About Me

Since October 2023, I have been a CNRS researcher in the Quantum Information & Computation group at LaBRI (Université de Bordeaux).

Previously, I was a Quantum Postdoctoral Fellow at the Simons Institute (UC Berkeley) hosted by Umesh Vazirani and a Ph.D. student at IRIF (Université Paris Cité) advised by Frédéric Magniez and Miklos Santha.

Research Interest

My primary research interest is quantum computing. I study the impact of quantum mechanics on algorithm design and computational complexity theory. I have contributed to new quantum algorithms in diverse areas such as optimization, statistical analysis, streaming data, graph problems and cryptanalysis. I am also interested in new algorithmic and lower-bound methods for understanding the interplay between the computational resources available to quantum computers, with a particular interest in time-space tradeoffs.
