Research
Read research overview

At present, my machine learning interests are centred around distributed, efficient and collaborative machine learning. In particular, I have a great affinity towards paradigms such as federated learning and neural network compression, and the interplay this has with optimisation theory. Generally speaking, the motivating factor for this is that I am circumspect towards the promise of centralised machine learning paradigms, which require enormous amounts of data and computational resources to achieve their state-of-the-art performance. Instead, I believe that there is much benefit to be derived from investigating alternate paradigms that can scale while promoting privacy inherently, supported by sound mathematical foundations.

If you find any of my research interesting, or you would like to collaborate on any ideas, please do not hesitate to reach out.
