I’m a Hedrick Assistant Adjunct Professor at the Department of Mathematics, UCLA. My research interests are varied but all relate to better understanding multiphase flows and fluid dynamics more broadly. I’ve done experimental investigations of iceberg melting rates, computational investigations on the extraordinary drag of the dead-water effect, and mathematical analysis on improving the volume-penalty method and phase-field models of melting and dissolution. A big reason I’ve been able to work on so many projects is because of the incredibly flexible and efficient Dedalus computational framework developed by my thesis adviser Geoff Vasil and his collaborators Keaton Burns, Daniel Lecoanet, Jeff Oishi, and Ben Brown.
