My research interest concerns computational aspects of quantum field theories, mainly
Lattice Gauge Theory.
My works in lattice
Quantum Chromodynamics (QCD) mainly focus on large scale simulations to understand
the structures and interactions of subatomic particles, known as hadrons.
A comprehensive understanding of the hadron
phenomenology as a consequence of the chiral symmetry breaking is a
challenge in particle physics. Lattice QCD is the only
known way to understand it from the first principle with controlled systematics. With advances in petascale computing
and better algorithms, full QCD
simulations are becoming increasingly accessible at adequate
volumes and small enough lattice spacings, and at quark masses approaching their physical values. With all these recent developments, lattice gauge theory can provide
precise results for various physical observables in nuclear and
