BIOGRAPHICAL NOTE
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 .
