Short Course Instructor Biographies 

Steve Owen, Sandia National Laboratories

Steve Owen is a senior member of the technical staff at Sandia National Laboratories in the Parallel Computing Sciences Department. He curently works on geometry related issues and unstructured meshing algorithms within the CUBIT software at Sandia. Steve received his Ph.D. from Carnegie Mellon University in Pittsburgh, Pensylvannia and B.S. and M.S. degrees from Brigham Young University in Provo, Utah. Prior to Sandia, Steve worked at Ansys Inc, a commerial FEA company, developing unstructured mesh generation codes. Much of the work he completed for his Ph.D. has also been incorporated into the Ansys software. Recent work involved development of a new hexahedral-dominant mesh generation algorithm known as Hex-Morphing and an all-quad meshing algorithm known as Quad-Morphing. Steve also maintains the "Meshing Research Corner" website, a comprehensive site dedicated to current literature and software related to unstructured mesh generation

Peter Schreuder, California Institute of Technology

Peter Schreuder is an Associate Professor of computer science at the California Institute of Technology where he began his academic career in 1995. Prior to Caltech and a short stint as postdoctoral research fellow at Interval Corporation (summer 1995) he was a postdoctoral research fellow at the University of South Carolina department of mathematics and a lecturer in the computer science department, where he worked with Prof. Bjrn Jawerth and Dr. Wim Sweldens. He received his PhD in computer science from Princeton University in 1994 for work on "Wavelet Methods for Illumination Computations." Prior to Princeton he was a member of the technical staff at Thinking Machines, where he worked on graphics algorithms for massively parallel computers. In 1990 he received an MS degree from MIT's Media Lab. He did his undergraduate work at the Technical University of Berlin in computer science and pure mathematics. He has also held an appointment as a visiting researcher with the German national computer science research lab (GMD) and its visualization group.

Prof. Schreuder is a world expert in the area of wavelet based methods for computer graphics. He helped pioneer the use of fast wavelet solvers for illumination computations and developed (with Dr. Sweldens) the first practical spherical wavelet transform. Multiresolution techniques have been the subject of many invited lectures and courses he has given in Europe and North America for academic and industrial audiences. His publications record ranges from WIRED magazine to Siggraph conferences and special scientific journal issues on wavelets. In 1995 he was awarded a NSF CAREER award and named a Sloan Fellow. More recently he was named a Packard Fellow.

TOPIC: Global optimization of mesh quality
David Eppstein, University of California, Irvine

David Eppstein received a B.S. with distinction in Mathematics from Stanford University in 1984, and M.S. and Ph.D. degrees in Computer Science from Columbia University in 1985 and 1989. After a one-year postdoctorate at the Xerox Palo Alto Research Ctr., he joined the faculty of the University of California, Irvine, Dept. of Information and Computer Science, where he is now a full professor.

Prof. Eppstein's research interests are primarily in the areas of graph algorithms and computational geometry. He received an NSF National Young Investigator award in 1992. He currently serves on the editorial boards of the Journal of Algorithms, SIAM Journal on Computing, Journal of Graph Algorithms and Applications, and Chicago Journal of Theoretical Computer Science. Prof. Eppstein is program co-chair for the 2001 ACM Symposium on Computational Geometry and program chair for the 2002 ACM/SIAM Symposium on Discrete Algorithms.

TOPIC: Optimality and Guaranteed Quality in Isoparametric Mesh Generation
Stephen Vavasis, Cornell University

Stephen Vavasis is an Associate Professor of Computer Science at Cornell University. He received his PhD from Stanford in 1989. In the past 10 years, he has held summer or sabbatical research positions at Sandia National Laboratories, Argonne National Laboratories, Bell Labs, Xerox Palo Alto Research Center and RIACS (NASA-Ames). His research areas are numerical analysis, optimization and computational geometry. He is the author of the QMG mesh generation software package, which is based on an algorithm developed jointly with S. Mitchell. He is a previous winner of an NSF Presidential Young Investigator award and a Guggenheim Fellowship.
