I am a professor at
The Ohio State University
Department of
Astronomy in Columbus, Ohio.
I am an observationally oriented theorist and work mainly on
the formation of galaxies, large scale
structure, and high redshift objects.
I have been on the faculty at Ohio State since January, 1995. Prior to that, I was an undergraduate at Yale University, a graduate student at Princeton University, a postdoc at Cambridge University, and U.C. Berkeley, and a long term member at the Institute for Advanced Study. For details, see my c.v.
To find out more about my astronomical research, you can read the brief description here or check out my publications and recently submitted articles. A lot of my research involves the Sloan Digital Sky Survey (SDSS), for which I am presently the Collaboration Spokesperson. I am also the Project Scientist for SDSS-III, a six-year program of four surveys that will use the SDSS facilities to investigate new scientific areas.
Since 2004, I have been collaborating with MacArthur Award winning artist Josiah McElheny on the design of cosmologically inspired sculptures. You can read more about that and find some pictures here. I was also a science consultant for the film Dark Matter, an independent film written by Billy Shebar and Chen Shi-Zheng and starring Liu Ye, Aidan Quinn, and Meryl Streep.
You can also look here for some of my less serious treatments of cosmology and astrophysics, the most infamous of which is The Dark Matter Rap (lyrics).
