Akshay Venkatesh has received a Fields medal at this year's International Congress of Mathematicians in Rio de Janeiro. In the first interview we asked him what it feels like to win a Fields Medal, and what he enjoys most about doing mathematics.

We really enjoyed Venkatesh's Fields Medal lecture where he gave an overview of his recent work. In this second interview we have tried to capture a flavour of the some of the maths it involved.
