Curriculum Vitae

Most of the material in the universe is invisible. That is one of the most dramatic, perplexing, and yet persistent findings of modern astrophysics. We know that dark matter exists because of the way it tugs on galaxies, heats cosmic gas, and bends the light from distant objects. My research involves mapping the large dark halos within cluster of galaxies, looking for structures that reveal the nature and composition of dark matter.

I was chair of the scientific organizing committee for the latest SnowCluster international galaxy cluster physics meeting.

I am co-director of the SFSTAR astrophysical computing facility. I have authored the Joint Analysis of Cluster Observations (JACO) package for modeling galaxy clusters; and the Hrothgar MCMC model fitting toolkit, which has been used to tackle a diverse array of problems across physics and astronomy.
