This is my first year as GGAM Chair and the first time I have the honor of writing this column. I took over from Javier Arsuaga last summer. Javier did an incredible job moving GGAM forward—many thanks to him—and I am grateful to be able to build on and continue that work.
Gentle reader, you are reading the second issue of our new quarterly newsletter! As you may have noticed, the format of our newsletter has changed. We have retired our annual printed newsletter and hope you are enjoying our new digital quarterly newsletter. We encourage you to comment and make suggestions, especially since we are still working on the format of the digital newsletter and eager to improve.

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.
Imagine a boulder in a stream. As the water hits the boulder, it splits around the object. Once it’s passed around, the two flowing streams crash together, creating turbulent conditions that, if visible, would manifest as chaotic whorls and vortexes. This isn’t just true of water. It’s true of all fluids, including air.
The mathematical equations underlying fluid motion — known as the Navier-Stokes equations — are among the most notoriously challenging partial differential equations because in principle they encode complex behaviors similar to the one you just imagined.
During the 2023-2024 academic year, my second year as chair, I focused on getting the new degree requirements approved and on adapting the Group to the new budgetary challenges that the University is facing.
