It's 2021. The start of a new decade is a good time to update one's website. I'll do it slowly. Apologies to the few kind folks who visit.

I grew up in public health and community development, and have had a chance to do different things in this space. I am fortunate that everywhere (in time and space) I have had inspiring colleagues and wonderful learning experiences. On a less self-centered note, I hope I have done some good -- more so than harm -- and apologize for any harm I have caused.

I am now an Assistant Scientist in the Department of Mental Health at Johns Hopkins, and a member of the Stuart lab. My work focuses on causal inference, specifically the reasoning and techniques that allow learning causal effects from observational data. I am interested in the handling of data limitations that complicate otherwise standard analyses, and the learning of effects that are themselves complicated. I aim for both rigor and user-friendliness. Topics I am actively pursuing include propensity score methods, mediation analysis, missing data and measurement error, generalizability/transportability, and treatment effect heterogeneity. To expand my tool kit for this work, I am doing PhD training at Hopkins Biostatistics part-time. 

It takes a village to raise a child, say some wise people in Africa. As a somewhat mature and stubborn child, I owe my recent and current raising to my advisors -- Amy Knowlton, Karen Bandeen-Roche, Renee Johnson, Elizabeth Stuart, Constantine Frangakis and Elizabeth Ogburn -- as well as my many formal and informal teachers, mentors and colleagues. All the flaws, however, are mine.

Here's me on ResearchGate, Google Scholar and arXiv. If you have trouble accessing any of my papers, let me know and I'll send you a copy.
