I am a 3rd and final year PhD student at INRIA Paris (Sierra Project team, led by Francis Bach). I am working under the supervision of Umut Simsekli and Alain Durmus.

Before that, I obtained an MSc in Mathematics from the University of Oxford, and a BSc/MSc from Ecole Polytechnique. More information about professional and academic experiences can be found in my CV.

Join our reading group on diffusion models I am co-organising a discussion-based reading group on generative models, diffusion models and related topics in Inria Paris, taking place once every 2-3 weeks. If you would like to join just send me an e-mail.

• Here is a selection of relevant articles to inspire presentations and discussions
• Here is a schedule of upcoming sessions and potential topics.
