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.

- Foundations of Quantitative Analysis and People Analytics for the Harvard Business Analytics Program, Harvard Business School in Fall 2018
- Statistical Inference I - Statistics 211, Harvard University in Fall 2017 with Lucas Janson
- Data Science - Computer Science 109B, Harvard University in Spring 2017 with Mark Glickman and others
- Statistical Inference I - Statistics 211, Harvard University in Fall 2016 with Tirthankar Dasgupta
- Introduction to Data Science - Biostatistics 260, Harvard University in Spring 2016 with Rafael Irizarry and Stephanie Hicks
- Data Science - Computer Science 109, Harvard University in Fall 2015 with Joe Blitzstein and others
- Introductory Probability and Statistics for Business - Statistics 21, U.C. Berkeley in Spring 2012

I've also helped create material for these courses. Here are some examples

- Lesson on Cross-validation, Linear and Logistic Regression for Introductory Data Science in Fall 2015 with video lecture
- Lesson on Decision Trees and Random Forests for Introductory Data Science in Fall 2015 with video lecture
- Discussing Final Projects and discussing an example for Introductory Data Science in Fall 2015 with video lecture
