Research

In my most recent research, I developed a machine learning method for causal inference on observational data, fused extended two-way fixed effects (FETWFE). Uses for FETWFE include estimating the causal effect of a law or policy that is implemented state-by-state. My paper with my advisor Jacob Bien on estimating probabilities of rare events, like purchasing an item from a display ad, was accepted to the Fortieth International Conference on Machine Learning (ICML 2023). Finally, I also developed a method for stable feature selection with Prof. Bien. One application for our method is improving identification of DNA nucleotides associated with phenotypes in genome-wide association studies. These sorts of studies have been effective in applications ranging from providing targeted treatment for Hepatitis C to improving grain yields.
