Research Themes
Curvature, boundaries, and flows.
The common thread is stability: of horizons, vacua, interfaces, hypersurfaces, and mathematical descriptions.
QFT in Curved Spacetime
Dynamic Casimir effects, sudden boundary changes, particle creation, and semiclassical backreaction.
Fluid Mechanics
Interfaces, drops, jets, and the correspondence between Rayleigh-Plateau and Gregory-Laflamme instabilities.
Geometry, Dimensional Analysis, and Finance
Constant-mean-curvature hypersurfaces, constrained dimensional analysis, and mathematical aspects of finance and economics.
