About Me

I am a Research Scientist at Facebook Reality Labs (FRL) Research. My research interests include machine learning, numerical optimization, computer graphics and vision. I received my Ph.D. degree from the Computer Science department at the University of British Columbia, supervised by Wolfgang Heidrich.
