About Me

I am currently a Researcher at Simons Institute (UC Berkeley), and a member of the Collaboration on Theoretical Foundations of Deep Learning. I've also been a Peng Tsu Ann Assistant Professor of Mathematics at the National University of Singapore for the last 3 years. Previously, I obtained my PhD in Statistics & Machine learning at the University of Oxford where I was advised by Arnaud Doucet, and Judith Rousseau. I was also a member of the OxCSML Group. Before starting my PhD, I graduated from Ecole Polytechnique in France with a major in Applied Mathematics and Financial Engineering.

I like to scale up things! My main research focuses on efficient learning at scale. My goal is to derive pareto-optimal algorithms for the pretraining and finetuning of large models. I am also broadly interested in:

  • Data: Synthetic Data Generation, Data Pruning, Data Augmentation
  • Trustworthy AI in the LLM era: Privacy, Hallucination, etc.
  • Real-world applications of AI: AI for Life sciences, AI for Decision science, AI for Education
