I am a theoretical physicist interested in astrophysics and cosmology, and specialize in the study of the stuff between galaxies (which constitutes the majority of the mass in the Universe).  In particular, I study the properties of this matter and its evolution from the infant Universe up until today.  I have also investigated the properties of the first galaxies, the large-scale structure of the Universe, the nature of the dark matter, and radiative transfer algorithms.  Click here for additional details on my research.

I am currently a NASA Einstein Postdoctoral Fellow at the University of California, Berkeley in the Astronomy Department.   For my CV, click here.
