I'm a third year PhD student at the University of Cambridge, supervised by Professor Steve Young at the Dialogue Systems Group. I was previously a Machine Learning Consultant at VocalIQ, where I collaborated with Diarmuid O Seaghdha and Blaise Thomson

My research is currently focused on belief tracking in dialogue, where I am interested in moving towards building open-domain dialogue state tracking models. I am also interested in deep learning, natural language processing, Bayesian nonparametrics, unsupervised and semi-supervised learning.  

I completed my Master's thesis at the Cambridge Machine Learning Group, where I worked on Kernel Structure Discovery for Gaussian Process Classification with Professor Zoubin Ghahramani. Prior to that, I graduated from the Cambridge Computer Science Tripos, where my final year project with Dr Sean Holden focused on semi-supervised learning.
