Head of the Applied Geometry lab Our lab focuses on applying discrete differential geometry to a wide range of fields and applications. In particular, we approach computations from a geometric standpoint in order to provide differential, yet readily-discretizable computational foundations. Our efforts include: · Discrete Exterior Calculus: providing the means to handle basic computations without violating the symmetries and invariants that differential modeling defines for predictive purposes. · Simulation techniques: from Computational Fluid Dynamics (circulation-preserving discrete fluids and discrete variational fluids) to Discrete Elasticity (thin shells and deformable objects).. · Meshing: 2D and 3D sampling, meshing, and remeshing for accurate simulations. · Graphics: surface modeling via mesh processing, compression, animation, etc… Current members: Patrick Mullen, Alex McKenzie, Roger Donaldson, Ari Stern, and Lily Kharevych.

Research Community Involvement, Past and Present Associate Editor of the ACM Transaction on Graphics journal; program committee member for the ACM SIGGRAPH conference and other international symposia; chair of the Symposium of Computer Animation and the Symposium on Geometry Processing; review panelist for NSF and DOE programs; reviewers in various computational science and computer science journals.
