I am currently doing technical work related to computational geometry, computer science, discrete math, and information theory. My recently concluded projects include desiging a MANET protocol, researching validation process guidelines of computer models of how humans think, low-bandwidth authentication, and a military logistics siumlator called CoreSim; also computational topology, "forecasting" (uncertainty, statistics, and graph algorithms) over large-scale informatics graphs; and statistical techniques for finding the root-cause of faults in networked computer systems. Current projects include data-streaming algorithms, e.g. approximate counting; the geometry of distance functions for comparing probability distributions in information theory; and mesh generation, e.g. uniform-random meshes.

My department had a few job openings for informatics and statistics; the application deadline was 3 April 2010 but I'm leaving the postings up for now because we will likely have similar openings in the future. See also the department's careers page.
These positions may involve working on the same types of problems as the Network Grand Challenge LDRD project; I led the "Forecasting" piece of this project.

I taught the course "ALGORITHMIC GEOMETRY AND MESH GENERATION" at UNM in Fall 2010.

I organized a workshop on combinatorial algebraic topology in late August 2009; we wrote a summary report.

Here is a 2002 paper [bibtex] by Batagelj and Zaversnik about core decompositions of networks that lists me as a "liason" author linking two cores of Computational Geometry, which I recognize as Cubit mesh generation and theoretical mesh generation; see pages 7-8.

Biography:

I received a B.S in Applied Math, Engineering & Physics from the University of Wisconsin-Madison in 1988. I received an M.S. (1991) and Ph.D. (1993) in Applied Math from Cornell University. I worked the summer of 1991 at Xerox PARC with Marshall Bern and John Gilbert. Since Oct 1992 I've been at Sandia National Laboratories. I researched triangular and tetrahedral meshing algorithms via a computational geometry approach from 1992-1993. I was part of the Cubit project, doing mesh generation R&D from 1993-2000, and project leadership from 2000-2002. I did things like researching algorithms and existence proofs for hexahedral meshes and optimization for assigning the right number of edges locally so the model can be meshed globally. I managed the Optimization and Uncertainty Estimation department from 2002-2007. I served in various capacities on various programs, including LDRD (internal research program) and NNSA's ASC program. I decided I missed building things and figuring things out for myself and moved on to technical work in 2007. Time will tell what I do now.
