Dr. Green's research is focused on the design, development and use of space instrumentation for astrophysical studies, particularly ultraviolet astronomy. He was the Principal Investigator for the Cosmic Origins Spectrograph on the Hubble Space Telescope, designed and built the spectrograph for the Far Ultraviolet Spectroscopic Explorer, and has been a PI or Co-I on a sounding rocket program for 19 of the last 22 years. He recently submitted a proposal for a Small Explorer mission that will provide the first imaging capability at the shortest wavelengths in the far ultraviolet. His observational focus is on the intergalactic medium, the galactic/IGM interconnection, and the interstellar medium. His theoretical focus is on studies of the very early universe.

ASTR 2020 - Space Astronomy and Exploration
Covers physical principles of performing astronomy from space for science and exploration. The basic design of launch vehicles and spacecraft, orbital dynamics, and instruments will be described in the context of specific space missions (e.g. Hubble Telescope, Mars rovers) as well as prospects for future space observatories in orbit and on the Moon.
ASTR 5760 - Astrophysical Instrumentation
Covers the fundamentals underlying the design, construction and use of instrumentation used for astrophysical research ranging from radio-wavelengths to gamma rays. Topics include Fourier transforms and their applications, optical design concepts, incoherent and coherent signal detection, electronics and applications, and signal acquisition and processing. Department enforced prerequisite: senior level undergraduate physics.
