I am broadly interested in theoretical astrophysics and cosmology, with a focus on analytic work. 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 and large-scale-structure. I am also interested in gravity and gravitational waves, and have also worked on interstellar spinning dust grains and large molecules.

Teaching and pedagogical materials
