I am a postdoctoral researcher at Stanford University, where I study ecological and environmental change over the last 10,000 years, with an emphasis on anthropogenic changes over the last ~500 years. My research synthesizes modern, historic, and paleoecologic records to study how diversity and abundance have changed through time–on local and regional scales–in response to past environmental changes. My field work includes excavation of packrat middens, small mammal mark-recapture surveys, and collection of lake cores to reconstruct past biodiversity and environment.
Learn more about my work on the Anthropocene at the Jasper Ridge Biological Preserve website (project description and blog). Visit research and publications pages to learn more about past and on-going projects; visit teaching and outreach pages to see how I am relating science to students and general audiences.
