Brian Espey obtained his undergraduate degree (BA Mod) in physics from Trinity College Dublin, Ireland in 1984. He obtained a PhD in astronomy from the University of Cambridge, England, in 1990 before going on to work as a Royal Society European Science Exchange Fellow in Leiden, The Netherlands. Prior to joining the Hopkins Ultraviolet Telescope project in January 1994, he worked as a research associate at the University of Pittsburgh for three years. As well as being a member of the HUT science team with interest in quasar emission and absorption line systems, he has also been selected by NASA to be a guest investigator on the Astro-2 mission. He has published several refereed papers.
Espey currently holds the position of Research Associate Scientist at The Johns Hopkins University with responsibility for the guest investigator programs, and also an adjunct Research Assistant Professorship at the University of Pittsburgh.
The aim of his HUT guest investigator project is to study the ultraviolet continuum and emission line properties of symbiotic stars in order to learn about the properties of mass loss in these systems. Symbiotic stars, as their name suggests, are actually binary star systems consisting of a very hot white dwarf and a cool red giant in orbit about each other at a distance comparable to the distance from the Earth to the Sun.
