Patient Care
This faculty member is affiliated with UBMD, practicing physicians who are also professors in the Jacobs School.
View this physician on UBMDProfessional Summary:
I have an outpatient clinic at UB’s Student Health Services 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 Kaleida Health where I serve as Hospital Epidemiologist. My work includes pandemic and bioterrorism planning activities for the hospital system 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.
