About
Hello! I'm Alvin, a Ph.D. student working at the Yale Computer Graphics group under Dr. Theodore Kim. My main research interests are in deformable simulation and geometry processing, specifically for hair.

We present geometric methods for generating shapes that are
characteristic of highly coiled hair. Different features become
visually relevant when hairs are well-approximated by high-frequency
helices instead of low-frequency curves, so we present algo... Show more
We present an isotropic, hyperelastic model specifically designed for the efficient
simulation of tightly coiled hairs whose curl radii approach 5 mm. Our model is
robust to large bends and torsions, even when they appear at the scale of the strand
dis... Show more
We analyze a wide class of penalty energies used for contact response through the lens of a
reduced frame. Applying our analysis to both spring-based and barrier-based energies, we show
that we can obtain closed-form, analytic eigensystems that can be used to guarantee positiv... Show more
