Research in theory and phenomenology of strong interactions and its application to electromagnetic and weak interactions of hadrons in the energy range of a few GeV. Main subjects are effective interactions in the light-quark systems, polarized photo- and electroproduction of mesons, QED radiative effects in electron scattering and theory of muon beam cooling.
Leader of a project on computing QED radiative
effects for JLab experiments and integrating the results into data
analysis procedures. Co-spokesman of experiment JLab E04-116 to
assess a role of two-photon exchange from electron vs positron
scattering comparison in CLAS. Co-spokesman of
LIPSS
experiment that looks for signatures of axion-like particles using
JLab Free-Electron Laser. Theory and modelling
of muon cooling for a Muon Collider, in collaboration with Muons, Inc. Theoretical support for design of Electron-Ion Collider.
