Hsieh, Ke-Chiang

Ke-Chiang Hsieh is a Chinese-born astrophysicist. Hsieh earned a doctorate at the University of Chicago in 1969 and taught at the University of Arizona.[1] In 2000, he was elected a fellow of the American Physical Society // My research interest has been in the detection of energetic particles, especially in space. My current interest is in observing space plasma dynamics through the detection of energetic neutral atoms (ENA). Unaffected by magnetic field ENA can travel large distances between their being neutralized and their being detected, thus enabling us to construct spatial distributions (images) of energetic ion populations far away, such as those in the inner and outer heliosphere and those in planetary magnetospheres or ionospheres.
