I am an assistant professor at Center of Visual Computing, Computer Science and Engineering, UC San Diego.

Prior to the current position I was a postdoctoral researcher in Mathematics at Technische Universität Berlin, the geometry research group (Discretization in Geometry and Dynamics). I received my PhD (2017) in Applied and Computational Mathematics at California Institute of Technology advised by Professor Peter Schröder. Prior to the PhD study, I received a master (2012) and bachelor (2011) degree in Mathematics at National Taiwan University.

I am interested in the mathematical problems emerging in computer graphics, in particular geometry processing and physics simulation. This is the area where we find exciting interplay among differential geometry, algebraic topology, differential equations, and computational mathematics. This includes physical modeling in geometric language that yields novel description to fluid dynamics, and discretization methods that preserves structures in their continuous analogs.

Besides academic interests, I am also an amateur Houdini programmer, drawing artist and classical pianist.
