The Self

I'm a theoretical physicist at Caltech in sunny Pasadena, California. My research interests include theoretical aspects of cosmology, field theory, and gravitation. I want to learn about fundamental physics by studying the structure and evolution of the universe. These days I'm especially interested in inflation, the arrow of time, and what happened at or before the Big Bang. I've done a bunch of work on dark matter and dark energy, modified gravity, topological defects, extra dimensions, and violations of fundamental symmetries.

I recently finished writing a popular-level book on cosmology and the arrow of time: From Eternity to Here: The Quest for the Ultimate Theory of Time, which I expect all of you to buy. I previously wrote a graduate textbook, Spacetime and Geometry: An Introduction to General Relativity, and recorded a set of lectures on cosmology for the Teaching Company. I started blogging back in 2004, and keep it up to this day with the help of several friends at Cosmic Variance.

Here are distinct pages covering the various ways academics like to keep busy:

Stuffy Official Bio

Sean Carroll is a Senior Research Associate in Physics at the California Institute of Technology. He received his Ph.D. in 1993 from Harvard University, and has previously worked as a postdoctoral researcher at the Center for Theoretical Physics at MIT and at the Institute for Theoretical Physics at the University of California, Santa Barbara, as well as on the faculty at the University of Chicago. His research ranges over a number of topics in theoretical physics, focusing on cosmology, field theory, particle physics, and gravitation. Carroll is the author of From Eternity to Here: The Quest for the Ultimate Theory of Time, a popular-level book on cosmology and the arrow of time. He has also written a graduate textbook, Spacetime and Geometry: An Introduction to General Relativity, and recorded a set of lectures on cosmology for the Teaching Company. Carroll has been awarded fellowships from the Sloan and Packard foundations, as well as the MIT Graduate Student Council Teaching Award and the Villanova University Arts and Sciences Alumni Medallion. Carroll is a contributor to the blog Cosmic Variance. He lives in Los Angeles with his wife, writer Jennifer Ouellette.

My worldline

Until Fall 2006 I was on the faculty of the Physics Department and Enrico Fermi Institute of the University of Chicago. Before that I was a postdoc at the Institute for Theoretical Physics at the University of California in Santa Barbara, a postdoc at the Center for Theoretical Physics at MIT, a graduate student at the Harvard-Smithsonian Center for Astrophysics, and an undergraduate at the Department of Astronomy and Astrophysics at Villanova University. Before even that I attended Pennsbury High School, where my partner Bill Koehler and I came in second place in the state debate championships on a highly controversial 3-2 decision. Still haven't quite gotten over that.

To figure out where I might be in the future, check my schedule under activities.

By far the best way to reach me is by email: seancarrollatgmaildotcom, suitably decoded. I usually don't even pick up my phone, so there's not much point in calling.

If you are interested in becoming a student or postdoc at Caltech, please feel free to contact me by email. I am happy to talk about Caltech, although the actual application process is fairly formalized: prospective undergraduates go here, graduate students here, and postdocs here.

Unfortunately, I am not able to help with questions about physics, your theory of the universe, and so on. There just isn't enough time. I recommend checking out any of the various online discussion forums devoted to that kind of thing.

Unsolicited compliments, on the other hand, are always welcomed.
