (553.626)
  • optimization (553.761, 553.762)
  • numerical and matrix analysis (553.781, 553.792), and
  • discrete mathematics (553.671, 553.672).

Normally, a student will have completed at least eight basic courses by the end of the fourth semester of residence.

Specialized Courses:  Each student takes advanced courses appropriate to the proposed area of dissertation research.

COURSELOAD REQUIREMENTS

Students must complete, with grades of B- or better (or equivalent level of performance in “pass-fail courses”) at least 8 one-semester courses of graduate work in a coherent program approved by the faculty advisor.  All 600-level and 700-level courses (with the exception of seminar and research courses) are satisfactory for this requirement.  Certain courses in other departments are also acceptable, and must be approved by the student’s advisor in advance.  WSE/KSAS courses listed as 2-credit courses count only as one-half course.  SPH courses count only as one-half course.  The 8-courses requirement is a minimum and students are encouraged to take courses throughout the duration of the program. Students who enter the PhD program after completing a Master’s degree may be permitted to count up to two courses taken during their Master’s program toward this requirement.  A student’s advisor will consider requests for approval and notify academic staff accordingly.

Students should take a combination of course(s) and 553.800 Dissertation Research each semester which when combined with course credit hours, will total at least 20 credit hours per term.

Students must also register for and attend the weekly department seminar 553.801.01.

(Students enrolled part-time may have different registration requirements and should seek guidance from the academic program staff and their faculty advisor.)

In consultation with his or her advisor, each student will develop a program of proposed coursework.  This program should not be thought of as a firm contract but as a basis for planning; typically it will need to be updated from time to time.

IMPORTANCE OF COMPUTER LITERACY AND COMPUTING COMPETENCE

Familiarity with computing is essential to applied mathematics, and students should aim for practical problem-solving capability for computing in applied mathematics.  Thus, every department graduate should possess a working knowledge of the utilization of computers and the fundamentals of scientific computing.  This includes, but is not limited to, such topics as: computer programming (e.g., FORTRAN or C++), numerical software packages (e.g., MATLAB), symbolic computations (e.g., MAPLE), technical word processing (e.g., LaTeX), and professional presentation (e.g., PowerPoint).

The requirement below is a minimal one, aimed at ensuring that students demonstrate some ability at using the computer for problem-solving through homework assignments and projects.

TIMETABLE

It is expected that students discuss their plans to meet this requirement with their faculty advisors.  As early as possible, students and advisors should agree on a program of work whose satisfactory completion would meet the computing requirement.  Students with no previous background in computing should first acquire basic competence during their first year of residence, either by independent study, or by participation in an elementary course.  It is recommended that students meet this computing requirement within their first year of residence, and certainly no later than six months before graduation.

CERTIFICATION

Students meet this requirement typically by receiving a grade of B- or better in an approved course.

The list of approved courses together with the years in which versions of these courses can be used to meet the requirement is:

  • 110.445 Mathematical and Computational Foundations of Data Science
  • 553.600 Mathematical Modeling and Consulting
  • 553.613 Applied Statistics and Data Analysis

The Introductory Exam is a written exam and tests for an understanding of the basic areas listed below, and for general proof-writing and integrative skills. This exam is designed to be taken and passed early in a student’s graduate academic career.

A student is required to pass the exam by the end of their second semester in the Ph.D. program. In anticipation of the possibility of not passing the exam and departure from the Ph.D. program, interested students are also advised to plan for completion of the Master’s degree requirements. 

SCOPE

The Introductory Exam will consist of three separate exams in linear algebra, real analysis, and probability.  Students must pass (with standard set by a faculty committee) the final exams in three courses, 553.701 (real analysis), 553.792 (linear algebra), and 553.620 (probability.)  Students will also have the option the August before beginning the program, to pass the exams without taking the courses.  (Students beginning the Ph.D. program in the spring semester will have the opportunity to take the August exam after their first semester.)  All three exams (real analysis, linear algebra, and probability) must be passed to pass the Introductory Exam.

