Dr Tommaso Rosati

Welcome! I am a Harrison fellow in the stats department of the University of Warwick.

From September 2024 I am supported by a Leverhulme Early Career Fellowship.

I study topics in probability and stochastic analysis: long-time properties of (singular) stochastic partial differential equations and scaling limits of particle systems.

Contact me: t.rosati@warwick.ac.uk.

Or in person: room 1.11 of the mathematical sciences building.

Office hours: 17:00-18:00 every Tuesday and 14:00-15:00 every Thursday (please write me an email first).

Teaching:

        • 2024/25 Brownian Motion (MA4F7/ST403).
        • 2023/24 Brownian Motion (MA4F7/ST403), and Stochastic PDEs (ST924).
        • 2022/23 Brownian Motion (MA4F7/ST403).

Outreach & other:

        • I recently wrote some lecture notes for a mini-course of stochastic PDEs: they can be found here.
        • "Randomness is natural - an introduction to regularisation by noise", in collaboration with H. Elad-Altman and A. Djurdjevac, snapshots of modern mathematics from Oberwolfach.
        • I helped revamp the Probability at Warwick website. Check it out here!
