My research lies at the interface between particle physics and cosmology, focussing on Tera Electron Volt scale physics.
My main contributions to this field have been:
  • to reconcile the existence of extra spatial dimensions with standard Friedmann cosmological expansion.
  • to propose the lightest Kaluza-Klein particle as a viable dark matter candidate.
  • to study the nature of the electroweak phase transition in various extensions of the Standard Model and the consequences of a modified cosmological expansion at the electroweak epoch.
  • to show that detection of a stochastic background of Gravity Waves at the space-interferometer LISA could be a major experimental implication of the Randall-Sundrum model.
  • I have been particularly interested in the possibility of probing early universe phase transitions with upcoming gravity wave experiments and I have been for instance advertising the relevance of LISA for electroweak scale physics.
  • I have been involved in analytic calculations of the gravity wave spectrum produced during first order phase transitions.
  • More recently, I have also been working on collider phenomenological studies. I have studied the prospects for multi W gauge boson production at LHC from the pair production and decay of new heavy quarks like heavy bottom quarks.
  • As far as dark matter is concerned, I have also investigated the case of heavy Dirac neutrinos and contributed to review chapters in the book "Particle dark matter".
