My clinical interest work focuses on infectious diseases, particularly those caused by Staphylococcus aureus. I practice medicine and infectious diseases at the VA Western New York Healthcare System. The service here treats veterans with a wide variety of infectious diseases, including HIV and hepatitis C. I attend on the inpatient service. Medical students, residents, and fellows evaluate and follow infectious disease consultations with me on the inpatient service.
I am also an Associate Dean for Medical Curriculum at the Jacobs School and I teach extensively in the Medical School. I also serve as Vice Chair for Education in the Department of Medicine. I enjoy working with students throughout the full spectrum of medical education, from first-year medical students to senior fellows in Infectious Disease.
My research interests dovetail with my clinical work. I currently do mainly bioinformatics projects on the large VA database with an emphasis on the COVID-19 pandemic. I previously studied Staphylococcal infections, particularly complications related to S. aureus bloodstream infections. That work made use of bioinformatics and database design, techniques that support my ongoing collaborations with other investigators on bioinformatics problems, particularly with Moraxella catarrhalis and Haemophilus influenzae.
Prior to my studies in S. aureus, I conducted research on a fascinating pathogen, H. influenzae biogroup aegyptius and Brazilian Purpuric Fever. Over that 10-year period my laboratory identified a unique epitope on a surface proteins associated with the disease. We were able to create the only isogenic mutant so far described with this pathogen that is highly refractory to genetic manipulation.

Infections with Staphylococcus aureus: I have both a research and clinical interest in infections caused by Staphylococcus aureus. My clinical interest involves blood stream infections and community-associated MRSA infections. My research interests center on the clinical and molecular epidemiology of blood stream isolates, including whole genomic sequencing and the bioinformatic approach to analyzing virulence factors.
