• Research Activities

  • California Institute of Techonology

    The current focus of the collaborative research between myself, Professor Michael Ortiz, and Professor Houman Owhadi is to apply the Concentration-of-Measure phenomenon to uncertainty quantification, specifically verification of engineering systems. Current funding is provided through the recently received PSAAP grant. Read more about Caltech's PSAAP Center.

  • Carnegie-Mellon University

    The focus of this past research was to develop a device that could enable haptic dexterity for users with C5/C6 spinal cord injuries with limited or no use of their hands. The body's electrical signals were recorded through EMGs by the flexing of bicep muscles to trigger pinching motions in the hand exoskeleton human-machine interface. Users showed considerable pinching dexterity when using the device.
