About me

I am currently an associate professor in the Department of Epidemiology and Biostatistics at the Saint Louis University College for Public Health and Social Justice.

I have a special interest in statistics education and literacy, both for future statisticians and other data analysts as well as the general public. My research interests include causal inference and model-based adjustments for confounding, selection, and non-response biases, as well as estimating variation in treatment effects. I have published in fields such as statistical methodology, public health, health care, social work, criminal justice, and communication disorders.
