James M. Ryan
Cosmic Ray/Solar-Terrestrial Physics
Joint Appointment Department of Physics
Ph.D., University of California, Riverside

Research Interests:

Terrestrial, solar, and astrophysical cosmic rays, neutrons and gamma rays.

I was the UNH project director for the COMPTEL experiment on the Compton Gamma-Ray Observatory. Now I am the Principal Investigator for the Durham and Mt. Washington neutron monitors and lead a research group in developing gamma-ray and neutron imagers for space applications and homeland security. I am also a Co-Investigator on the BalloonWinds experiment to measure tropospheric winds from a high altitude balloon as a demonstration project for a space borne Doppler Wind satellite mission. Other projects include the Milagro and HAWC ground-level TeV gamma-ray telescopes. I am the past chair of the Division of Astrophysics of the American Physical Society.

I am the thesis adviser for two graduate students working on Milagro solar particle data and development of a 1-20 MeV neutron imager for the inner heliosphere and homeland security.
