    Edward L. Chupp works in the general area of  High Energy Astrophysics including Cosmic and Solar gamma-ray/neutron  Astronomy. He has been Principal Investigator for the Gamma-Ray Spectrometer experiments on the OSO-7 and the Solar Maximum Mission satellite missions, which made pioneering observations of solar flare gamma rays and neutrons, as well as on several balloon projects. He is the lead author of numerous papers on gamma-ray astronomy and a monograph that reviewed the field, with emphasis on experimental techniques. He has considerable experience in the analysis and interpretation of data from gamma-ray astronomy experiments. In addition, he has been thesis advisor to more than 10 graduate students, several of whom are currently making independent contributions to Solar Physics and Astophysics.

    Areas of Expertise

    Dr. Ryan has been involved in high energy astrophysics and solar physics research for over 30 years. His thesis research involved the development of a balloon-borne Compton telescope. From 1978 to 1982, he was a co-investigator on the UNH SMM Gamma Ray Spectrometer experiment. In 1982, he became a co-investigator with the COMPTEL experiment on CGRO. In 1988, he became a Co-Principle Investigator on the COMPTEL project. His scientific interests have focused on studies of the high energy emissions from solar flares. Recent projects have included a study of ground level neutrons for IBM, the development of CdZnTe strip detectors for γ-ray astronomy, and the development of a scintillating fiber neutron tracking telescope (SONTRAC). In addition, he is the Principal Investigator on the Mt. Washington and Durham neutron monitors, the BalloonWinds project to measure tropospheric with with a balloon-borne lidar sounder, UNH efforts to develop a hard X-ray polarimeter for solar flares, the development of a water Çerenkov telescope (MILAGRO) for detecting solar protons and neutrons above 4 GV and development of neutron and gamma detectors for homeland security. Dr. Ryan has also served on numerous NASA committees, including the most recent Solar Sentinel Definition Team.
