PhD in Mathematics of Information

I am a 4th year PhD student at the Cambridge Image Analysis group in the Department of Applied Mathematics and Theoretical Physics. I am also a member of the Cantab Capital Institute for the Mathematics of Information.

My research focuses on generative modeling, with a particular emphasis on diffusion models. Recently, I have become deeply interested in disentangled representation learning and the extraction of data manifold properties from pretrained generative models, including diffusion models and normalizing flows. Additionally, I have been exploring the fascinating area of Schrödinger Bridges.

If any of those topics sound interesting, reach out. I am always happy to chat!
