Research Interests

I am a theoretical astrophysicist. My interests range from the search for planets around nearby stars to the shape of the universe.

Over the past decade, the WMAP Satellite has been the main focus of my research. WMAP was successfully launched on June 30, 2001. The results from WMAP are described in a series of papers. The WMAP 2003 and 2006 parameters papers are currently the 4th and 10th most cited paper in the entire SPIRES catalog and the two most cited papers in physics published this millenium. Our seven year results paper is the most cited paper published in 2011 in physics and astrophysics. See this page for a list of my publications.

See this interview for a brief description of the WMAP results and see Mike Lemonick's book for the story of the WMAP satellite. My next major CMB project is the Atacama Cosmology Telescope (ACT)

I am involved in several large space and ground-based collaborations that are developing new technologies for cosmology and exoplanet science:

I am the Founding Director of the Center for Computational Astrophysics at the Flatiron Institute.

Here are links to a list of my recent and most-cited papers.
