Hi! Welcome to my homepage. Allow me to say a couple words about myself...

I recently joined Gordon Wetzstein's Computational Imaging group at Stanford University as a Banting Postdoctoral Fellow. Before that, I received my Ph.D. in Computer Science at the University of Toronto under the supervision of Kyros Kutulakos in 2016, along with an M.Sc. in 2009. I took a break from Toronto in 2011 to be a visiting student with the MIT Media Lab's Camera Culture group led by Ramesh Raskar. I also completed an undergraduate degree in honours Computer Science and Mathematics from the University of British Columbia in 2007 under the supervision of Abhijeet Ghosh and Wolfgang Heidrich, and worked for various companies including NVIDIA, EA, and MDA.

I spend a lot of time thinking about computational imaging, a field that combines optics, electronics, and processing in new and interesting ways to capture and display visual information. In particular, I'm interested in using programmable lights and cameras to analyze the world around us.

My work was the recipient of a couple of runner-up best paper awards at ICCV 2007 and CVPR 2014, and best demo awards at CVPR 2015 and ICCP 2015. I was also a co-oraganizer of CVPR 2016's workshop on Computational Cameras and Displays, and taught a course on the subject at SIGGRAPH 2014. My research is supported by the Banting Postdoctoral Fellowships program administered by the Government of Canada.
