Professor Elschot's research involves space weather detection and modeling for improved spacecraft designs, and advanced signal processing and electromagnetic wave interactions with plasma for ground-to-satellite communication systems. These topics fall under the Space Situational Awareness (SSA) umbrella that include environmental remote sensing using satellite systems and ground-based radar. Her current efforts are the MEDUSSA (Meteoroid, Energetics, and Debris Understanding for Space Situational Awareness) program, TALIS (Tomographic Array for Lightning and Ionospheric Studies) using ground-based and space-based RF sensors, and using ground-based radar data to characterize the meteoroid population and its threat to spacecraft. She was a member of two NRC panels, in 2010 examining options for detecting and countering near-Earth objects,[2] and in 2011 assessing NASA's meteoroid and orbital debris programs.[3]
In 2011, Professor Elschot co-hosted season three of National Geographic Channel's Known Universe documentary series along with David E. Kaplan, Andy Howell, Michael J. Massimino, and Steve Jacobs.[12] She was interviewed on the Nova ScienceNow Can We Make It to Mars? episode in 2011[13] and the Nova Chasing Pluto special in 2015.[14]
