I am a graduate student working with David Ackerly at UC Berkeley studying the evolution of plant life history.
The focus of my dissertation is the evolution of plant traits that allow populations to persist in fire prone ecosystems, specifically Mediterranean-type shrublands.
Previous research that I have been involved with includes investigations of leaf hydraulic physiology and ecosystem carbon cycling.
