Mike is a geophysicist involved in charting and understanding the multitude of magnetic fields encountered around the planets and their moons. He was educated at the California Institute of Technology (B.S., M.S. ,1976), Princeton University (Ph.D., 1984) and is employed by NASA as the lab chief for the Planetary Magnetospheres Lab.
