I work as a research scientist at Facebook Reality Labs on neural interfaces. My team is hiring, reach out:


I graduated with a PhD in May 2015 from the Dynamic Graphics Project in the University of Toronto’s Computer Science Department. My supervisor was Ravin Balakrishnan (Computer Science). My committee was composed of Daniel Wigdor (Computer Science), Derek Reilly (Computer Science) and Bruce Barton (Drama).
