Biography

I am currently an Applied Science & Engineering Manager at Samsara advancing computer vision / deep learning / AI for improving the safety, sustainability, and efficiency of the operations that power the global economy.

Previously I led a team of applied scientists and machine learning engineers on Amazon's physical stores tech team that delivered the Just Walk Out cashier-less checkout technology. By building and deploying computer vision and deep learning to the cloud and to edge compute, we created a store where customers can simply take what they want and go! No lines, no checkout. Today these systems run in over 100 Just Walk Out stores operated by Amazon and third parties who license Amazon's technology.

I completed my Ph.D. in Computer Science at the University of Washington in Seattle with Professor Dieter Fox in Dec 2013. Before that, I obtained my B.Sc. in Computer Science at the University of British Columbia in Vancouver, BC.
