Dr. Koch's primary methodological research interests are in causal inference, machine learning, variable selection, and Bayesian modeling. He is particularly interested in causal inference with observational data in small samples, and heterogeneous treatment effect estimation in randomized studies. He collaborates with the Department of Otolaryngology in the College of Medicine.
