Biography
Professor Hickox is an observational astrophysicist with primary interests in supermassive black holes and the evolution of galaxies. He has a B.S. in Physics (2000) from Yale University and a Ph.D. in Astronomy (2007) from Harvard University. He held postdoctoral fellowships at the Smithsonian Astrophysical Observatory and Durham University in the UK, and joined Dartmouth College in December 2011. His research has been funded by NASA, the National Science Foundation (including a CAREER award), and an Alfred P. Sloan Research Fellowship.
