Brisa N. Sánchez is an Associate Professor of Biostatistics. She received her Ph.D. in Biostatistics in 2006 from Harvard University. She joined the University of Michigan in 2006 as an Assistant Research Professor, and became an Assistant Professor in 2008. Her research interests are in statistical methodology applicable to environmental epidemiology, and social epidemiology, and health disparities.
Her current methodological work involves developing robust fitting procedures and diagnostics for Structural Equation Models, and using these methods in applications to environmental health problems such as in-utero lead exposure and its effect on child development. She also conducts research on study design for longitudinal studies, in particular the design of studies involving salivary cortisol as a measure of stress in health disparities research. Sanchez also investigates the applicability of various functional data methods to studies of salivary cortisol.
Her collaborative research spans environmental epidemiology, social epidemiology, and health disparities in the areas of cardiovascular disease, stroke, and the distribution of body mass index. Within environmental epidemiology, her work focuses on the impact of lead and air pollution exposure on birth outcomes, and child development and behavior. Her work on health disparities and social epidemiology has included the analysis of the effectiveness of school level interventions to reduce child obesity, among others.
