I have collected rocks and fossils since I was a kid, but I became interested in fossil plants in particular while an undergraduate at the University of Pennsylvania, working with Hermann Pfefferkorn on Carboniferous floras from the Canadian Arctic. I continued to pursue paleobotany in my graduate work with Kevin Boyce at the University of Chicago, where I studied the evolution of reproductive morphology in fossil and living conifers. I then spent several years as a postdoc at Yale, working with Peter Crane in the School of Forestry and Michael Donoghue in the Department of Ecology and Evolutionary Biology. Before joining the faculty at Stanford, I was a professor in the Ecology and Evolutionary Biology Department at Brown University.
