Short bio: I am a Stefan E. Warschawski Visiting Assistant Professor in the Department of Mathematics at the University of California, San Diego, mentored by Ioana Dumitriu. My primary research is in random matrix theory and numerical linear algebra, with an emphasis on applications to problems in numerical analysis, integrable systems, and statistical modeling, as well as relationships to random discrete structures, such as permutations, graphs and algebraic objects from number theory. I also am involved in educational research and outreach relating to equal access issues in STEM. I completed my Ph.D. in mathematics from the University of California, Irvine in 2021, under the advisement of Mike Cranston and Tom Trogdon (University of Washington). My dissertation, entitled "Numerical, spectral, and group properties of random butterfly matrices", can be found here. From 2021-2024, I was the Richard Pierce Postdoctoral Fellow in the Department of Mathematics at the University of Arizona, mentored by Nick Ercolani.
I completed my AB in mathematics from the University of Chicago in 2006. I then worked for 9 years in the "real world", first as a research analyst with the Social and Economic Sciences Research Center with Washington State University and then as a data analyst/BI engineer with the Office of Research Information Services at the University of Washington. I started my Ph.D. program one month after the birth of my first son (not pictured).
Outside of math, I enjoy running, watching movies, doing trivia, and spending as much time as possible with my family (me+wife+two sons+dog). Relocating back to California from Arizona, I no longer dabble in the hobby of relocating scorpions found in my backyard using a blacklight, which I am perfectly fine not doing anymore.
I am organizing the UCSD Probability Seminar this year.
