Christina Cohen earned her B.S. in physics from the University of New Hampshire and her M.S. and PhD in physics from the University of Maryland and has been a research scientist at the Space Radiation Laboratory at the California Institute of Technology for over 25 years.  She helps design and calibrate instruments to measure solar energetic particles (SEPs), such as those on the Advance Composition Explorer (ACE), the Solar Terrestrial Relations Observatory (STEREO), Parker Solar Probe (PSP) and the Interstellar Mapping and Acceleration Probe (IMAP) missions.  Using these and other SEP data, Christina studies the variation of characteristics of (SEP) events as a function of time, solar longitude and radial.  These events are one aspect of space weather and understanding their acceleration and transport is key to developing a capability for accurately predicting space weather hazards.  Christina is an AGU Fellow and was the Editor for Space Physics for the AGU publication Eos for nearly 10 years, and served as AGU Space Physics and Aeronomy Section President.  She is currently one of the Deans of NASA’s Heliophysics Summer School.
