Bio
Prof. Brisa N. Sánchez serves as Associate Dean for Research at Drexel University's Dornsife School of Public Health and as Dornsife Endowed Professor of Biostatistics. She earned a bachelor’s degree in Mathematics and a master’s degree in Statistics from the University of Texas at El Paso, and a PhD in Biostatistics from Harvard University. In 2006 she joined the Biostatistics Department of the University of Michigan, where she was later named John G. Searle Assistant Professor and was promoted to Full Professor with tenure in 2018. She joined Drexel in 2019. Prof. Sánchez is an active proponent of and participant in team science approaches to address public health challenges, to which she contributes not only her statistical knowledge and expertise but also her knowledge of a variety of research areas and enthusiasm for scientific discovery. Through immersion science content, she marries statistical rigor with practical considerations of the research questions at hand.
Prof. Sánchez develops and applies statistical methodology to study social and environmental determinants of health and health disparities. She leads methodological research to develop exposure assessment methods and to assess health impacts of neighborhood-level exposures (social and built environment) and their interactions with individual-level factors. These methods include enabling data-driven estimation of time and spatial scales at which environmental exposures shape health behaviors and downstream biological outcomes, and characterize the simultaneous impact of multiple, correlated environmental features on health, including social factors. This research has been funded through NIH grants, including "Characterizing health impacts of built environment features using complex data" (R01 HL131610, PI: Sanchez). Sánchez is internationally recognized for her work on latent variable models with environmental health applications.
She also has extensive expertise in research involving health disparities and cardiovascular disease, including stroke, as well as the effectiveness of nutrition policies geared toward improvement of children’s health and learning. She co-leads projects to evaluate how the food environment in schools, regulated through food nutrition policies for schools, impacts child health and learning, and how food environment near schools modifies the impact of school nutrition policies on student outcomes. These projects utilize longitudinal records on over 11 million children collected over more than 15 years (R01HL136718; R01HD111169; R01MD017687). In addition, she served co-Principal investigator of the NSF-funded, mixed-methods project, "Neighborhood Environments as Socio-Techno-bio Systems in Mexico City," which focused on how water infrastructure in neighborhoods shapes and is shaped by residents' trust in water and their health.
Her research has been published in leading statistical, epidemiology, and medical journals including JASA, Biometrics and the Journal of Applied Statistics, Statistics in Medicine, Epidemiology, American Journal of Epidemiology, Environmental Health Perspective, JAMA Pediatrics and Health Affairs. She has held multiple leadership roles in research collaborations, research administration, professional organizations, and has served on panels for the National Academies of Science. She served as Director or co-Director of several NIH-funded research centers, and currently also directs the Biostatistics for Social Impact Collaboratory. She previously served as Book Reviews Editor for Biometrics, a leading journal in biostatistics, as well as Associate Editor for Statistics in Medicine and the Journal of the Royal Statistical Society Series C. She has served in multiple elected positions for the Eastern North American Region of the International Biometrics Society and the Statistics Section of the American Public Health Association.
