Introducing John Gizis

This week features John Gizis. He is a professor in the Department of Physics and Astronomy at the University of Delaware in the USA. Instead of studying extremely distant luminous objects  with our most moderrn telescopes, he studies dim, nearby stars— think M, L, T and Y dwarfs. Objects at 100 parcsecs are uncomfortably distant in his opinion. When he started graduate school in 1992, nearby M dwarfs were considered uninteresting, but now they are fashionable thanks to the possibilty of detecting habitable  planets. He has also been fortunate to see the study of brown dwarfs go from searches for hypothetical objects to an active field of research. He considers himself an optical/infrared observational astronomer but he has ventured into the ultraviolet and X-rays from time to time.  He thinks he is fortunate to have the best job in the world and enjoys having the opportunity to teach both physics and astronomy.  The rest of the year, he is @johngizis, tweeting about astronomy and sports.
