Joseph Dwyer
Professor and Peter T. Paul Chair
cosmic-rays, gamma-ray astronomy
Joint Appointment with Department of Physics
PhD, University of Chicago

Joseph Dwyer received his PhD in physics from the University of Chicago in 1994, working on cosmic-ray astrophysics. He worked as a research scientist on gamma-ray astronomy and space physics at Columbia University and the University of Maryland before joining the faculty at Florida Tech in 2000. In 2002 he became interested in lightning physics and in 2003 helped establish that lightning emits bright bursts of x-rays. He has since made contributions to terrestrial gamma-ray flashes (TGFs), terrestrial electron beams (TEBs) in the inner magnetosphere, x-rays from laboratory sparks, and relativistic feedback discharges (aka dark lightning), helping establish the new field of high-energy atmospheric physics. Dwyer served as head of the Physics Department at Florida Tech before moving to the University of New Hampshire in 2014. He is now Professor and Peter T. Paul Chair in Space Sciences Space Science Center (EOS) and the Department of Physics at UNH.
