Professional Summary:

I care for patients who are hospitalized at Erie County Medical Center where I also serve as the hospital epidemiologist addressing infection control.

I teach medical students, residents, and fellows in both hospital and classroom settings. In UB’s schools of medicine and dentistry, I teach a variety of topics including microbiology, pharmacology and toxicology, oral biology, and gastrointestinal systems, host defenses, and global health.

I also conduct laboratory research on diarrhea-producing strains of E. coli bacteria. My lab focuses on enteropathogenic Escherichia coli (EPEC), Shiga-toxigenic E. coli (STEC, aka EHEC) and enterotoxigenic E. coli (ETEC). We are working on the role of intestinal host defenses such as nitric oxide and on the immune modulatory effects of adenosine. We have discovered that zinc can directly inhibit the virulence of pathogenic bacteria, and we are working on turning these laboratory findings into treatments. In our work on zinc we collaborate with Michael Duffey, PhD, in the Department of Physiology and Biophysics.

Recently we have discovered that zinc can inhibit the development of resistance to antibiotics in Escherichia coli and other bacteria. Zinc does this by its ability to inhibit the SOS response, a bacterial stress response triggered by damage to the bacterial DNA. We are collaborating with Dr. Mark Sutton of Biochemistry to better determine the mechanism of zinc in this regard.

I am interested in international medicine and global health and participate in an annual medical mission trip to Honduras, a trip in which student volunteers are encouraged to participate. Closer to home, I am a volunteer physician at Good Neighbors Health Center, a free clinic for the underserved on Jefferson Avenue in Buffalo. Resident physicians are encouraged to volunteer, and students may also be able to arrange clinical experiences.

I am Co-Medical Director, with Dr. Ryosuke Osawa, of the Erie County TB Clinic.

Learning experiences in my laboratory, in infection prevention and hospital epidemiology, or in international health, may be available for motivated students, residents, and fellows.
