Research

My research is is general about using fundamental concepts of mechanics for design and control of novel robots and mechanisms. More specifically, I am focused on design and control of robotic legs for maximum efficiency, stability and robustness. In this way, I extensively use tools such as optimization, nonlinear control theory, and biomechanics to achieve novel hardware designs and control paradigms.

Areas of Research

Design and Control of Legged Robots

Wearable Robots

Actuators
