Gian Andreone was a Postdoctoral Research Associate at the Princeton Space Physics Department interested in developing ion instruments for future space physics missions and analyzing charged particle data from those and current missions. His thesis work at the University of Iowa focused on developing new electron instruments and analyzing electron data around Mars. His specific research interests included looking at charged particle distributions and what they can tell us about the interaction between neutrals and charged particle populations in Space Plasma environments. While at Princeton he worked on the SWAPI instrument on the IMAP mission and helped to develop electronics and test chambers in the lab run by Professor David McComas. His other research interests included studying the moons which orbit Jupiter. Specifically, how newly ionized particles ejected from Jupiter's moons interact with the Jovian magnetosphere.
