Find this physician on UBMDProfessional Summary:
I am an infectious diseases physician and clinical researcher, currently serving as Professor of Medicine and Chief of the Infectious Diseases Division at the University at Buffalo Jacobs School of Medicine and Biomedical Sciences. I lead a division of 14 physician scientists who provide clinical care across four medical centers; perform innovative research; and teach medical students, residence and fellows. Guided by service to community, I envision and work to create a world where our discoveries and staff are at the forefront of a global movement toward health equity and improved outcomes in infectious diseases.
Prior to joining UB, I served 23 years in the United States Navy as a Flight Surgeon, Internal Medicine, and Infectious Diseases physician. While living in Italy, Japan, Ghana, and Singapore on active duty, I developed a research interest in global health and biopreparedness. My research sought to improve the healthcare outcomes of our services members as well as the local public health. In my last position as Science Director at the Naval Medical Research Unit INDOPACIFIC, I oversaw a staff of 10 researchers conducting $9M in annual research in 11 different countries.
My current research interests include antimicrobial resistance; emerging infectious diseases; and biosecurity, specifically the intersection of AI, gene editing, and synthetic biology to understand and prepare for both natural and contrived pathogens. Collaborating with partners from around the world, I enjoy characterizing contemporary and novel disease threats and developing better ways to diagnose, treat, and prevent these pathogens from causing illness.
I believe, that everyone should always have a mentor and coach. Subsequently, I enjoy supporting the careers of undergraduate, graduate, and medical students, as well as residents, fellows, and junior faculty. I look to cultivate the next generation of infectious disease experts and public health leaders and involve them in my research.