Syllabi for these topics are given on this page:  Introductory Exam Syllabus

GRADING

Clear thinking and writing are important on the Introductory Exam, and the student’s grade will reflect this. Each student’s course final exam will be graded by the course instructor for the course itself, and a departmental committee will determine whether the student’s work is of sufficiently high quality to merit passing the Introductory Exam requirement in that specific area.

Click here for Past Introductory Exams with Solutions 

Students must have a supervisory committee created by the end of their 5th semester. Failure to do so will result in academic probation. 

 The supervisory committee will consist of the thesis advisor and two other members recommended by the advisor, and is charged with overseeing the student’s research progress until the completion of his/her doctoral study.  In most cases, a student’s supervisory committee will consist entirely of AMS faculty members.  In exceptional cases, as appropriate, non-AMS faculty may be approved by the Director of Graduate Studies. 

 Ideally, the membership of the student’s supervisory committee shall remain unchanged until his/her dissertation research is completed; however, it may be reconstituted if necessary. 

 The supervisory committee will review and evaluate the student’s performance each semester, with a formal written evaluation annually.  

To request approval of the supervisory committee, a student should contact academic program staff with a list of the proposed members (copying your research advisor.)  Academic program staff will contact the proposed members to determine willingness to serve, and finalize the committee.

 

No later than two months before the beginning of the student’s seventh semester, the student should start the process to schedule the Graduate Board Oral Examination.  (Faculty from other departments, perhaps corresponding to the student’s elective courses, will be among the examiners.)

Additional information about the Graduate Board Oral Exam can be found here.

SCOPE

The examination panel will evaluate the student’s preparedness and potential to carry out the proposed research program.  The rules of the Graduate Board state that the purpose of the examination is “to test the depth and breadth of the student’s knowledge and reasoning abilities”, and that the scope of the examination is not to be sharply defined but rather is to be set by the examination committee on the basis of the student’s course record and the specific departmental requirements.

The scope of the exam for AMS Ph.D. students will be governed by a syllabus prepared by the student with the help of the student’s mentor or advisor. The syllabus should offer several general areas related to the student’s proposed area of research along with a specific research topic on which the student will be examined in even greater depth.  This syllabus may include a thesis proposal in which case its presentation would be part of the exam. 

Students may view examples of past students’ syllabi, for reference only.

MECHANICS

The Graduate Board Oral Examination Committee is comprised of three members from within the AMS Department (suggested to be members of the student’s supervisory committee) and two members outside of the AMS Department. Graduate Board policy requires that committee members be selected by the Department Chair.

A Ph.D. candidate’s program of original research and the written dissertation to which it leads are the highlight and culmination of doctoral study.  The dissertation is the written documentation of the findings of the research program, and is required by the University to constitute a “significant contribution to knowledge worthy of publication in scholarly journals.”  Not only the research but also the exposition, grammar, and style must be of the highest order.

The dissertation defense is a public presentation and discussion of the findings of the research program, conducted before a committee of members of the faculty (not necessarily all from this department).  It is open to attendance by all members of the University community.  The dissertation defense is the climax of the Ph.D. program.

The following procedures are consistent with this interpretation of dissertation research, manuscript, and defense.

