The unifying theme of my research is the study of nonperturbative
phenomena in particle physics. I intend to work towards building a detailed
qualitative and quantitative picture of low energy QCD, but perspectively also
to study subtle nonperturbative effects in electroweak theory and beyond.
I view the use of lattice regularization as one of the most important tools
for progressively achieving these goals. Consequently, various aspects of my work
relate to subfields such as lattice field theory, lattice QCD, QCD vacuum
structure, hadronic physics, critical phenomena and computational physics.
I have also worked in the area of heavy ion phenomenology. The current
source of excitement in my work is the study of QCD vacuum structure using new
methods motivated by the recent availability of lattice chiral fermions.
