I have retired, but I still supervise students for research projects. My former graduate students are: Neil Raha, David Earn, Ben Weiner, Victor Debattista, Vince Jacobs, Juntai Shen, Ricardo Zánmar Sánchez, Michael Solway, and Carl Mitchell.
My main interests are structure and evolution of galaxies, their formation and their dark matter content.
I use N-body simulations to compute the evolution of isolated galaxies. I have made my simulation code public through the website GALAXY, with a detailed on-line manual at this url
I am also the author, with Kristine Spekkens, of the public software package DiskFit that can be used to fit disk galaxy models to either photometric images or kinematic data. DiskFit can be downloaded from this url.
