In just a few days I will hand the reins of the Department of Mathematics to the experienced hands of my colleague Joel Hass. Joel has served as department chair for 4 years (2010-2014). Through a number of leadership functions on campus he also acquired deep knowledge of all aspects of the university organization. I am very grateful he agreed to step back into the department chair role for 2026-27.
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.
