Professor of Physics and AstronomyLois L. Rodgers ProfessorDepartment Chair
Jim LaBelle is an experimental space plasma physicist. He has been at Dartmouth since 1989. He earned his undergraduate degree in physics from Stanford University (1980), followed by masters and doctorate degrees in applied physics from Cornell University (1982 and 1985). He did post-doctoral work at the Max-Planck Institute for Extraterrestrial Physics in Garching, Germany (1985-7) and at Utah State University in Logan, Utah (1987-9). He is a member of the American Geophysical Union and the International Union of Radio Scientists. He has had visiting fellowships at the Max-Planck Institute for Extraterrestrial Physics (1997, 2000-2001) and at the University of Sydney (2008). In 2010, he was appointed to the inaugural Lois L. Rodgers Professorship at Dartmouth.

Works in progress
Cusp Alfven and Plasma Electrodynamics Rocket (CAPER), rocket experiment including DC-5MHz wave experiments, particle experiments, Langmuir probes, magnetometers, and wave-particle correlators. To be launched from Andoya, Norway in November, 2015.
Ground-level radio receivers at: South Pole Station, Antarctica; Sondrestrom, Greenland; Churchill, Manitoba; Toolik Lake, Alaska; and in Automatic Geophysical Observatories P1, P2, P3, P4, and P5, Antarctica. Measuring polarization and arrival bearings of auroral radio emissions including auroral hiss, medium frequency burst, 2fce/3fce/4fce/5fce roar, ground-level Auroral Kilometric Radiation, other natural emissions, lightning-generated atmospherics, and man-made broadcast signals.
Ground-level antenna/preamps deployed at Dartmouth College, Siena College, MIT/Haystack Observatory, and to be deployed at 1-2 additional sites, combined with digital software defined radio receivers, in some cases using the Intercepted Signals for Ionospheric Science (ISIS) array, to measure gravity waves and TIDs via Doppler sounding using commercial radio signals.
Statistical studies of waves and particles in the polar cusp environment using data from the Fast Auroral Snapshot (FAST) satellite.
