Bachelor Degree in Physics, California Institute of Technology 1994
System Programming: Working knowledge of C++/Unix (on HPUX Linux) and Perl, also to Lisp, Java. Image conversion/manipulation tools.
Mathematic/Scientific programming: Module Programming in AVS (Advanced Visual Systems) Volume Data Analyser for MRI acquisition parameter optimization. Multi-res, multi-processor rendering. Volume Ray Tracing.
Web Programming ArsDigita Community System's 3 week Bootcamp: Programming the AolServer with Tcl and Pl/SqlPlus to do remote-site quering, xml data sharing, infrastructure building for collaberative sites.
Caltech Computer Graphics Lab [April 1991 to Mar 2000]
[91 to 94] Extended MRI-data C++ library to read/write Huntington MRI format. Extended in-house polygon ray tracer to include spheres cylinders and b-spline deformed volume data and allow arbitrary interpenetration. Generated/edited the lobster sequence in the 1993(?) SIGGRAPH movie "Fruit Tracing"
[94 to 96] Designed developed user interface, statistics and solver package for MRI Parameter Optimization System on HPUX written in Perl/C++.
[96 to 98] Helped design volume visualization system in AVS and wrote several of its AVS modules.
[98 to 00] Ported graphics group system software to SGI architecture. Worked on mesh generation from inclusion function data code. Worked on interfacing ray tracer with implicit function solver to implement implicit object tracing. Worked on porting ray tracing system to linux.
Caltech Computation and Neuro-Systems Lab [July '87 to April '89]:
Implemented a real time edge detection system on an Intel pc.
Designed and wrote module simulating the spacial aspect of retina image processing for a of a cat visual system simulation.
Wrote Macintosh program for a psycho-physical experiment on Second Attention.
