Kris Klein's research focuses on studying fundamental plasma phenomena that governs the dynamics of systems within our heliosphere as well as more distant astrophysical bodies. He has particular interest in identifying heating and energization mechanisms in turbulent plasmas such as the solar wind.

Dr. Klein is serving the Deputy Principal Investigator for the HelioSwarm mission, a planned observatory to launch by the end of this decade nine spacecraft to measure the dynamics and evolution of turbulent plasmas at multiple points across multiple scales. In 2022, he received the Landau-Spitzer Award for Outstanding Contributions to Plasma Physics. He has been with LPL since 2017.
