Areas of Expertise

Health education. As a course director, co-director of the ethics & humanities theme, head of the Geisel curriculum redesign 2011-2015, chair of the Geisel Academy of Master Educators 2016, and director of education at The Dartmouth Institute, my prime goal is to enhance health relevance and soul in medical and public health education.

HIV/Tuberculosis Immunology. Through the Dar Dar Trial, the largest trial of a new TB vaccine candidate in the world to date, we have analyzed how spontaneous and vaccine-mediated immune responses protect HIV-infected adults from TB. We are now moving a new candidate vaccine, DAR-901, through early phase clinical trials.

Clinical ethics. I chair the Clinical Ethics Committee at Dartmouth-Hitchcock Medical Center, which seeks to provide clinical consultation, education and policy support for clinicians, patients and families.
