My research interests primarily are in the areas of Quantum Field Theories (QFT) and their non-perturbative properties. Two well-known and common examples of non-perturbative properties are spontaneous (or dynamical) symmetry breaking and confinement. QFT defined through path integral quantization on discrete space-time Euclidean lattice provides a first-principles formalism to investigate their non-perturbative properties. This approach is popularly known as Lattice Gauge Theories. Specifically, I have worked on and have interest in the problems of lattice fermions and chiral symmetry, chiral gauge theories on lattice, non-perturbative properties of non-asymptotically free couplings (like the U(1) gauge coupling, Yukawa coupling and the scalar field quartic self-coupling), non-perturbative gauge-fixing, QCD spectrum, chiral regime of QCD etc.
