COVID-19 Update


The Division of Infectious Diseases is committed to training our faculty, staff, and the next generation of leaders in infectious diseases through fellowships, global health education, specialized training, and continuing medical education. We often work in partnership with other Divisions, Departments, and Programs to offer comprehensive educational opportunities.

Infectious Diseases Fellowships

We offer ACGME accredited and ACGME equivalent fellowship programs for postdoctoral fellows, with an emphasis on research and clinical training. Both domestic and international students with the appropriate credentials are accepted into our fellowship programs. Candidates are encouraged to explore our websites for additional information.


Our commitment to our fellows is underscored by their success rates in pursuit of NIH Mentored Research Career Development (“K”) Awards. Building upon a legacy of successfully launched research careers, 95% (19/20) of our fellows' K applications have been awarded since Dr. David Thomas was named division director in 2005. Through semi-annual meetings of our research review committee and a cadre of dedicated faculty mentors, we help foster the professional growth of our exceptional fellows.


Our fellows are able to avail themselves with tremendous resources both within and outside our division. Within the division, there are 77 full-time infectious diseases faculty members, including 39 women. These faculty bring in in $30,688,407 in NIH-supported research funds annually -- more than any other division within the Johns Hopkins DOM. And that doesn't include many other potential mentors within the Bloomberg School of Public Health, its Department of Molecular Microbiology and Immunology, and other schools at our institution.

Charitable Giving

While many of the investigators in the Division of Infectious Diseases receive grant funding for their research, there are other critical activities that rely primarily on private donations. Individual support is essential to innovative research, training the next generation, and promoting the highest standards of clinical care.
