Dr. Winslow’s work bridges the fields of heliophysics and planetary science, by focusing on observational studies of coronal mass ejections (CME), interplanetary shocks, and galactic cosmic rays to better understand their evolution in the inner heliosphere and their interaction with planetary magnetospheres in the solar system. Her most recent works have focused on investigating the cause of CME complexity changes during propagation in the inner heliosphere, including using observations from the Parker Solar Probe spacecraft. She is the Deputy Lead for the IMAP-Lo instrument, which is partly being designed and built at UNH for NASA’s IMAP mission (to be launched in 2025). In the past, she was a member of the science team for the CRaTER instrument onboard the Lunar Reconnaissance Orbiter and the MESSENGER science team while the spacecraft was orbiting Mercury. Having received research grants since 2015 from NASA and NSF as Principal Investigator (including NASA’s Heliophysics Early Career Award) has allowed her to develop and significantly expand her research program, and thereby to support postdoctoral scholars and graduate students. Please contact her for possible opportunities for students and postdocs.
