About Me
I am a second-year PhD student supervised by Prof. Graham Cormode and Prof. Carsten Maple (WMG). Before starting my PhD I graduated with a first-class MEng in Discrete Mathematics here at the University of Warwick.
During the Summer of 2022, I was a research intern at Meta AI supervised by Pierre Stock and Alexandre Sablayrolles.
Research Interests
My research interests lie at the intersection of computer security, data privacy and machine learning. I am mainly interested in the area of privacy-preserving machine learning (PPML) which seeks to develop ML algorithms to learn privately and securely from data which is often highly distributed. This is a wide-area and includes topics such as Differential Privacy (DP), Federated Learning (FL) and Federated Analytics.
