Consulting Activities:

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.

Education:

Master of Science in Computer Science

Master's Program Advisor: Dr. Fikret Ercal

University of Missouri-Rolla

Bachelor of Science in Computer Science

University of Missouri-Rolla

Honors and Other Accomplishments:

NVIDIA CUDA Fellow: NVIDIA 2010 CUDA Fellows Announcement, UIUC Press Release

2010 HiPEAC Paper Award for the paper "An Asymmetric Distributed Shared Memory Model for Heterogeneous Parallel Systems" presented at ASPLOS 2010.

Tachyon, the ray tracing package I originally wrote for my Master's Thesis and continue to maintain today, was selected as a finalist for the SPEC MPI benchmark and is now part of the SPEC MPI2007 benchmark suite.

I'm a member of ACM and IEEE.

I hold an FCC Amateur Extra Class radio license and a GMRS radio license.

I have served the Champaign-Urbana Astronomical Society (CUAS) as Vice President (2008, 2009, 2010), and Fifth Director (2013).

17th Place in 21st Annual ACM International Collegiate Programming Contest,

1996 World Finals, Philadelphia PA

1st Place in 1996 ACM Mid-Central Regional Programming Contest

First Place Prize Winner: Intelligent Systems Center Graduate Research Paper Presentation Contest, University of Missouri-Rolla, April 20, 1996

Prize Winner: Intelligent Systems Center Graduate Research Paper Presentation Contest, University of Missouri-Rolla, March 30, 1995

I was a member of the Upsilon Pi Epsilon international computer science honorary society while a graduate student at University of Missouri-Rolla. I served as the treasurer for the local chapter in 1995.

I was a member of the Kappa Kappa Psi national honorary band fraternity while a graduate student at University of Missouri-Rolla.

I was one of the founding members of the University of Missouri-Rolla Solar Car Team while an undergraduate student.

I was a member of six man team (itself part of the ISRA junior team) that won the 1990 National Trophy Rifle Team match at the National Trophy Rifle Matches at Camp Perry, Ohio
