Research

A large number and variety of ongoing and upcoming experiments are mapping the entire structure of the observable universe, which is establishing the experimental foundation for the emerging field of density perturbation phenomenology -- learning fundamental physics from density perturbation maps. Quantum gravity is believed to be the theoretical framework for the creation of the seeds of these structures in the early universe. My current research interest is to understand the connections between the theories and experiments in this field, and use them to probe fundamental physics in the early universe.
