Oleg Sofrygin, PhD, is a Postdoctoral Fellow at the Kaiser Permanente Northern California Division of Research. He holds a concurrent appointment as a Postdoctoral Scholar in Biostatistics at the University of California, Berkeley. His work at U.C. Berkeley is supported by the Bill and Melinda Gates Foundation, Healthy Birth, Growth, and Development Knowledge Initiative (HBGDki). Dr. Sofrygin's research focuses on the development of statistical methods for data-adaptive estimation of causal treatment effects in observational studies. He is interested in developing and disseminating open-source, machine-learning-based statistical software for analyzing longitudinal data. He is currently applying his software skills in the evaluation of the comparative effectiveness of diabetes treatments from large-scale, longitudinal electronic health record data. Dr. Sofrygin's other research interests include high-performance statistical computing, the estimation of causal effects of interventions in network-connected communities, and the design of simulation studies for causal inference. Dr. Sofrygin received his PhD in Biostatistics from the University of California, Berkeley. His dissertation work focused on semi-parametric estimation of causal effects in network-dependent data.
