Tyler Grover

Title/Position
Graduate Teaching Assistant
Tyler Grover has research interests in mathematical physics: string theory, gravitation, and quantum field theories. He currently works with Dr. Vincent G. J. Rodgers exploring features of Thomas-Whitehead Projective Gravity. Current projects include search for space-time solutions and predicted corrections for particle physics.
Jasper Halekas

Jasper S. Halekas, Ph.D.

Title/Position
Professor
Jasper Halekas’s research seeks to broaden our understanding of the impact of the Sun and the solar wind on our solar system and its evolution. To accomplish this, he designs and builds instruments to measure charged particles around moons and planets and in the interplanetary medium. Jasper's research spans planetary science and space physics, with a unifying theme the use of charged particle measurements to remotely infer plasma processes. He is the instrument lead or instrument scientist for particle sensors on the MAVEN, Parker Solar Probe, and TRACERS spacecraft, and the deputy PI for the THEMIS-ARTEMIS and Lunar Vertex missions.

DHartley

David Hartley, Ph.D.

Title/Position
Assistant Research Scientist/Engineer
Dave uses in-situ spacecraft observations to study the dynamics of the Earth’s magnetosphere. He uses plasma wave observations from the EMFISIS instrument on NASA’s Van Allen Probes satellite mission, as well as MMS measurements, to study very low frequency (VLF) waves which play a critical role in driving variations in the different particle populations contained within the inner magnetosphere. Dave is currently Principal Investigator of two NASA grants, and Co-Investigator on an NSF-GEM grant.
