One main aim is to study the evolution of large scale structure and the physics of the intergalactic medium at an epoch when the first stars and galaxies are forming and the baryons in the universe are largely in the form of hydrogen and helium gas. My main collaborators are Michael Rauch (OCIW), George Becker (Kavli Institute, Cambridge), and Bryan Penprase (Pomona College). Most of our work involves observations of Quasar Absorption Lines using the spectrographs on the two 10 meter Keck Telescopes in Hawaii and the 6.5 meter Magellan Telescopes at the Las Campanas Observatory in Chile.
