I’m currently a software engineer at Microsoft. Previously, I was a graduate student under Prof. Naomi Fitter in the SHARE Lab at Oregon State University where I worked on assistive robots for older adults. I have previously worked with Prof. Heather Knight on expressive arm motion and Dr. Cristina Wilson on robot operator trust and confidence here at OSU. My undergrad was at the University of Washington where I worked under Prof. Siddhartha Srinivasa on assistive feeding.

In a complete theory there is an element corresponding to each element of reality. A sufficient condition for the reality of a physical quantity is the possibility of predicting it with certainty, without disturbing the system. In quantum mechanics in the case of two physical quantities described by non-commuting operators, the knowledge of one precludes the knowledge of the other. Then either (1) the description of reality given by the wave function in quantum mechanics is not complete or (2) these two quantities cannot have simultaneous reality. Consideration of the problem of making predictions concerning a system on the basis of measurements made on another system that had previously interacted with it leads to the result that if (1) is false then (2) is also false. One is thus led to conclude that the description of reality as given by a wave function is not complete.
