Research Description

I mostly work on dynamics of gauge theories with applications to QCD, theoretical lattice field theory and mathematical physics. My interests to date included: Gauge theory dynamics, QCD, Resurgence theory and its applications to QFT and quantum mechanics, Picard-Lefschetz/resurgence theory of path integration, Supersymmetry on lattice, Lattice gauge theory, Large-N volume independence, Eguchi-Kawai reduction, Orbifold-orientifold equivalences, Supersymmetric gauge dynamics, Classification of topological excitations (magnetic monopoles, magnetic and neutral bions, semi-classical renormalons) and confinement mechanisms.
