Consulting Activities:

I serve as a consultant to Delcross Technologies LLC for the GPU and MPI-based parallel computing aspects of the projects:
  • "Graphics Processing Unit (GPU) Acceleration for Cosite Interference Prediction Tools", SBIR N131-008, funded by NAVAIR, U.S. Navy, 2013-present.
  • "Antenna Placement Optimization on Large, Airborne, Naval Platforms", SBIR N101-022, funded by NAVAIR, U.S. Navy, 2010-2013.

I served as a consultant to Verachem LLC for the GPU parallel computing aspects of the project:
  • "Multilevel Parallelization of Software for Accurate Protein-Ligand Affinities", SBIR PAR-07-160, 1R44GM088867, funded by the National Institutes of Health, 2010-2014.

I served as a consultant to Production Data Services, developing tools for 3-D stereoscopic movie production. I developed and maintained a sophisticated software module for synchronized 3-D stereoscopic display of asynchronous, parallel-decoded video streams that formed the basis of the RushPlay 3D digital dailies system used in producing the Lionsgate 3-D movie My Bloody Valentine 3-D, released in January 2009.

Previous Employment:

I was previously a Senior Programmer/Analyst at Heuris/Pulitzer, and later Heuris Logic, developing commercial video encoding and transcoding software used in service bureaus, the standalone commercial MPEG Power Professional software, and plug-ins for the leading non-linear video editing systems. My work in this era was noteworthy mainly for my early use of parallel processing and SIMD instruction set extensions for acceleration of the routines for color space conversions, image filtering and de-noising, and motion estimation within the video encoder subsystem.
