Research

I am broadly interested in theoretical astrophysics and cosmology. My research in astrophysics has focused on interstellar spinning dust grains and large molecules. As a cosmologist, I work on understanding the implications of various dark-matter candidates and initial conditions on cosmological observables, such as the cosmic microwave background, 21-cm tomography, and large-scale-structure surveys. I rely mostly on analytic calculations, and strive to devise efficient numerical methods when needed.
