Last seen: presque 3 ans il y a Actif depuis 2015

I recently completed a PhD from Cornell University in robotics and now work in industry doing high-level robotics control. I am interested in:
- non-linear dynamics and control
- robotics
- path planning
- legged locomotion
- bipedal walking
- under-actuated systems
- trajectory optimization
- parameter optimization
