My research lies in the fields of optimization and stochastic modeling, and focuses on the design and performance analysis of algorithms with applications to operations management. I am broadly interested in resource allocation problems in connection with choice modeling, revenue management, and matching markets.

I received a PhD in Operations Research from Massachusetts Institute of Technology (MIT), where my advisors were Profs. Vivek Farias and Retsef Levi. Before MIT, I earned an MS in Applied Mathematics from the Ecole Polytechnique, in Paris. I grew up in Meknes, Morocco.

Alongside academia, I have worked and consulted for technology, quantitative finance and management consulting firms. Before joining LBS, I spent a year at the Marketplace Optimization and Data Science Group at Uber Technologies (San Francisco), where I contributed to the design and implementation of new algorithms that improve the cost efficiency of the matching platform.
