Personal Statement

I am currently an Associate Professor in the Department Epidemiology and Associate Dean for Diversity, Equity, and Inclusion at the University of Pittsburgh, Graduate School of Public Health. I’ve held faculty positions at several other top-tiered Schools of Public Health including the Columbia University Mailman School of Public Health and the Johns Hopkins Bloomberg School of Public Health. I am an accomplished researcher having authored or co-authored over 120 scientific publications including journal articles, book chapters, and editorials. My current research agenda is the culmination of my 20+ years of experience working to understand the social/environmental determinants of chronic disease and implementing interventions to improve prevention and control. My research program is divided into three defined areas: 1) the social determinants of diabetes and obesity, 2) interventions to improve diabetes outcomes for Minority populations, and 3) translation of research findings to practice and real-world evaluation. I’ve held leadership positions in several national organizations including the American Diabetes Association (ADA), the American Public Health Association (APHA) and the Council on Black Health (CBH). I am now expanding my national and international reach to work on larger structural issues that will affect the nation’s progress toward understanding and eliminating health disparities.
