About me

I’m currently a researcher in the group of Omar Fawzi at the LIP, ENS de Lyon.

I received my Ph.D. degree in July 2022 from ENS de Lyon, advised by Professor Omar Fawzi. Before that, I earned my B.S. degree in Computer Science from Hanoi University of Science and Technology and my M.S. degree in Computer Science from ENS de Lyon.

My research focuses on some topics in computational complexity theory, additive combinatorics, and quantum information theory. In particular, I am mainly interested in the asymptotic spectra theory, the Shannon capacity of hypergraphs, the capacities of quantum channels, and quantum error correction.
