Personal: I live in New York, with my wife Erin, son Andrew and daughter Heidi.

Professional: Currently, I am an astronomer and a professor in the Department of Physics at NYU. I am a member of the Center for Cosmology and Particle Physics there. The bulk of my research focuses on the Sloan Digital Sky Survey. The image above shows a small section of the Universe mapped by this survey, where individual galaxies are each shown as a single point.
