2025

It has been another busy year for our undergraduate mathematics programs, with many exciting changes on the horizon. This year, our Undergraduate Program Committee is leading teams of faculty members in a review of all four of our majors – Mathematics, Applied Mathematics, Analytics and Operations Research, and Scientific Computation – with a view towards modernizing and improving what our current programs offer. The intent is to both add breadth to our current course offering, and to add support to mathematics students in the form of discussions across all of our classes.

We mourn the passing of our colleague Craig Tracy. 

Craig Tracy was an American mathematician known for his contributions to mathematical physics and probability theory. Born in 1945 in England to a British mother and an American father, Craig was raised on a farm in Missouri. After obtaining a B.Sc. in Physics from University of Missouri (1967), he studied at Stony Brook University, where he obtained a Ph.D. in Physics with the thesis Spin-Spin Scale-Functions in the Ising and XY-Models (1973), advised by Barry M. McCoy. 

A recurring task in the physical and data sciences is the rapid evaluation of sums of the form (1)

$$u_i = \sum_{j=1}^N G(x_i - y_j) q_j, \quad i=1,2,\ldots,N,$$

I got my Bachelors of Science in Mathematics at UC Davis in 1987. I worked as an actuary on defined benefit pension plans for about 5 years, then I worked at a management consulting firm in Menlo Park called Applied Decision Analysis (ADA) for about 5 years. At ADA we did market research, market modeling, market analysis, decision analysis, and risk analysis. I started doing pricing strategy for tech companies in Silicon Valley in 1997 and I'm still at it.

Roger J-B Wets was a Distinguished Research Professor of Mathematics at UC Davis, who passed away in April 2025. He was well regarded as an inspiring mathematician and described by his students as an amazing mentor. He guided nineteen students to their Ph.D. and developed a Mathematical Finance course for our Department. Collaborators talk of both his brilliance at research, but also his kindness, good humor, and thoughtful personality.  

I recently completed my Ph.D. in Mathematics at Georgia Tech, where I was advised by Jen Hom. My research focuses on problems in low-dimensional topology, primarily from the perspective of knot Floer homology and bordered Heegaard Floer homology. At UC Davis, I look forward to working with Melissa Zhang and broadening my approach by exploring new tools for studying knots and links in 3- and 4-manifolds.
