Employment: Post-doctoral research scientist, Columbia University, 1993 – 1995; Research associate, University of Maryland, 1995 – 2000; Lecturer, University of Maryland, 1999; Faculty in Department of Physics and Space Sciences, Florida Tech, 2000 – present; Director of the Geospace Physics Laboratory (GPL), Florida Tech, 2007 – present; President of the Faculty Senate at Florida Tech, 2010 – 2011

Memberships: AGU member since 1995; URSI member Commission H.

Awards: Florida Tech President’s Award for University Excellence, 2010; Florida Tech Faculty Excellence Award in Research, 2003; NSF CAREER Award, 2002; The University of Chicago, Enrico Fermi Institute Nathan Sugarman Award for Excellence in Research, 1991; NASA Graduate Student Researchers Program grant recipient, 1988 – 1991.

Publications: Author and coauthor of 96 peer-reviewed publications, 47 in AGU journals.  Most important work includes establishing that rocket-triggered lightning emits x-rays and investigating the characteristics of these energetic emissions (Dwyer, J. R., et al., Energetic Radiation Produced During Rocket-Triggered Lightning, Science, 299, 694, 2003); developing the relativistic feedback mechanism (Dwyer, J. R., A fundamental limit on electric fields in air, Geophys. Res. Lett., 30, 2055, 2003); demonstrating that long laboratory sparks in air emit x-rays (Dwyer, J. R., et al., X-ray bursts produced by laboratory sparks in air, Geophys. Res. Lett., 32, L20809, 2005); helping establish that terrestrial gamma-ray flashes originate from thunderclouds (Dwyer, J. R., and D. M. Smith, A Comparison between Monte Carlo simulations of runaway breakdown and terrestrial gamma-ray flash observations, Geophys. Res. Lett., 32, 2005); first identifying and modeling terrestrial electron beams (Dwyer, J. R., et al., High-energy electron beams launched into space by thunderstorms, Geophys. Res. Lett., 35, 2008); and producing the first x-ray images of lightning (Dwyer, J. R., et al., High-speed X-ray Images of Triggered Lightning Dart Leaders, J. Geophys. Res., 116, 2011).
