Dynamics Engineer @ U.S. Army TARDEC

from May 2011 to present day

U.S. Army Tank Automotive Research, Development and Engineering Center

I work on the Dynamics Team with Dr. Jayakumar to quantify the uncertainty in traditional terramechanics approaches and validate these approaches against experimental data. I am also assisting in the development of a state-of-the-art terramechanics testing suite for light-weight ground vehicles.

2010

Mobility & Robotics Engineer @ NASA JPL

from May 2010 to September 2010

NASA Jet Propulsion Laboratory

I worked on the Mobility & Robotics Team with Dr. Jain to model various dynamics systems in an effort to validate research-grade simulation tools. I simulated a hopper robot interacting with the granular material of an asteroid and optimized the landing approach in a non-uniform gravity field. I also worked on simulation visualization for presentation and debugging purposes.
