I am currently a research scientist at MIT's LIDS working in Munther Dahleh's research group. I am broadly interested in algorithmic economics, computational statistics, and opti­mization.

I completed my PhD in Computer Science at Harvard University in 2019, advised by Edoardo Airoldi and David Parkes. I received my M.S. in Computer Science from ENS Paris in 2011, and my M.S. in Probability and Statistics from Université Paris-Sud in 2010.
