My primary research interests are in the areas of algorithm design and dynamic optimization with applications to retail analytics and matching platforms. My research spans two major themes: (1) customer choice modeling in operational contexts, and (2) dynamic resource allocation problems related to online platforms and networks.
I received a PhD in Operations Research from Massachusetts Institute of Technology (MIT), where my advisors were Profs. Vivek Farias and Retsef Levi. I was also very fortunate to collaborate with Prof. Danny Segev. Before MIT, I earned an MS in Applied Mathematics from the Ecole Polytechnique, in Paris. I grew up in Meknes, Morocco.
Before joining LBS, I spent a year in the Marketplace Data Science group at Uber Technologies in San Francisco. I worked and consulted with the Matching Science team to design and implement innovative algorithms and product features, improving the efficiency of the platform.
