New Faculty - 2018

Sandra AlbrechT – Department of Epidemiology

Dr. Sandra Albrecht is formally trained as a social epidemiologist, with additional training in the social sciences, nutrition, and population health. Her research focuses on the socio-cultural and environmental factors that contribute to the progression of obesity and type 2 diabetes (T2D) in US immigrants, and among Latinos in the US and in Latin America using a variety of quantitative data sources. Examples of past research projects include investigating the social and environmental determinants of diet and weight gain in Latino and Chinese immigrants and exploring the role of ethnic enclaves in shaping nutrition-related outcomes in Latinos. With funding from an NIH/NIDDK Career Development Award (K01), Sandra’s emerging line of research seeks to understand the social and behavioral mechanisms underlying the high burden of T2D and associated complications in Mexican-Americans and other Latino subgroups. Previously, she was an Assistant Professor in the Department of Nutrition at the University of North Carolina (UNC) at Chapel Hill, and a Faculty Fellow at the Carolina Population Center at UNC.
