My research covers a variety of topics in statistics and data science, typically motivated by scientific questions in global health, economics, demography, and sociology. Recent projects include estimating features of social networks (e.g. the degree of clustering or how central an individual is) using data from standard surveys, inferring a likely cause of death (when deaths happen outside of hospitals) using reports from surviving caretakers, and quantifying & communicating uncertainty in predictive models for global health policymakers. More information about OpenVA, our suite of open tools to manage and analyze verbal autopsy surveys, is available here.

I’m the former Editor of the Journal of Computational and Graphical Statistics and a 2019 recipient of the NIH Director’s New Innovator Award. I was elected as a Fellow of the American Statistical Association in 2023.

An description of some of our work recently appeared in the Wall Street Journal and it was used for a visual story in the Washington Post.
