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. An updated list of my publications is available on my Google Scholar page.

Teaching

I regularly teach two courses:
INDU6311: Simulation (graduate course in the Industrial Engineering program)
and
INDU480: Cases in Industrial Engineering (4th year case-based course)

Both courses are based on active learning and experiential learning principles. In INDU6311, the students work on projects with real partner organizations; in INDU480, the students work though case studies written based on past real projects. I believe that most students learn the most through application of concepts, theory and algorithms to real problems.

High School Outreach

I am a co-founder of TORCH, an annual one-day free contest held in March that aims to introduce high school and CEGEP students to operations research. TORCH is currently on hold due to COVID19.
