James Lowenthal

James Lowenthal received his bachelor's degree from Yale College and a doctorate from the University of Arizona.

His research interests include: high redshift galaxies, Lyman Break galaxies; Starburst galaxies; MM and Submm galaxies; galaxy formation and evolution; QSO absorption line systems; QSO host galaxies; and ultra-faint radio sources.
