W. Harry Feinstone Department of Molecular Microbiology and Immunology

Master of Health Science

The nine-month Master of Health Science Program (MHS) requires coursework, a scholarly, literature-based essay and a seminar presentation. MHS students must complete 64 credit hours during the four terms of the academic year. Required courses account for approximately half of that number.

MMI has introduced the Master of Health Sciences with a focus on biotechnology. This new focus area recognizes that some students seeking to expand their knowledge of immunology and infectious disease pathogenesis may seek to apply that knowledge in the biotechnology sphere. The MHS with a focus on biotechnology is an ideal fit for students whose career goals could include working:

This new focus area provides MHS students with laboratory experience to understand the tools of the biotechnology world and the opportunity to take a business course at Johns Hopkins Carey Business School. In addition, the program allows students to develop the understanding of microeconomic theory needed for navigating the biotechnology world.   

The biotech-focused MHS program also allows students to customize their courses based on their interests and career goals.    

Laboratory experience

-          An immersive laboratory rotation which provides a solid foundation for medical research and biotechnology positions  

A real-world business course  

A foundation in micro economics

A course that provides the background necessary to analyze the market potential of innovations in the biotechnology sphere.

MHS degree candidates work closely with Department faculty members and a faculty adviser who assists the student in exploring the literature and selecting a topic for the required essay. MHS students will present one seminar based on the essay topic.

For more detailed information about the MHS degree, please consult the Master’s Program Handbook.

The remaining credits are flexible and may be individualized based on the student’s interests and career aspirations. Students may take courses offered in MMI or in other departments within and outside of the School.

Credits may also be earned for Special Studies conducted one-on-one with Department faculty. Examples of courses taken by current and former MHS students include:

Previous graduates of the MMI masters' programs have gone on to pursue PhD or MD degrees at institutions including Johns Hopkins Bloomberg School of Public Health, Johns Hopkins School of Medicine, Harvard School of Public Health, Yale School of Medicine, Drexel University, Stanford University, Penn State University, Baylor College of Medicine, and the University of California system.

Our masters' program graduates have also successfully competed for research positions at the National Institutes of Health, various military research facilities, non-profit organizations and leading biotechnology companies.
