Dr. Haihong Che

Assistant Professor, CSPAR

Biography

Dr. Che received her Ph.D in physics from University of Maryland, College Park, in 2009. Then she worked as a postdoc in University of Colorado, Boulder for two years. In 2011 she moved to Goddard Flight Center in Maryland. In 2014 she became a research scientist in UMD. She joined UAH in 2019 as an assistant professor in space science.

She received the NASA postdoc fellowship in 2011. She received the Inaugural Rene Pellat Memorial Festival Prize, CEA, France in 2017 for her contribution to the fundamental understanding of nonlinear kinetic turbulence in space plasma. In 2019 she received the Inaugural Heliophysics Career award for her original research in magnetic reconnection and nonlinear kinetic instabilities and the applications in helio- and solar physics.

Her research interest is broad, including 1) particle acceleration and transport ; 2) nonlinear Plasma Instabilities, plasma heating, and coherent emission and their applications in space and solar plasma and solar radio bursts; 3) the origin and acceleration of solar wind and solar wind turbulence and the connection to coronal heating; and 4) the onset of fast magnetic reconnection and its application in explosive events in space and astrophysics, such as magnetospheric substorm, solar flares and Gamma-ray bursts.
