Dr. St. Cyr has maintained an active research presence in solar activity, space weather forecasting techniques, interplanetary dust, sungrazing comets, quantifying the economic impacts of space weather on the power grid, and various policy topics associated with heliophysics.
Dr. St. Cyr is a recipient of the 2019 Robert H. Goddard Award of Merit. He is a U.S. Army veteran; and he received a B.S. in Astrophysics from the University of Oklahoma, and a Ph.D. in Astronomy from the University of Florida in 1985. He retired from NASA-Goddard in March 2020 as Senior Project Scientist for Heliophysics missions in development. Most recently, he was the U.S. Project Scientist for the ESA/NASA Solar Orbiter Collaboration, successfully launched on February 10, 2020. From 2002-2008, he was Senior Project Scientist for NASA’s Living With a Star Program (LWS) where he was a fundamental contributor to shaping that program with NASA HQ and the heliophysics community. He also served as Acting Project Scientist for Solar Dynamics Observatory (SDO) during its development. Between 1998-2002, he was Deputy Project Scientist for NASA’s STEREO mission.
He is internationally recognized as an early proponent of, and an expert in, the applied research area known as “space weather”. He has extensive experience in the remote sensing of coronal mass ejections (CMEs) based on his experience analyzing data from the SMM, SOHO, and STEREO spacebased coronagraphs, as well as the groundbased Mauna Loa coronagraphs. He has significant experience designing ground segments for spaceflight missions, and developing and operating scientific instruments on spacebased platforms and for solar eclipse expeditions.
