He served on the committee of the Meshing Roundtable and International Symposium on Computational Geometry SoCG conferences.

As an adjunct professor, he taught a small graduate course on computational geometry at the University of New Mexico.

His main contributions have been geometric algorithms with provable correctness and output quality guarantees.

His PhD thesis was the first tetrahedral meshing algorithm with guarantees on both the number of elements and their shape.

He is also well known for a series of papers on whisker weaving and other algorithms for hexahedral mesh generation using the dual spatial twist continuum.
