My resume.

Research interests: Healthcare Operations, Optimization, Learning & Uncertainty in Decision Making, Markov Models.


News

In the academic year 2020/2021, I will be applying to faculty positions in Operations Research departments and Business schools. I am also interested in postocs, both in the industry and the academic world.

During the summer 2020, I am joining the Supply Chain and Operations Technology team at Amazon Research in New York City.

In the Spring 2020, I was awarded the Deming Fellowship for my work on healthcare operations.


About me

I am a fourth-year PhD candidate in the IEOR Department at Columbia University. I work with my advisor Prof. Vineet Goyal and Prof. Carri W. Chan (Columbia Business School) on decision making under parameter uncertainty, with an emphasis on applications in healthcare.

Prior to joining Columbia, I graduated from Ecole Polytechnique in 2016 with an MS and BS in Optimization and Algorithms.

A few writings: a novel inspired from Brutus' life, one from Erostrate's life, an evening at the theater...
... and translations: a selection from Chekhov's novels, plays and articles (Oncle Vania, La chambre numéro six, La fiancée, Une plaisanterie, a few articles about theater) and Sergei Yesenin's short writings and poems.
