Ali Aouad

My research primarily focuses on algorithms under uncertainty and data-driven decision-making with applications in supply chains, market design, and public sector issues. A central objective of my work is to improve the efficiency and equity of digital marketplaces, particularly using assortment and matching optimization. My second line of research aims to develop evidence-based policies in the areas of cultural management and food security by studying the interplay of digitization processes and individual preferences.

I am an associate editor in Operations Research and Management Science. In 2018-2019, I was an applied scientist in the Marketplace Optimization group at Uber Technologies.  I worked and consulted for the Matching Science team to design and experiment with new matching and pricing algorithms. I received a PhD in Operations Research from the Massachusetts Institute of Technology (MIT) in 2017, where I collaborated with Profs. Vivek Farias, Retsef Levi, and Danny Segev. Before MIT, I earned an MS in Applied Mathematics from the Ecole Polytechnique (Paris) in 2013.  I was born in Meknes, Morocco.
