Research Interests

Bloom's research group focuses on understanding the origin of high-energy transients, particularly gamma-ray bursts, and using such transients as astrophysical probes. Bloom is principal investigator of the largest robotic infrared telescope dedicated to the study astrophysical transients. He is also co-investigator of an NSF-sponsored project to build a cyberinfrastructure for time domain astronomy.


Bloom received a PhD in Astronomy and Astrophysics from Caltech in 2002 after receiving an M. Phil in Astronomy in 1997 from Cambridge University, England. He graduated from Harvard College magna cum laude with a double AB in Astronomy & Astrophysics and Physics. He is a Sloan Research Fellow.
