Kolczak Award for her contribution in methods for maternal vaccine research. Her focus areas include cardiovascular epidemiology, vaccine safety and effectiveness during pregnancy, and comparative analysis using observational data. She is an investigator for the Vaccine Safety DataLink and the Virtual Network for Effectiveness of Influenza and COVID-19 vaccines (VISION), and Sentinel networks to study medication safety.

Joined the Institute: 2010

Education and training: PhD, epidemiology and MSc, biostatistics, University of Minnesota, Minneapolis; MSc, demography, El Colegio de Mexico.

Overview/research interests: Multilevel data analysis, meta-analysis, generalized linear models, epidemiologic study designs, chronic disease epidemiology, pregnancy vaccine safety.