  1. Dissertations must be prepared in accordance with University requirements; a detailed statement of these is available at http://guides.library.jhu.edu/etd.
  2. The University requires that two Readers study the dissertation carefully and sign a letter attesting that it is indeed a “significant contribution … “.  The “First Reader” is, of course, the research advisor, while the “Second Reader” is usually another member of the department, chosen by you and your advisor, with research interests closely related to yours.  Second Readers may, if appropriate, be chosen from other departments or even, in exceptional cases, from outside the University.  Early selection and involvement of the Second Reader can lead to significant improvements in the dissertation.  The Readers’ Report, signed by both Readers, must be available to the examining panel members two weeks in advance of the defense.
  3. The defense must be held at least two weeks before the Graduate Board deadline to be met, in order to allow time to make any changes in the dissertation that are required by the defense panel.
  4. Before the defense will be scheduled, all other departmental and university requirements for the degree must be fulfilled.
  5. At least three weeks before the desired date of the defense, the candidate must start the process to schedule the defense.  The defense panel should include the Readers, plus two or three faculty from within or outside the department.  Click here to access the form to begin the dissertation scheduling process.  The student should distribute copies of their dissertation to the defense panel members, and an electronic copy should be given to the academic program staff, who will make it available by request for examination by department faculty and graduate students.  The dissertation as defended must be complete:  Only changes required by the defense panel should be made following the defense.
  6. One official University copy of the dissertation is required by the Graduate Board and must be submitted electronically, via the JHU ETD portal. https://etd.library.jhu.edu/. Students are expected to submit their final approved dissertation within one month of their successful defense, but may petition for additional time.
  7. After the dissertation has been defended and the University copy submitted via the JHU ETD portal, the candidate must email the following items to the WSE Director of Graduate Affairs ([email protected]) and copy the department Academic Program Coordinator. a) the ETD submission approval email  b) the title of the candidate’s dissertation typed in the body of the email (with correct spelling and punctuation.)
READERS’ REPORTS AND CHECKLIST
REQUIREMENTS FOR SUBMITTING A READERS’ REPORT

A Readers’ Report must be received for all students receiving a Ph.D., or a Master’s Degree with essay.

Dissertation Readers are to be selected and appointed by the sponsoring department or committee.  Any duly appointed member of a department or committee sponsoring Ph.D. candidates and holding the rank of assistant professor or higher (including visiting professors, but excluding lecturers) is eligible for selection as a Reader without prior approval.  Readers from outside the University structure, or from any non-Ph.D. sponsoring department, laboratory, or institute within the University, must be approved by the Graduate Board Office.  Such approval will be forthcoming only when such an appointment is justified in writing by the chair of the department or committee making the request.

Two Readers are required for Ph.D. students and one for Master’s students.

Readers’ Reports, in order to qualify for acceptance by the Graduate Board, must certify that the dissertation is a significant contribution to knowledge worthy of publication in its present form or with appropriate modifications, and that it is worthy of acceptance in partial fulfillment of requirements for the Ph.D. degree.  Readers’ Reports must show the academic rank or title of each Reader and the department and school (or University) with which he or she is associated.  The report must also be dated, give the student’s full name, and give the full title of the dissertation or essay.  The title must be correct since the transcript and graduation program show this title.

This report must be in the Graduate Board Office by the deadline date for that period and the date must precede the date of the departmental certification.

ADVISING

The primary source of advice and counseling about a student’s progress is the faculty advisor.

When a student first enters the department, the student is assigned (even before passing the Introductory Exam) an academic advisor.  The academic advisor assists the student in selecting courses and other administrative tasks, and provides general career guidance.

After a student has passed the Introductory Exam, the student is assigned a mentor.  The mentor is chosen in an area in which the student is proficient (and, it is hoped, interested).  The purpose of the mentor is to guide the student in choosing a research area.  The mentor does this by giving the student papers and other material to increase the student’s depth.  The mentor suggests depth courses.  The mentor may offer or make the student aware of research opportunities.  The mentor may guide the student to faculty who share the student’s research interest.  The mentor may eventually become the student’s dissertation advisor, but this is not a certainty.

Students are expected to find a research advisor and begin mentored research by the end of their fourth semester. Any full-time PhD student who has failed to do so will be placed on probation and, if this requirement is not met by the end of the probationary semester, will ordinarily be terminated from the program. Only in exceptional circumstances will petitions be considered to extend the probation. PhD students registered part-time are subject to a similar requirement to find a research advisor in a timely fashion.

Of course, a student’s research guidance need not come only from the research advisor.  The entire faculty of the department, indeed of the whole University, is available to each student to provide advice and assistance.

Policy on Mentoring Commitments for PhD Students and Faculty Advisors 

EVALUATION

The department conducts regular reviews of all graduate students, and notifies each student in writing annually (usually in early February) of his or her status.

