• Within QCD I'm interested in using analytic methods to understand quark confinement and chiral symmetry breaking.
  
• I have studied QCD at high density where it is a colour superconductor.
  
• Supersymmetric versions of QCD are easier to solve than standard QCD and I have developed techniques to interpolate between those results and normal QCD.
  
• Most recently I have been using string theory as a tool to study QCD. Remarkably it turns out that QCD at strong coupling can be described by a string theory dual. Here are two Physics World articles I have written on the subject: article 1 & article 2 .
  
• Finally I've had a long standing interest in the possible role of strong dynamics in the higgs mechanism that breaks electroweak symmetry in the Standard Model. It may well turn out that the higgs boson is a strongly bound composite object.
