In our lab, we are working on ways to understand how engineered systems can be controlled (spacecraft, robots, human-machine interfaces), and how natural systems control themselves. In addition, we explore how robotics and controls can be used as tools for basic neuroscience, biology, and animal behavior studies.
We have a variety of ongoing projects within the laboratory, and we are currently supported by:
National Science Foundation
NASA Ames Research Center
The Hartwell Foundation
Shriners Hospital for Children
I teach undergraduate courses in Dynamics (ENG102), Control Systems (EME172), and Space Mission Design (EAE141), and graduate courses in Control Systems (MAE272) & Autonomous Robotics (MAE252).
