Hospital-based provider only

Professional Summary:

My primary patient care activites involve hospitalized patients at the Department of Veterans Affairs Medical Center (VA) in Buffalo.

I also have an outpatient clinic at UB’s Student Health Center on the South Campus where I see students for general ambulatory infectious diseases such as skin infections, positive tuberculosis skin tests, etc. I also see students before they travel internationally for care such as immunizations and risk avoidance education and, if needed, for post-travel care and follow-up.

I teach first- and second-year medical students in lectures and small group sessions, primarily in the microbiology, respiration, musculoskeletal and reproductive modules. I also teach third- and fourth-year medical students, residents, and fellows on the infectious diseases and internal medicine services at the VA.

In addition to patient care and teaching, I have significant roles related to infection prevention and antimicrobial stewardship at two of Buffalo’s major health care systems, and I serve as Hospital Epidemiologist for both. My work includes pandemic and bioterrorism planning activities for these hospital systems as well as the University at Buffalo. These responsibilities require that I collaborate with hospital infection control teams, pharmacists, microbiologists and administrators (particularly the offices of quality management, risk management and patient safety) and with UB’s Student Affairs team. I also interact frequently with local health department staff.

Our infection control efforts have been based on the epidemiologic paradigm of hypothesis development, data collection and critical interpretation of the data followed by a rational and directed action plan. This is done for routine infection prevention, outbreak and cluster investigation, healthcare worker safety and antimicrobial stewardship.
