I lead the Spatial Intelligent System (SPINS) Lab at University of Manitoba (UM). Prior to UM, I was a Machine Learning Engineer at Apple and then a Research Scientist at Meta Reality Labs. I got my Ph.D. degree from Simon Fraser University in 2020, supervised by Dr. Ping Tan. During my Ph.D., I had spent wonderful times as a research intern at Adobe Research with Dr. Oliver Wang and Microsoft Research with Dr. Lu Yuan.

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.
