I was educated at the
University of Chicago (AB in Mathematics, 1973) and
Princeton University (PhD in Astrophysical Sciences, 1977). I was a faculty
member at the
University of Colorado from 1980 till
2003, when I moved to Wisconsin.
My research area is theoretical astrophysics, especially plasma astrophysics
. I'm jointly appointed in Astronomy and Physics.
I am affiliated with the Plasma Physics Program here and Director of the
Center for Magnetic
Self Organization, funded through the NSF Physics Frontier Centers program.
Most of my work relates in one way or another to the origin and evolution of
astrophysical magnetic fields--in stars, galaxies, and the intergalactic
medium--and the ways in which magnetic fields affect their environments. My work is supported by NASA and the NSF,
for which I'm most grateful.
I'm currently working with UW students Daniel Lecoanet and Jennifer Stone and Assistant Scientist
John Everett. Postdocs Yansong Wang and Ben Brown are arriving soon.
I am delinquent in maintaining this web page, but you
can trace my research
activity through ADS and astro-ph. You can trace
my physical activity by looking on a map of Madison for a slowly
moving dot - I'm a dedicated runner
