Durrance has been involved in the flight hardware development, optical and mechanical design, construction, and integration of the Hopkins Ultraviolet Telescope and the Astro Observatory.
He has conducted research and directed graduate students at the Johns Hopkins University for the past 15 years.
He has designed and built spectrometers, detectors, and imaging systems, and made numerous spacecraft and ground-based astronomical observations.
He conceived and directed a program at Johns Hopkins University to develop adaptive-optics instrumentation for ground based astronomy.
He led the team that designed and constructed the Adaptive Optics Coronagraph, which led to the discovery of the first cool brown dwarf orbiting a nearby star.
He also a co-discoverer of changes in the planet-forming disk surrounding the star beta Pictoris.

His research interests include the origin and evolution of the solar system, the search for planets around other stars, planetary astronomy, atmospheric physics, nuclear physics, adaptive optics, spacecraft operations, and the origin of life.
He has published over 60 technical papers in professional journals covering these topics.

Durrance logged over 615 hours in space as a payload specialist and member of the crew of Space Shuttle Columbia for the STS-35/Astro-1 and Space Shuttle Endeavour for the STS-67/Astro-2 missions.
