Research Interests:

Broadly speaking, my main interests are in theoretical astrophysics, high energy physics and cosmology. I have worked on large scale structure, the intergalactic medium, gravitational lensing, extra-solar planets, gravitational waves, inflation, cosmological soft theorems, dark matter, dark energy, effective field theory for hydrodynamics and black hole perturbations. You can find my publications at the astro-ph, hep-th, hep-ph and gr-qc archives.

Math Education:

This is a Math afterschool program for Kindergarteners to Fifth Graders in Harlem - the Reading Team Math Program.


A code for computing velocity two-point correlations, and the associated magnitude covariance for standard candles (such as supernovae). The code also contains portions useful for computing power spectrum, growth factor and cosmic distances.


A series of 3 introductory lectures on cosmology aimed at undergraduates.
