Teaching

In Fall 2023, I am on family leave from Grinnell College and will return in Spring 2024.

Previously, I have taught

Research

My research lies in the intersection of Probability, Statistics, and Mathematical Physics, in the field of Random Matrix Theory—a discipline that originally arose in multivariate statistics from an interest in estimating the covariance matrix of a random vector sampled from a large population. Currently, I study the solvability of $\beta$-ensembles of random matrices for integer values of $\beta$ beyond 1, 2 and 4.

A short description of my research interests can be found here (and here is a not-so-short description).

Projects

Past Undergraduate Projects

Grinnell Mentored Advanced Projects

  • In Summer 2023, I co-advised two Grinnell students, Max Worth and Mark Krysan, on a Mentored Advanced Project alongside Prof. Ryan Miller. This project aimed to improve the modeling and data handling methods used in previous statistical analysis of drivings simulator time series data, with the specific application to assess the influence of acute cannibis use on driving behavior.

Reed College Science Research Fellowship

  • In Summer 2023, I collaborated with two Reed students, He Bai and Asa Ferguson, as well as with Reed Professor Leonard Wainstein, on a project seeking to unify multilevel and fixed effects approaches to generalized linear models and penalized regression.

  • In Summer 2020, I advised a Reed Student, Jonathan Li, on a research project using statistical modeling and Monte Carlo methods to investigate the stochastic behavior of certain classes of random tensor objects.
