His research interests include dark matter particle production in the early universe and its detection today; precision cosmology and dark energy; neutrino physics in the early universe and supernovae; galaxy formation theory and statistics; primordial nucleosynthesis; and gamma ray bursts. A candidate dark matter signal was detected in 2014 with space telescopes using techniques he discovered with his colleagues in 2001. There will be dedicated follow-up NASA sounding rocket missions to look for the signal in 2018 to 2019. Dr. Abazajian earned his Ph.D. and M.S. in physics from the University of California, San Diego, and his B.S. in Physics from the University of Houston, University Park.
