Additional Information

I have over 27 years of industry experience in design, testing and structural analysis. Some of my projects in industry were:

  • Developing an automated Bearing Dynamometer at GE; tested sleeve bearings for Heat Transfer and torque and modeled with 1-D code.
  • Developing work flow and test reporting system at Navistar using Microsoft Access; later migrated to SQL server. Implementing an SGI Super Computer Cluster at Navistar Truck Development & Technology Center (TDTC) starting in 1999; initial Godzilla supercomputer was supplemented by Rodan, Mothra and Ghidra. Supercomputers used to develop Crash analysis capability using LS/Dyna.
  • Replacing the SGI Supercomputer with commodity off the shelf workstations running Linux operating system in 2002, 8X increase in power while elimination $250k/year hardware maintenance cost for older SGI hardware.
  • Developing in-house code to optimize vehicle scheduling using genetic algorithms; initially applied to ProStar development efforts in 2005.
  • Developing class leading Interior Noise and Vibration characteristics for the launch of ProStar and LoneStar class 8 Heavy Trucks; made significant improvements in door closing sound quality and wind noise.
  • Enhancing the TDTC compute cluster in 2009 with 56 Nehalem class cpu’s; allowed Fluent to be brought in-house with high cpu count license; reduced job time to 1/8th while saving $30k/month.
  • Although I have spent many years in industry, I have also had a long term interest in Engineering Education. I started teaching as an adjunct at Indiana Tech in 1988 and I am currently on a Ph.D. in Engineering Education from Purdue.
