Some of my recent research interests include:

  • Connections between 2-dimensional Arakelov geometry and the new theory of higher adeles on arithmetic surfaces. This is a crucial part of the long term project of generalising Tate's thesis to arithmetic surfaces.

  • Diophantine geometry.

  • Higher dimensional Arakelov geometry: analogies between classical intersection theory of algebraic varieties  and arithmetic intersection theory.
