1992-2006 I was the coordinator of three European Networks and one INTAS Network.
I have supervised 25 PhD students.
I was Head of Department of Mathematics at York during the years 99-04, 05-07, 11-15.
My mathematical interests have varied over the years, ranging from string theory (in its early days) to integrable quantum field theory (especially Toda field theory), via gauge theories (monopoles and instantons). My current research concerns various aspects of Mathematical Physics, especially classical and quantum field theory and two-dimensional integrable quantum field theories with boundaries and defects.
A list of my publications and other articles can be found in the INSPIRE database
I am ready to supervise students interested in any aspect of classical and quantum integrable systems.
