March 2024. I'm very happy to say that the UKRI AI Hub on Probabilistic Artificial Intelligence has received £9.5m funding for the next five years. PhD positions are now open at Warwick, see here, these positions can cover international fees with a full scholarship. Other PhD positions at the partner universities are also being announced and will appear here. Postdoc positions are expected to be advertised soon and will appear here when they are.

I've also been awarded a Leverhulme Trust Research Project grant and will soon be advertising a 3-year postdoc position to work on this project. The project involves analysing robustness and uncertainty quantification of variational problems on graphs that come from semi-supervised machine learning problems. I'm particularly keen to develop methods that work for rare-events and unbalanced classes. The post will be advertised soon and you can contact me for informal inquiries.
