I’m a 2nd-year computer science PhD student at the University of Toronto. I work with Prof. Eitan Grinspun on geometry processing and numerical simulation. I study differentiable methods for solving partial differential equations for visual computing and computational design.

Before my PhD, I was a Software Engineer at Microsoft. I worked on the Azure Kubernetes Service (AKS) infrastructure team. During my undergraduate studies, I researched medical imaging with the University of Pennsylvania University of Pennsylvania X-ray Physics Lab, under the supervision of Prof. Bruno Barufaldi.
