About

Starting in Summer 2025, I am an Assistant Professor at the College of Engineering & Computer Science (CECS) of VinUniversity. My current research interests are on generative models and optimization, with a focus on methodological/theoretical side.

Before joining VinUniversity, from 2023-2025, I was a Research Fellow at Mathematics Department of National University of Singapore (NUS), working with Soh Yong Sheng. Before that, in 2022, I was a postdoctoral researcher at Télecom Paris, working with Florence d’Alché, Gabriel Peyré and Remi Flamary on the applications of optimal transport to machine learning.

I obtained my PhD in 2021 within the Proba-Stat team of Département de Mathématiques d’Orsay and INRIA Parietal team, working with problems in high-dimensional statistics. I was very fortunate to be advised by Sylvain Arlot and Bertrand Thirion.

I spent a fair amount of time during my PhD for the developments of open-source software, and still code daily (though less than I want to). Check out Nilearn, hidimstat, and Benchopt for the open-source projects that I have been developing/contributing to.

At Binh’s AI Lab (BAIL), we are doing a mix of theory and algorithmic development, with focus on generative modeling and optimization.
