Omar El Housni is currently a Visiting Assistant Professor at Cornell Tech in Operations Research and Information Engineering.

His research revolves around decision-making under uncertainty where he aims to design robust and efficient algorithms for a wide-range of dynamic optimization problems with applications in revenue management and matching platforms. Omar spent few internships as a research and data scientist at Amazon and Uber where he contributed to the design and implementation of data-driven optimization models for matching and retailing platforms. 

El Housni’s holds a Bachelor’s degree in applied mathematics from École Polytechnique (France), and a Master of Science and a Ph.D. in Operations Research from Columbia University.
