Ph.D, Atmospheric and Space Sciences, The University of Michigan, 1993
RESEARCH INTERESTS:
Dr. Fok's main research interests are studies of the radiation belt and the ring current during geomagnetic active periods, understanding the mechanisms responsible for their intensification and decay by numerical modeling and data analysis. She has developed a comprehensive kinetic model that can compute and predict the energetic plasma fluxes in the inner magnetosphere. Dr. Fok is a participating scientist of the IMAGE mission and is heavily involved in neutral atom imaging. The modeling tools she has developed contribute greatly in interpreting images from the 3 neutral atom imagers (LENA, MENA and HENA) on IMAGE.
