About Me

Wandering Rehabiliation Engineer

I believe engineering and art, when applied in the right way, are the greatest devices towards the betterment of the human condition. To that end, I apply my skills in fields like robotics and machine learning in different walks of life - Rehabilitation, Agriculture, Environmental Protection.

Traveling, meeting different faces of humanity and the cultures we have concocted across the globe is always a source of joy. In my travels, I 've had the fortune of working on robotics research on 3 continents with the finest of folks - engineers, artists, prosthetists, surgeons, philosophers. I have worked as a researcher in 2 world-class rehabilitation hospitals and a bio-medical company.

I delved into powered prostheses control using natural body movements and vision as part of my Ph.D. research at the University of Washington, Seattle. As part of the engineering R & D at the Rehabilitation Institute of Chicago, I worked on the hardware design of myoelectric control of prostheses. These designs were spun off to create CoApt, one of the most advanced prosthetic control.

In my mid-twenties, I became fascinated by decentralized algorithms and modular robots for mimicking cellular biology. My Masters' thesis at the University of Colorado explored their application for assembling complex organisms and even self-repair and regeneration.

My current purpose is to enable mobility in developing nations through accessible assistive devices.

Not all who wander are lost.

What's Espérance

Espérance Creations is a vehicle for my hopeful fantastical dream, a ‘khayali pulav’. Hope of not just sounding exotically french and cool, but also of creating a better world through technology and engineering. Espérance pour un monde meilleur.
