About Me

I am currently a Researcher at Simons Institute (UC Berkeley), and a member of the Collaboration on Theoretical Foundations of Deep Learning. Previously, I obtained my PhD in Statistics & Machine learning at the University of Oxford. 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 (MSc and Engineering Diploma), I also have a MSc in Quantitative Finance from Paris VI University.

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 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
