About Me

Hello! I am a CIFellows 2020 Postdoc working on legged robots in Prof. Aaron Johnson's Robomechanics Lab at Carnegie Mellon University. I completed my PhD at UC Berkeley in Prof. Ron Fearing's Biomimetic Millisystems Lab in May 2020 working on Salto, a small monopedal jumping robot.

I am passionate about sharing robotics and science with young students, and led my department's grad student outreach group during my PhD and helped develop virtual computer aided design lessons for middle school girls in Pittsburgh during my postdoc.

Outside of work, I enjoy hiking, collecting outdated laptops, and putting Matlab and PowerPoint to unusual and occasionally artistic uses.

Research Interests

Robots have the potential to be uniquely useful tools and teammates, but currently have trouble getting around in many environments. Cluttered living rooms, ladders, and other spaces humans easily navigate remain challenging for robots. Natural environments like intertidal zones, cliffs, and trees are even less accessible to robots. In many cases, robots are physically incapable of consistently traversing complicated terrain regardless of control scheme due to force and power constraints, uncontrolled mechanical modes like backlash and vibration, or insufficient control bandwidth. My research enables high-performance locomotion in robots and investigates the underlying science by concurrently designing mechanisms that exhibit reduced-order dynamics and advantageous energy flow with controllers that leverage these mechanisms’ natural dynamics. By improving robot locomotion, robots will be able to accompany humans wherever they go and even reach places humans cannnot.
