Dr. Jenny Hyde leads and performs basic research centered on virus-host interactions. Her work combines molecular virology and RNA biology to uncover the mechanisms by which viral RNA structures regulate RNA-protein interactions, with the goal of identifying new therapeutic targets and advancing antiviral and vaccine development.

Dr. Ingle is a virologist and functional genomics scientist who focuses on viral pathogenesis and host immune response.

Dr. Istvan specializes in the biochemistry of Plasmodium falciparum, the most deadly malaria parasites of humans.

A passionate advocate for health equity and sustainability, Dr. Iwelunmor is widely regarded for understanding how to make evidence-based interventions last, reshaping the focus on community engagement using participatory research, improving the dissemination of health information, while amplifying the voices of young people in health interventions.

Dr. Kepko is Assistant Professor of Medicine and serves as the Medical Director of Infection Prevention for Barnes-Jewish St Peters Hospital.

Dr. Kisaka specializes in cell, structural and molecular microbiology and currently works in the Kyei Lab.

Dr. Josh Klinnert hails from Amarillo, TX. He earned his Doctorate of Osteopathic Medicine at Kansas City University and before going on to complete residency at the University of Texas Medical Branch in 2026. Dr. Klinnert's clinical interests include tropical medicine, HIV, and phage therapy.

Due to prior experience working in a greenhouse, Dr. Klinnert really enjoys visiting the Missouri Botanical Garden. He also thrives on French bakeries, so you may find him drinking coffee at La Belle Vie.

Why did you choose WashU Medicine for your ID fellowship?
"I chose WashU for fellowship because of the diverse array of clinical infectious disease. As a major referral center for the Midwest, there’s a unique opportunity to see the intersection of urban and rural pathology which provides a truly comprehensive training experience. Additionally, the support offered by the program and the regard for fellow wellness is unparalleled."

Dr. Justin Klucher grew up in North Little Rock, AR. He holds a Bachelor's of Science in Biology and Biochemistry from University of Arkansas Fayetteville. Dr. Klucher then went on to earn his medical degree from University of Arkansas for Medical Sciences before completing his residency at the University of Maryland Medical Center in Baltimore in 2025.

Dr. Klucher joined WashU Medicine in 2025 for a combined Adult/Pediatric Infectious Diseases Fellowship, and after his first year with Pediatrics, he started with Adult ID in 2026. His clinical interests include antimicrobial stewardship; longitudinal pediatric into adulthood HIV, and sexual healthcare.

Why did you choose WashU Medicine for your ID fellowship?
"I appreciated the large volume of providers between adult and pediatric infectious diseases. The Program Director, Dr. Wooten, also referred me to the Program Director for Pediatric Infectious Diseases, Dr. Rosen, after reading my personal statement. She encouraged me to consider a dual fellowship, something I had previously given up on due to concerns for it being logistically too complicated. They were welcoming and encouraging which promoted my desire to come here. Ultimately, I had a gut feeling that this was the right place for me, and I'm super happy to be here now having completed my first year of Pediatric Infectious Disease fellowship."

Dr. Kotov's research expands on the theme of innate immune exacerbation of tuberculosis disease by continuing to study the role of plasmacytoid dendritic cells during infection and identifying additional mechanisms by which neutrophils and macrophages inhibit product responses against Mtb.

Dr. Kung is the Director of Infection Prevention for Washington University in St Louis.

Dr. Kyei specializes in HIV basic and translational research, with a special focus on viral latency and reactivation specifically:  (i) characterization of factors that control HIV replication in macrophages, dendritic and resting T cells and (ii) identification of cellular factors and small molecules required for HIV reactivation in latently infected cell and (iii) perspectives of HIV patients on HIV cure.

Dr. Lawrence’s research interests focus on the human immune response to viral infections and vaccines, the epidemiology of infections in solid organ and stem cell transplant recipients, and public health preparedness for pandemic COVID-19, Delta and other variants, pandemic influenza and bioterrorism events.

The Leung Lab is focused on developing a mechanistic understanding of host-pathogen interactions that contribute to viral pathogenesis through immune evasion.
