I am a scientist working on theoretical physics of elementary particles. My research field explores physical objects at tiniest distances accessible to modern science. We study basic forces existing in nature, structure of space and time, and events that occured at the very beginning of our Universe. I am involved in studies of particle interactions at the newly built Large Hadron Collider near Geneva, Switzerland. Our main objective is to discover the mechanism that gives mass to elementary particles and to look for new types of interactions, such as supersymmetry. For this purpose, I develop theoretical models describing in realistic detail both known particle interactions and expected new phenomena. Without such models, observations of new effects at the LHC will be difficult if ever possible. My work involves analytical calculations and computer simulations in quantum field theory, as well as multi-variate statistical analysis of diverse experimental data, notably development of widely used parametrizations of parton distribution functions by CTEQ collaboration. My research interests include elementary particle phenomenology in the Standard Model and beyond; perturbative computations and factorization methods in quantum chromodynamics; coordinated analysis of Standard Model and new phenomena at modern colliders My recent CV An elementary introduction to particle physics
