Bio
I joined the Department of Mechanical, Industrial and Aerospace Engineering at Concordia in August 2015. Prior to that, I was a post-doctoral fellow at the Applied Optimization Lab at the University of Toronto working with Timothy Chan. I obtained my PhD and MASc degrees in Industrial Engineering from the University of Toronto, supervised by Chris Beck at the Toronto Intelligent Decision Engineering Lab. An article about my first year at Concordia has been featured in the Concordia Now newsletter.
