My research interests lie in computer graphics and animation, particularly focusing on efficient numerical techniques for simulation of cloth, elastic solids, and fluids in physics-based animation.
Previously, I spent three years as an assistant professor at the University of Minnesota. Before that, I was a postdoc at the University of California, Berkeley under Prof. James O’Brien, and earned a Ph.D. from the University of North Carolina at Chapel Hill advised by Prof. Ming Lin.
Note: I am actively looking for PhD and MS(R) students to work with me. Applicants should have experience with either computer graphics or numerical methods, and should have strong mathematical and programming skills. If you are interested, you should apply through the IIT Delhi graduate admissions process, specifying computer graphics among your research interests and listing me as a potential supervisor.

Argus
An adaptive cloth simulator with implicit frictional contact, combining So-bogus and a modified version of ArcSim (see below).
admm-elastic
Source code for our SCA 2016 and TVCG 2017 papers on fast optimization-based simulation of hyperelastic materials.
ArcSim
A cloth simulator with adaptive anisotropic remeshing, robust optimization-based strain limiting, and data-driven elastic models for cloth.
Note: Consider using our more recent simulator Argus (see above), which features an accurate frictional contact solver and improvements to the remeshing scheme.
Berkeley Garment Library
A collection of geometric models of garments intended for use in cloth simulation.
Sand Simulator 2010
Source code for our SIGGRAPH Asia 2010 paper, “Free-Flowing Granular Materials with Two-Way Solid Coupling”.
ML-Dev
An Eclipse plug-in for programming in Standard ML. Now maintained by Andrius Velykis.
