Scholarship in the Division of Infectious Diseases
The Infectious Diseases division is active in multiple aspects of clinical and basic science research and is highly productive in this area. Division members have received continuous NIH funding for over a decade and laboratories provide a training ground for Infectious Diseases fellows and postdoctoral, graduate, and undergraduate students. Research interests within the division include:
●immunopathogenesis of hepatitis C infection
●epidemiologic studies in HIV infection
●vaccine trials in HIV infection
●molecular studies of HIV pathogenesis
●investigator-initiated clinical trials of antimicrobials
In addition, division members are involved in areas of scholarship that include quality improvement, patient outcomes research, and dissemination of clinical findings. Division members comprise the key editors and authors of the most recent edition of Gantz’s Manual of Clinical Problems in Infectious Diseases, a compendium of Infectious Diseases clinical knowledge.
