Biography

I have been developing and implementing computational methods for multibody systems for 18 years. Joined JPL at 1998 as a member of technical staff, Ive sucessfully developed rover models and simulation methods used for MER surface operation and Rover Analysis Modeling and Simulation (ROAMS) software.

Started at 1987, I developed a class of numerical integration algorithm for the real-time driving simulator in the University of Iowa, later implemnted the numerical integration to support the National Advanced Driving Simulator (NADS) at the universitys research park. After graduated from the Applied Math. program, I joined Comupter Adied Design Software Inc. (CADSI), where I implemented and developed new computational methods for the vehicle system design and simulation. At 1993, I joined Army High Performance Computing Reserach Center (AHPCRC) at the University of Minnesota at Twin City. My reserach is focused on the computational methods for highly oscillatory dynamic systems in the next four years at the center. In the meantime, I also served as a reserach faculty at the Automotive Research Center of University of Michigan. From 1996-98, I led the project to create a simulation of Ford automotive assembling line. This project was awarded by Engineering Animation Inc. (EAI) at Ames Iowa. At the same time, I also led another project for modeling and simulation of Armys track vehciles at United Defense, LP in Minneapolis, Minnesota.
