I am currently a visiting assistant professor at Cornell Tech as part of the Cornell School of Operations Research and Information Engineering. I received my PhD in Operations Research in 2020 from Columbia University where my advisor was Vineet Goyal. Before that, I graduated from Ecole Polytechnique (Paris) with an MS and BS in Applied Mathematics.


I am broadly interested in decision-making under uncertainty where I aim to develop optimization models and algorithms to address a wide-range of operational problems. My current research focuses on the design of robust and efficient algorithms for sequential dynamic optimization problems under uncertainty with applications in revenue management, facility location problems and matching markets.
