Katherine (Kat) Hoffman
I am an MS-level biostatistician and fourth-year Biostatistics PhD student at the University of Washington. I am advised by Dr. Marco Carone and develop statistical methodology motivated by challenges that arise in infectious disease and vaccine research. My work is supported by Dr. Helen Chu in the Department of Medicine.
I am driven by the goal of advancing rigorous, reproducible biomedical research. My primary interests lie in causal inference, particularly for settings involving time-varying or continuous exposures and time-to-event outcomes.
Outside of my research collaborations, I enjoy writing blog posts about statistics, programming, and career-related topics. For many of my posts I create illustrations and infographics, such as my Visual Guides for Causal Inference series.
