About

I am a postdoctoral researcher at the Technical University of Munich, at the Department of Computer Science within the chair of Decision Sciences & Systems (You should know this already if you are viewing this page!). My research interests are primarily (convex) optimization and its applications, with an emphasis on electricity markets, efficiency of mechanisms, and learning (to bid) in auctions.

I have a multidisciplinary background: I obtained a BSc in Mathematics & Physics (Joint Honours) at McGill University, an MSc in Economics at the London School of Economics, and a PhD in Mathematics at again McGill University - the latter under the supervision of Prof. Adrian Vetta.

You may find my personal webpage here, which also contains my CV.
