James Uanhoro

Bio

I am a fourth-year doctoral candidate within the Quantitative Research, Evaluation and Measurement program in the Educational Studies department at Ohio State University. My advisor is Professor Ann O’Connell. I have a background in Information Systems, and in my downtime, I enjoy using my computing skills to develop statistical tools for applied researchers. For my dissertation, I am using the connection between SEM and regression to develop complicated SEM models for non-Gaussian data; the estimation method is Bayesian. My interests are causal inference, applied Bayesian modeling, communicating statistical findings, statistics education, API development.
