Research 

Maria Ubiali is a member of the Department of Applied Mathematics and Theoretical Physics High Energy Physics research group and The Cambridge SUSY Working Group based at the Cavendish Laboratory.

Maria is a particle phenomenologist. Her main research interests include Quantum Chromo Dynamics and Beyond Standard Model phenomenology, the precise determination of the structure of the proton using machine learning techniques and processes involving heavy particles.
