My professional activity is summarized in my CV.  A brief description is given below.


I have worked on a wide spectrum of subjects, ranging from formal questions in field theory, to phenomenology of particle physics and cosmology. My published work addresses questions on:

  • Phase transitions and the exact renormalization group
  • Beyond the Standard Model physics
  • Dark matter and dark energy
  • Inflation and supersymmetry
  • Phase diagram of QCD and heavy ion collisions
  • Brane physics (phenomenology and cosmology)
  • Inhomogeneous cosmology
  • Applications of the AdS/CFT correspondence

A list of my publications, as well as a citation summary, can be obtained from INSPIRE. My most cited works are on the exact renormalization group, leptogenesis, and cosmology in theories with extra dimensions. 

My current research interests include the nature of dark matter and dark energy, the calculation of the nonlinear spectrum of the distribution of matter in the Universe and the stability of the electroweak vacuum.
