Dr. Koyama's primary research interests revolve around flexible experimental designs for clinical trials and inference from the data that such flexible and adaptive designs produce, both in the Frequentist and Bayesian paradigms. He currently teaches the graduate-level course "Clinical trials and experimental design," and his collaborative research interests include comparative effectiveness research of treatments for localized prostate cancer and association between acute lung injury and air pollution, among others.
