Brief description of current research:
Particle Physics Phenomenology:
I am working at the interface of experiment and theory, where I am investigating processes involving elementary particles at high energy (E >>1 GeV). In particular, I study the following subjects: Z and W physics, new gauge particles, the mechanism of spontaneous symmetry breaking and Higgs particle(s), supersymmetry, fourth generation, lepton number violation, neutrinos, and implications of all the above to present and future accelerators such as the Fermilab Tevatron, the CERN Large Hadron Collider (LHC) and the International Linear Collider (ILC).
