deep learning, deep generative models, probabilistic inference, neural network verification

I am a final year DPhil student in the AIMS centre for doctoral training at Oxford supervised by Prof. M. Pawan Kumar and Prof. Yee Whye Teh. I am interested in advancing the state-of-the-art in Deep Generative Models, and developing new architectures and applications for them. During my DPhil, I’ve worked on distributed Bayesian learning, improving the design of inference networks, an importance component of amortized inference, as well as developing a new framework for neural network verification (under review).
