Dr. Case's primary research interests include vaccine design, generation of broadly cross-reactive immune responses, mucosal immunity, viral immunology, and emerging pathogens.

Dr. Chandra specializes in Mycobacterium tuberculosis pathogenesis, with a special focus on immunometabolism. In recent work, she characterized a novel relationship between macrophage fatty acid metabolism and antimycobacterial immunity.

Dr. Chang works in the Doering lab at WashU studying fungal pathogenesis. She joined the Division as an Instructor in Medicine in 2026 after completing the WashU Medicine Physician-Scientist Training Program, where she completed her internal medicine residency and ID fellowship. She will be attending on the general ID inpatient service, with a plan to eventually focus on invasive fungal infections.

Miguel A. Chavez, MD MSc is currently working with the BJH-Antimicrobial Stewardship program and the division of Hospital Medicine in the department of Internal Medicine as an Instructor.

Dr. Chong specializes in innate immunology and infectious diseases, with a special focus on how innate immunity responds to flavivirus infection. He is also very interested in identifying host factors of flaviviruses including West Nile virus, Dengue virus, Zika virus, etc. by using CRISPR screening.

Dr. Cunningham was born and raised in Scottsdale, AZ. He earned his PhD at the University of Missouri. He then completed his medical education at Mayo Clinic Alix School of Medicine and his residency at the Mayo Clinic Arizona before returning to Missouri for his ID fellowship at WashU Medicine. His areas of interest are transplant ID, medical education and invasive fungal infections. He is also an avid rock climber.

Why did you choose WashU for your ID fellowship?
“I chose WashU for the excellent training it offers across the full spectrum of infectious diseases, from bread-and-butter cases to unusual infections in severely immunocompromised patients. No matter what you want to pursue within ID, you will receive excellent support from program leadership.”

Dr. Curtis specializes in clinical infectious diseases, with a particular focus on diseases impacting pregnant people living with substance use disorders, such as HIV, hepatitis C, and syphilis.

Michael Diamond, MD, PhD is the leader of a basic and translational research laboratory studying the interface between viral pathogenesis and host immunity. His laboratory focuses on emerging RNA viruses including flaviviruses, alphaviruses, and coronaviruses.

Dr. Doiron has specialized in infectious diseases since 2004. She serves as a preceptor for nurse practitioner students and speaks at regional conferences on infectious disease issues.

Dr. Dubberke specializes in clinical and translational infectious diseases, with a focus on transplant infectious diseases, hospital epidemiology, and Clostridioides difficile infection (CDI).

Dr. Dunagan’s primary research focus is in the assessment and improvement of healthcare quality, with a particular emphasis on patient safety research, medical informatics and infection prevention.

Dr. Durkin uses administrative data to identify opportunities to improve antibiotic prescribing in outpatient settings, with a focus on outpatient and community settings; harnesses survey and qualitative research methods to identify potential solutions based on input from frontline providers; and designs, pilot tests, and disseminates antibiotic stewardship interventions using dissemination & implementation science and informatics technology.

Dr. Fabricant attends on the inpatient ID consult service at BJH. He runs a general clinic and also works with our HCV and STI programs.

Dr. Fernandez returns home to Missouri for her ID Fellowship. She grew up in the small southwest town of Verona, MO lived there until she moved to Columbia University in New York City to earn her BA. Dr. Fernandez completed her MPH at Emory University, Rollins School of Public Health and medical school at the University of Missouri in Columbia, before completing her Internal Medicine residency at the University of Southern California (USC) in Los Angeles, California in 2026.

Dr. Fernandez is interested in the intersection of public health and infectious diseases, including the prevention and treatment efforts of tuberculosis, tropical diseases and chronic hepatitis.

Why did you choose WashU for your ID fellowship?

“Returning to the Midwest was a priority. During interview day, WashU ID stood out as a top program with a wide reach within the Midwest region. This reach allows for exposure to diverse clinical cases, all while providing ample opportunities to work within the public health sphere.”

Dr. Fischer specializes in basic and translational sciences to support the control and elimination of neglected tropical diseases, with a special focus on helminths.

Dr. Fleckenstein’s lab focuses on the identification and molecular characterization of novel ETEC virulence factors that could serve as targets for vaccine development. Studies in the lab use a variety of molecular techniques and in vitro and in vivo models to elucidate the role of these novel virulence factors in several key steps essential in the pathogenesis of these organisms: bacterial adhesion, intestinal colonization, and finally toxin delivery.
