Session Co-Chairs

Emily Willis, Space Environments Analyst, NASA

Emily graduated from the University of Alabama in Huntsville with a PhD in electrical engineering. She currently Analyzes space environment data and space weather conditions for impacts to NASA missions.

She also develops design environments for space plasma and radiation and performs spacecraft charging analysis using Nascap-2k, SPIS, and NUMIT2.0.

Gregory Wilson, EMA Senior Scientist

Gregory Wilson specializes in space environment interactions with materials and spacecraft as well as electromagnetic effects of lightning and other high voltage phenomena. He has worked on numerous projects contracted by NASA, SpaceX, AFRL, and other space focused organizations.

Gregory has published dozens of articles focusing on electron ranges in materials, secondary electron yield, surface voltage measurements, and other space-based material characterization topics. He has recently worked on high fidelity electromagnetic simulations to understand the coupled interactions of surface and internal spacecraft charging. He is currently participating in the design and construction of EMA’s SERE facility as well as the development of EMA3D® Charge.

Jacob Johnson, EMA Scientist

Jacob Johnson is a Scientist at Electro Magnetic Applications, Inc. (EMA) where he is involved in developing in depth trainings for the EMA3D® Charge modeling software. Jacob graduated from Georgia Institute of Technology in 2021 earning a Bachelor of Science in Physics with a minor in Nuclear and Radiological Engineering.

During his time at GT, he engaged in undergraduate research at the nuclear fusion lab on campus. He worked with researchers from across the world on studying particle transport with Tokamak fusion reactor phenomena, as well as analyzing and validating large data sets.
