Inaugural Professorial Lecture: Noah Cowan
May 14 @ 4:00 pm – 6:00 pm
Inaugural Professorial Lecture: Noah Cowan @ Mason Hall Auditorium

Noah Cowan will deliver a lecture as part of the Don P. Giddens Inaugural Professorial Lecture Series. Cowan is a professor in the Department of Mechanical Engineering.

Neuroscience in The Matrix

Understanding how the nervous system encodes and processes sensory information, transforms it into meaningful intermediate representations in the brain, and computes motor output involves decoding a complex closed-loop control system. Professor Cowan will present research devoted to developing and applying ideas in engineering to decode closed-loop neuromechanical control in animals, including humans.

The Don P. Giddens Inaugural Professorial Lecture Series began in 1993 as a way to honor newly promoted full professors. Professor Giddens, originator of the series, served as the fifth dean of Engineering at Johns Hopkins.

Fifth Frederick Jelinek Memorial Summer Workshop
Jun 25 – Aug 3 all-day

This is the fifth in a series of six-week-long research workshops on Machine Learning for Speech Language and Computer Vision Technology. These workshops bring together diverse “dream teams” of leading professionals, graduate students, and undergraduates, in a truly cooperative, intensive, and substantive effort to advance the state of the science.

These workshops constitute a continuation of the well known Johns Hopkins University summer workshops, and encompasses all areas of human language technology including automatic speech recognition, natural language processing, machine translation, topic detection and tracking, information retrieval and extraction, summarization and question answering, and certain related areas of computer vision, including image understanding and visual scene analysis. These fields share many important algorithmic and statistical approaches, allowing cross-fertilization. Machine learning challenges that arise from these areas are of fundamental scientific interest and are shared with many other fields of science and engineering, such as medical-/bio-informatics and social network analysis.

The primary goals of the workshop series are to advance basic science, attract students to the field and prepare them for research by putting them to work on exciting problems alongside senior researchers in a highly collaborative environment. Creation of research infrastructure and lasting collaborations are secondary goals.

Re-Envisioning Wastewater Treatment for the 21st Century

Abstract: The philosophy of municipal wastewater treatment has changed only slowly in the past 100 years. From approximately 1920 to 1970, a wastewater discharge was considered acceptable if the dissolved oxygen level in the receiving stream did not dip below 5 mg/L downstream of the discharge. Protecting aquatic life, particularly fish, from immediate death due to low oxygen levels was the primary motivation and the goal. The passage of the Clean Water Act in 1970 reflected a broader view to include concerns about eutrophication by nutrients and ecological and human health concerns with the naming of “priority pollutants.” Nevertheless, the central concept was that discharge concentrations would be acceptable if they took advantage of the assimilative capacity of receiving waters; that is, if they limited the harm to acceptable values. Now we are embarking on a new philosophy, captured by the phrase “One Water” by the Water Environment Federation, in which we think of wastewater not as a problem for disposal but as a resource.

Why is this shift in philosophy happening? At least two major changes have occurred since the old philosophies were developed. First, a dramatically increased population has led to a substantial increase in “indirect potable reuse” of wastewater, whereby the effluent discharge from one city is a part of the drinking water source for a downstream city. In many areas of the arid Southwest, that “part” can often be nearly 100%. An extension of this trend, due to water shortages, is the drive toward direct potable reuse of wastewater. Second, not only do the chemical and pharmaceutical industries now produce tens of thousands of synthetic chemicals that were not dreamed of when the “priority pollutant” list associated with the Clean Water Act was developed, we now understand that some of these products are endocrine disruptors and others lead to microbial antibiotic resistance.

In this talk, I will try to make the case that wastewater treatment needs to be changed, perhaps radically, to reflect the new philosophy and to meet the needs of the 21st century. The thrust of the presentation will be to explore some possibilities for these radical changes and try to back them up with preliminary engineering calculations.

Annual Billig-Croft Lecture (Fall 2018)
Nov 7 @ 2:00 pm – 3:00 pm


David M. Van Wie, PhD, will present “Hypersonics: Back to the Future.”

hypersonicsHypersonics: Back to the Future

Hypersonics is defined as flight at speeds above Mach 5—five times the local speed of sound. Currently, there is a resurgence of interest in hypersonic systems for applications such as weapons, rapid commercial transportation, and space launch. To realize these new applications, technology advancements are needed in the areas of novel thermal protection systems, high-temperature materials, advanced guidance, navigation and control, and propulsion. For more than 60 years, researchers at the Johns Hopkins University Applied Physics Laboratory have been investigating hypersonic technologies and applications, including Frederick S. Billig’s pioneering development of scramjet engine technology. Dr. Van Wie will offer a brief history of hypersonics highlighting Dr. Billig’s contributions and will discuss ongoing technology development challenges in this area.

2019 Ilene Busch-Vishniac Lecture – “From Hopkins BME to Columbia Surgeon: An Unexpected Journey”
Feb 27 @ 3:00 pm – 4:00 pm
2019 Ilene Busch-Vishniac Lecture - "From Hopkins BME to Columbia Surgeon: An Unexpected Journey" @ The Eisenhower Room (The Johns Hopkins Club)

Beth Schrope, MD, PhD, will deliver the 2019 Ilene Busch-Vishniac Lecture on Wednesday, Feb. 27.

Schrope, who is an associate professor of surgery at Columbia University Medical Center and an associate professor of clinical surgery at NewYork-Presbyterian, will detail an unlikely journey from Hopkins BME to Ivy League surgeon, with the purpose of demonstrating goal-directed living with the allowance for a more opportunistic approach to life and career.

Inaugural Professorial Lecture: Rachel Karchin
Apr 18 @ 4:00 pm – 5:00 pm
Inaugural Professorial Lecture: Rachel Karchin @ Mason Hall Auditorium

Rachel Karchin will deliver a lecture titled “Computational modeling of cancer precursor lesion evolution” as part of the Don P. Giddens Inaugural Professorial Lecture Series. Karchin is a professor in the Department of Biomedical Engineering.

Genome sequencing studies of tumor samples from large patient cohorts have provided convincing support for the somatic mutation theory of cancer, which posits that neoplasms result from mutational activation of oncogenes and mutational inactivation of tumor suppressor genes. Tumor cells originating from the same ancestral lineage form clonal populations, and the size and time-ordering of the clones can be modeled by hierarchical tree structures. In this lecture, Professor Karchin will discuss her research group’s reconstructions of precursor lesion evolution in high grade serous ovarian cancer and pancreatic adenocarcinoma.

The Don P. Giddens Inaugural Professorial Lecture Series began in 1993 as a way to honor newly promoted full professors. Professor Giddens, originator of the series, served as the fifth dean of Engineering at Johns Hopkins.
