Research Interests

I have worked on various topics in quantum field theory, mostly on the formal side, which include IR modifications of gravity, lattice chiral gauge theories, and AdS/CFT. Recently I have worked on dark matter phenomenology as well. At the current moment, I am focusing on 1/N corrections in AdS/CFT and its applications. More specifically, I am working on the 1-loop Witten diagrams in the AdS space and its renormalziations, and investigating various analytic properties of the loop diagrams in QFTs on the AdS background. I am also interested in various models of modifications of gravity including Horava-Lifshitz models, Einstein-Cartan theory with minimally coupled fermions and massive gravity in different dimensional space or geometric backgrounds, and I am investigating the possible implications of those models in cosmology.
