Complete Publication List

Experimental space plasma physics, atmospheric and magnetospheric electrodynamics, middle atmosphere electrodynamics, thunderstorm and lightning electrodynamics.

My research involves the experimental investigation of electrical parameters in the Earth's environment, in particular, the study of the electromagnetic energy flow that couples separated environments such as the atmosphere, the ionosphere, and the magnetosphere. Active projects include: CAREII dusty-plasma rocket experiment Electric field measurements in F-region ionosphere to be launched from Norway in 2013 (NRL support);   C/NOFS Optical Lightning Detector in the VEFI electric field experiment launched Apr 2008 into equatorial orbit to study ionospheric irregularities (NASA and USAF sponsored), and real time global lightning studies using VLF techniques with the WWLL (World Wide Lightning Location network) (see wwlln.net for more information) and experiments to use lightning as a powerful radar to probe the D-region.  Additionally, proposals in the works for new balloon flights. 

Students are encouraged to be vitally involved in hardware projects and data analysis in all of these research areas. All instruments are built in our lab by the students or the professional engineering staff. Most projects include the opportunity for student travel.
