About me

I am an associate professor of epidemiology at Drexel University in Philadelphia, PA. My etiological research focuses on environmental influences shaping neurologic development, especially with regard to autism spectrum disorders, using population-based registers and databases and historical biobanks. A separate theme of my research focuses on the methodological toolbox necessary for causal inference in epidemiology.  Specific interests include biomarker characterization in epidemiologic studies, machine learning and data mining, and optimization of propensity score techniques.


2009 PhD Epidemiology, Johns Hopkins University
