Events

• I am  the University of Reading node for the GWNT seminar, which receives financial support from the LMS and others. The next seminar is scheduled to take place at the University of Oxford soon!

Postdocs and PhDs

• I am very happy to support postdoctoral fellowship applications hosted at the University of Reading, such as those through Marie-Curie, EPSRC, Royal Commission for the Exhibition of 1851, LMS, Leverhulme, etc. 

• I am also very happy to support PhD applicants to the University who are interested in number theory, arithmetic geometry, or any of the other topics relevant to my work.
