Data Science Master’s Program



The Data Science Master’s degree at the Johns Hopkins University will provide the training in applied mathematics, statistics and computer science to serve as the basis for an understanding, and appreciation, of existing data science tools.  Our program aims to produce the next generation of leaders in data science by emphasizing mastery of the skills needed to translate real-world data-driven problems in mathematical ones, and then solving these problems by using a diverse collection of scientific tools.



In addition to Introduction to Data Science (EN.553.636), students will take one course in each of the four core areas:  Statistics, Machine Learning, Optimization, and Computing.  Students will decide on an area of focus and take three courses in either Computational Medicine, Computational Machine Learning, Computer Vision, Computational Finance, Mathematics of Data Science, Language and Speech, or Statistical Theory.  The final capstone project is course EN.553.806 Big Data Design, or another project-oriented course approved by the faculty advisor and the Internal Oversight Committee, and a written paper on a related topic (approved by the instructor) which includes a deeper study of the pre-approved topic.  The goal of the final course and written paper is to allow the student to apply data analysis techniques learned in the program, and possibly to extend those ideas to more general settings or to new application areas.  Lastly, the paper will be summarized in a poster session organized at the end of each semester.


A course grade of B- or higher is required to meet all course requirements.