At the end of each academic semester, faculty instructors for each of a student’s courses (even those outside the department) are asked to complete a written evaluation of the student’s performance.  If a student is a teaching assistant, the supervising faculty member is asked for a written performance evaluation also.

At the annual graduate student evaluation meeting, the faculty considers each student’s grades, written evaluations, passage of Introductory, Candidacy and Graduate Board Examinations, satisfaction of the computing requirement, research progress, and departmental citizenship.  The evaluation letter characterizes the student’s progress, provides advice, and states the faculty’s expectations for the student’s performance during the following year.

A full-time Ph.D. student who fails, in a given semester before passing their Introductory Exam, to receive a grade of B- or better in at least two courses in the program will be placed on Academic Probation. For a full-time Ph.D. student on Academic Probation, failure to pass at least two courses with a B- or better in any semester in the program is grounds for dismissal. Also, in any given semester, whether or not a student is on Academic Probation, they may be dismissed if they do not receive any grades of B- or better in their program.

All full-time PhD students are required to maintain funding status as either a teaching assistant, research assistant or externally-funded fellow during the program (with possible waivers only in exceptional circumstances). Although students are usually offered teaching assistant status with a specified period, loss of this status may occur at any time, even during the specified period, due to unsatisfactory performance. Loss of status will always be preceded by a warning to the student concerning their performance and will usually result in a one-semester probationary period, but egregious misbehavior may lead to immediate termination. Students who lose their teaching assistant status without finding a research assistant position will be terminated from the program.

Policy on Annual Academic and Professional Development Discussions for PhD Students and Their Faculty Advisor

MASTER’S PROGRAMS

Though enrolled in the PhD program, students should take steps to ensure that, if for whatever reason they are unsuccessful in their attempt to earn a PhD degree, they may still have something to show for the effort they have put in. To this end, students are advised to pay close attention to the department’s MSE requirements, and take steps to earn a Master’s degree as they pursue the PhD. Such a degree can be important for a student’s future career.

Students in the Applied Mathematics and Statistics PhD program may also apply to the AMS Financial Mathematics Master’s program or the AMS Data Science Master’s program.

Some of the department’s graduates will enter academic professions where formal teaching is part of their responsibility, while others will embark upon consulting, governmental, or business careers and do no formal teaching at all.  Every graduate will, however, have to “teach” in the sense that his or her ideas will have to be imparted to others.  By itself, this would suggest that some formal teaching experience is valuable for every graduate, but there is another reason as well.  Everyone who has ever taught anything has learned something; the very act of organizing information for someone else’s benefit helps one to understand it better.  This is particularly valuable for a graduate student trying to organize a body of knowledge for self benefit.  Finally, prospective academic employers usually request recommendations which evaluate the student’s promise for teaching as well as for research, and it is helpful to have some teaching performance upon which to base such recommendations.  For these reasons the department requires some supervised teaching experience for each student. This requirement may be fulfilled either by leading a discussion class in section or by being the instructor of record in an intersession, summer or academic year course.

Teaching Fellows Program

The Department Seminar meets weekly for the presentation and discussion of current research work.  Both University scholars and invited guests appear, and a wide variety of topics is covered in the course of a year.  All resident department graduate students are required to register every semester and to attend.

FULL-SUPPORT COMMITMENTS

The Applied Mathematics and Statistics Department makes a long-term full-support commitment to Ph.D. students. Per WSE policy, AMS Ph.D. students are fully funded (tuition, health insurance and stipend) for the duration of their Ph.D. program while they are in a full-time resident status.

As a part of the Ph.D. educational program, full-time Ph.D. students will receive an assignment as a Teaching Assistant or Research Assistant each semester.

Teaching Assistants provide teaching and grading assistance and are expected to spend up to 15 hours per week for 15 weeks per semester. All TAs with full-support commitments receive the same level of funding as any other fulltime, resident Ph.D. student, regardless of financial need or varying assignments.

