Dr. Daniela Sotres-Alvarez is a research assistant professor in the Department of Biostatistics.

She is interested in collaborative research in obesity and nutritional epidemiology, and particularly in research that applies statistical methods to assess and correct measurement error in dietary intake and physical activity. Dr. Sotres-Alvarez's primary research experience and interests include measuring dietary intake, physical activity and their association with health.

She has been a biostatistician and co-investigator at the Coordinating Center of the Hispanic Community Health Study/Study of Latinos (HCHS/SOL), since August 2010. She also is the Primary Investigator of the Coordinating Center subcontract for HCHS/SOL Ancillary Study SOLNAS. Her areas of statistical expertise include categorical data analysis, linear mixed models, latent variable models and complex survey analysis.
