Research/Areas of Interest:

I have focused my research efforts on infections in immunocompromised patients and on S. aureus, a dangerous bacterium that can evade some commonly used antibiotics. My leadership role in the Stuart B. Levy Center for Integrated Management of Antimicrobial Resistance, the Levy CIMAR, is an outgrowth of my long-standing commitment to research on bacterial pathogens that pose significant health risk.

I have been a member of the TUSM family since 2002 when I was recruited to the Division of Geographic Medicine and Infectious Diseases at Tufts Medical Center, and served as Director of the Infectious Diseases Fellowship for 14 years before being named Division Chief. Most recently, I've been engaged in the COVID-19 response across Tufts Medicine, our health system.
In my role as Dean, I will have a focus on helping TUSM become an anti-racist organization, and on continued integration with our affiliate partners to further advance our excellent teaching and research programs. My role also includes service as the Chief Academic Officer of Tufts Medicine which will provide a unique opportunity to contribute to the growth of our academic and research missions.
