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, numerical simulations of phase separating polymer solutions and the extraordinary boat drag of the dead-water effect, and mathematical analysis of accretion disk shocks around black holes, as well as higher-order accurate volume penalty and phase-field models for melting and dissolving fluid-solid interactions using the elegant differential geometry of signed distance coordinates. I am especially motivated to implement my research by developing computational tools to simulate multiphase fluid dynamics and automatically derive boundary layer equations in arbitrary geometries. I also love visualising my research!