Research Assistants work with individual faculty members who have research grants or contracts. The selection of RAs is made by the faculty member providing the funds, subject to approval by the Department Head. All RAs with full-support commitments spend up to 15 hours per week for 15 weeks per semester on assigned research and receive the same level of funding as any other fulltime, resident Ph.D. student, regardless of financial need or varying assignments.

Finally, some students may be supported 50% as RAs and 50% as TAs, with the teaching assignment reduced by half to help balance the time commitment.

Outstanding eligible candidates may be nominated by the Department for certain diversity-focused Fellowships awarded competitively by the Engineering School. These also carry a full-support commitment.

OBLIGATIONS OF FULLY SUPPORTED STUDENTS

Fulltime resident PhD students are expected to successfully complete at least twelve graduate courses before the completion of their degree, pass the various examinations required in the program, and start working with an advisor on research in a timely manner.

During the summer months, students remain expected to make academic progress based upon their stage in the Ph.D. program.  With advance approval, students may also temporarily disengage from their Ph.D. studies to participate in outside internships.

  • Students who have not passed the Introductory Exam are expected to use the summer to primarily study for the Introductory Exam, as well as take AS.360.625 (unless already completed.)
  • Students who have recently passed the Introductory Exam and have not identified a potential research advisor are expected to find a faculty member (who could be outside of AMS) with whom they will do research.  Research in this stage can be reading background materials, books, or articles about topics with the aim of trying to find a potential dissertation area.  Expectations will be set by that faculty member and reported to the Director of Graduate Studies.  Students must take AS.360.625 (unless already completed).
  • Students who have identified a research advisor or potential research advisor are expected to continue their research and prepare for the next step in their program requirements.  They are also expected to take AS.360.625 (unless already completed.)

Fully supported Ph.D. students are provided with a sufficient stipend to support their living expenses and allow them to devote fulltime effort to their studies. The department reserves the right to adjust/reduce internal support to a student so as to account for any external funding. There also may be academic/research performance ramifications to a student found to not be making satisfactory progress and also in violation of the above stipulations.

All students supported as TAs are expected to satisfactorily complete their teaching duties as directed by the course instructors. If needed, they are also expected to make appropriate efforts to enhance their language and communication skills so as to be the most effective teacher possible, which may require participating in training and improvement courses offered by the university.

Doctoral guaranteed funding is contingent upon maintaining satisfactory academic progress and includes an average of 5 hours/week of assigned work that contributes to the functioning of the PhD’s lab/group/academic department (including tasks such as ordering supplies, training other lab personnel, updating websites, maintaining equipment, assisting with recruitment activities, etc.), in addition to the student’s own academic research, and may include up to 15 hours/week of assigned work that contributes to the academic mission of the department, WSE, and/or university at large (for example, TA, RA, etc.) Consistent with the Collective Bargaining Agreement, students requesting remote/hybrid work, from a location within the United States, must submit a written proposal to the appropriate supervisor(s).

Contributing to maintaining satisfactory academic progress, full-time resident students are expected to remain engaged on campus except for holidays and periods of leave described in Articles 23 and 24 of the Collective Bargaining Agreement.  Note that this expectation includes any periods where classes may not be in session but the university is open, such as intersession, spring break, summer terms, fall break, etc.  Students are expected to actively work on fulfilling the requirements for their degree and remain engaged in their academic/research activities (which can include preparing for exams, academic research, taking courses, preparing research proposals, preparing their dissertation, meeting with academic advisors, attending seminars, etc.). Students are also expected to complete any work assignments, which are likely to require presence on campus.

Applied Mathematics and Statistics graduates elect one or two graduate student representatives each Spring semester.  The representatives attend all department faculty meetings (except where confidential matters are discussed) to provide the students’ point of view on issues being discussed.  The representatives also provide a means for other students to raise issues, voice concerns, or propose changes anonymously.

The Milton S. Eisenhower Library has extensive resources of books and journals and can draw freely on large nearby collections such as the Library of Congress. 

