Research Interests
I am interested in a variety of topics in theoretical physics and cosmology, including general relativity, gravity theories, dark energy, inflation, and primordial density perturbations. My research focuses on cosmological observational constraints on modified gravity theories. Cosmological data from a wide range of cosmological observational probes allows us to test theories about the growth of structures in our universe.Short Curriculum Vitae
