Biography
Dmitri Tsybychev is an Associated Professor at Stony Brook University. He got his Ph. D. From University of Florida, Gainesville in 2004. He participated in CDF and DZero experiments at Tevatron proton antiproton collider at Fermi National Laboratory. He joined the ATLAS experiment in 2008, which along with CMS experiment in 2012 made a historic discovery of the Higgs boson.

Research Statement
My primary research interests concentrate on studies of fundamental particles and their interactions, conducted at highest energy and intensity particle colliders. I am pursuing studies of processes well predicted by the Standard Model (SM) of particle physics and searches for new physics in leptons, jets, including jets originating from heavy flavor quarks, and missing transverse momentum (MET) signature. My long term physics goal is to understand the mechanism responsible for symmetry breaking of the electroweak sector of SM through the study of scattering of longitudinally polarized W bosons and study of the Higgs boson properties. To that extent, I am currently working on the ATLAS Experiment as members of ATLAS collaboration, a large international group of physicists collecting data from proton-proton collisions at center-of-mass energies of 7-14 TeV, the highest collision energy in the world at CERN’s (European Center for Nuclear Research) Large Hadron Collider (LHC) near Geneva, Switzerland. I became a member of ATLAS collaboration upon joining the faculty at Stony Brook University. I am an expert in the charged-particle tracking devices based on silicon semiconductors, which are of the vital importance for such research. Earlier, as a member of the D0 collaboration, at Fermi National Laboratory, I studied physics of B meson decays, with the aim of understanding asymmetries in matter-antimatter behavior as well as place constraints on new physics phenomena.