The facilities of the University Computing Center are available to all students for research and instruction.  

Resident full‑time Ph.D. candidates have access to shared office space in Wyman Park.

PURPOSE

The computing resources of the Johns Hopkins University Department of Applied Mathematics and Statistics exist to meet the computing needs of the Department’s faculty and graduate students for the purposes of instruction and research, and to provide access to relevant information and services of the Internet computer network.

ADMINISTRATION

We distinguish between operation (otherwise known as system management or administration) and administrative oversight.  Operation is considered to consist of those tasks related to the maintenance of software, hardware, user accounts, and any other tasks which directly affect the status and performance of the physical resources.  Administrative oversight will consist of the establishment and maintenance of software licenses, procurement of equipment, establishment of policies, and all other tasks not related to operation.

The computing resources of the Department are to be operated by one or more designated graduate Computer Assistants, possibly in collaboration with members of the faculty.  The administrative oversight of the computing resources is the responsibility of the Departmental Research and Facilities Committee.

AVAILABILITY

The computing resources of the Department will be available to those who are eligible for accounts on the Departmental server(s), as described below, for tasks consistent with the conditions of usage described under Acceptable Usage below.

All faculty, staff, and graduate students of the Department are eligible for computer accounts on the Departmental server(s).  Accounts for faculty and graduate student users will be maintained through the end of the first full semester after the user’s departure.  Accounts for staff members will be maintained at the discretion of the Research and Facilities Committee after the staff member’s departure

Undergraduate students, students from other departments, and former students from the Department of Applied Mathematics and Statistics, or any other person not specifically eligible as per above may obtain accounts or extend accounts past the normal termination date, as follows.  The requester must have the sponsorship of a member of the Departmental faculty.  The sponsoring faculty member should present the request to the Research and Facilities Committee and Department Chair for approval, whereupon the operator(s) will be instructed to create or maintain the account as specified.

If resource quotas are enforced, those users with accounts under special dispensation as described above may be required to observe resource limits different from those of eligible Departmental users.

The Department Chair is ultimately responsible for all decisions to create or terminate accounts on the Department’s server(s).  The Research and Facilities Committee recommends actions on these matters to the Department Chair.  Users will be notified by e‑mail two weeks prior to termination, in order to have time to properly clean out the account.

ACCEPTABLE USAGE

The users of the Department’s computing resources are responsible for adhering to all Johns Hopkins usage requirements, as well as all local, state, federal, and international laws.

Users are expected to observe the following:

1. General

  • Accounts are issued on a person-by-person basis.  Allowing anyone else to access an account is therefore prohibited, and repeated offenses may result in termination of the user’s account.
  • Accounts accessing, altering, duplicating, or deleting any data belonging to other users without that user’s consent is prohibited.  This includes, but is not limited to, so affecting system data files maintained by the Operator(s), such as system quota databases or password files.
  • Any unauthorized and deliberate action which results in the damage or disruption of a computer system is a violation of Acceptable Usage, regardless of the location of the affected system.

 2. Publication (mail and Web usage)

  • Any attempt to forge the source or sender of any network traffic, including but not limited to electronic mail, Web documents, or USENET articles, is prohibited.
  • Any attempt to read, write, alter, or delete another user’s electronic mail, USENET articles, etc., is prohibited.
  • Sending harassing, obscene, or threatening electronic mail, USENET articles, etc., is prohibited.  This includes the sending of electronic “chain letters”.
  • Using network or computer facilities for any commercial or for‑profit purpose is prohibited.  This
    includes, but is not limited to, e‑mail advertisements, professional correspondence that is not
    Department-related, and the inclusion of commercial advertising on Web pages.

3. Network security

  • Attempt to gain unauthorized access to any computers or networks (Departmental or otherwise) is forbidden.
  • Copying of copyrighted materials without permission is not allowed.

The reasons for these restrictions should be clear.  Further information and suggestions are available online.  Interested users may, for example, consult the Netiquette guide on the World Wide Web.
