I am currently a Visitting Assistant Professor in the Department of Mathematics at the University of Rochester in Rochester, New York. I am currently researching topics related to random matrices and dynamical systems. My primary research interests are in Random Matrix Theory and Probability. I recently received my PhD in Mathematics from the University of California, Davis in June 2021.

- Pair dependent linear statistics for circular random matrix ensembles. 2021. My Dissertation. Available from ProQuest Dissertations & Theses Global.
- Pair Dependent Linear Statistics for CBE with Alexander Soshnikov and Ander Aguirre. 2019. Random Matrices: Theory and Applications.

Here is a list of some of the conferences and workshops that I have attended. Hopefully there will be many more to come in the near future!

- Finger Lakes Probability Conference (2023)
- XVI Brunel-Bielefeld Workshop on RMT and Applications (Poster Session Presenter, 2020) [Poster]
- 11th Cornell Probability Summer School (June 2019)
- CRM Workshop

Topic: Spectral Theory of Semi-Periodic and Random Operator (Nov. 2018) - International Congress for Mathematical Physics (ICMP) (Aug. 2018)

- qKZ is a SageMath package that I wrote in Spring 2017. This package generates and impliments operations on wheel polynomials, a family of polynomials studied by Dan Romik in his paper titled "Connectivity patterns in loop percolation I: the rationality phenomenon and constant term identities". This package has two variations: a 'non-threaded' version and a 'threaded' version which uses parallel computing to drastically improve computational performance. This project was inspired by a reading course supervised by Dan in Spring 2017.
