| Hey, I'm Andrew Friedman, currently a fourth year Astronomy Ph.D. student at Harvard University. I did my undergrad at UC Berkeley (Go Bears!) double majoring in Physics and Astrophysics, and I'm originally from San Diego, so I'm not yet used to this whole ice age phenomenon here on the east coast. As it is, I'm excited to be here at Harvard and in Cambridge. I'm currently working on my thesis project with Professor Robert Kirshner, with the goal of using Supernovae and Gamma-Ray Bursts (GRBs) as standardizable candles for cosmology, specifically to measure the expansion history and equation of state of the universe. The supernova aspect of the project uses infrared supernova data obtained with the fully robotic Peters Automated Infrared Imaging Telescope (PAIRITEL) P.I. Professor Joshua Bloom, UC Berkeley. The GRB aspect expands upon my previous work with Professor Ramesh Narayan and Professor Joshua Bloom, which focused on Gamma-Ray Burst (GRB) spectra and energetics and testing the potential applications of GRBs for cosmology. My work has been supported in part by the NSF through a National Science Foundation Graduate Research Fellowship., and will be supported by NASA through the Graduate Student Research Program (GSRP). For the GSRP project, I will collaborate with researchers at the NASA Goddard Space Flight Center in Maryland, including Dr. Neil Gehrels, the Principal Investigator of the NASA Swift Satellite, a dedicated space satellite for studying GRBs. |

MEDIA: Professor Robert Kirshner (my thesis advisor) and I were
interviewed at the 207th AAS Conference in Washington DC, Jan 11 2006 by Robert Irion of
Science magazine. Only one of us ("the President") is quoted, but the article
provides a good look at the recent excitement and controversy surrounding Gamma-Ray burst
cosmology. It appears in the January 20th issue of Science - Irion, R.,Astronomers Push and Pull Over Dark Energy’s Role in Cosmos, Science, 20 Jan. 2006, Vol. 311, pg. 316, (pdf)
