IPC: Incremental Potential Contact (IPC) for implicit time stepping nonlinear elastodynamics with frictional contact. IPC guarantees intersection- and inversion-free trajectories across wide ranges of nonlinear material models, time-step sizes, velocities, and deformation severities.

NASOQ: Numerically Accurate Sparsity Oriented QP (NASOQ) solver for sparse quadratic program (QP) problems. NASOQ is a full-space QP algorithm that provides accurate, efficient and scalable solutions of QP problems.

TLC: Total Lifted Content (TLC) for computing injective mappings in 2D and 3D. TLC is an energy whose minimization is designed to map source meshes into target domains while preserving local injectivity. TLC does not require injective starting configurations which are often unavailable.

DOT: Decomposed Optimization Time integration (DOT) for implicit time stepping nonlinear elastodynamics. DOT is a domain-decomposed optimization method especially suitable for large time step simulations of deformable bodies with nonlinear materials and high-speed dynamics.

OptCuts: Joint optimization of surface cuts and parameterization. Simultaneous, automated optimization of distortion and seam cutting for 3D mesh parameterization problems.

BCQN: Blended Cured Quasi-Newton (BCQN) for distortion optimization. BCQN minimizes distortion energies (Neo-Hookean, Mooney-Rivlin, MIPS, Symmetric Dirichlet, Conformal Distortion and ARAP) for 3D and 2D deformation problems and for parameterization.

Staggered Projections and Generalized Reflections are available in SCISim, our framework for structure-preserving simulation of frictional contact and impact.

Simit, a programming language for physical simulation.

Codimensional-IPC and IPC were both featured in Kàroly's two-minute papers series.

Our Physics Whiz project was previewed as an Adobe MAX 2020 Sneak. This is joint work with Jui-Hsien Wang and Jérémie Dumas.

Adobe Character Animator won a 2020 Technology and Engineering Emmy Award for its pioneering contribution to live-performance animation. Glad to be a part of this great team.

We organized a BIRS workshop on Computational Contact Mechanics, Banff, February, 2014.
