Statistics Ph.D. Student

Harvard University

I'm a Graduate Student in Statistics at Harvard University.

In recent years I've become interested in understanding the principles that lead to successful model building and developing tools to guide practitioners to this end. One instance being tools for detecting practically unidentifiable parameters in Bayesian Models. These methodological developments have always been guided by collaborations with wonderful researchers in public health, political science and, recently, astrophysics. You can find a list of past and current projects below.

In my past I studied Mathematics and Statistics at the University of California, Davis, then more Statistics at University of California, Berkeley. After I had had enough of studying, I spent some time consulting in the San Francisco bay area before taking a position as a Statistician in the Biostatistics unit of the UC Irvine Institute for Clinical and Translational Sciences. I've always believed in developing statistical methodology using the bench-to-bedside approach and my time at UC Irvine helped me solidify this in practice.

I've had the pleasure of assisting in teaching several semester-long courses, here are some.
