Hi there! I'm a research scientist in the Physics Department of the University of Wisconsin-Madison. My research focuses on the structure and dynamics of the interstellar medium of galaxies. Right now, this is a rather perfunctory web page. Over time, I hope to expand it greatly! Anyway, let me know if you have any questions!

• Useful map of Milky Way showing spiral arms, velocity field and a curve showing where tau=2 for H-alpha emission --- Postscript version
• FORTRAN code to calculate a nifty approximation for radiative cooling
• FORTRAN code to calculate emissivities of helium recombination lines
• Analogous code to calculate emissivities of hydrogen recombination lines (Storey & Hummer 1995, MNRAS, 272, 41)
• A paper on the distribution of free electrons in the Galaxy
• 3D MHD Simulations of Supernova Remnants in the ISM
• A very strange unexplained linear feature in the ISM (looks like a jet contrail!) Paper-- --Image-- --Press release
• Conference proceeding on rotation in Galaxies (2000) RevMexAC 9, 256
• A Survey of Interstellar Structures (dormant)
• Tests of various data servers..
