Biography

I am Professor and Cooperative Extension Specialist in the Environmental Science, Policy and Management department and affiliated Professor of Geography at UC Berkeley. I am an accomplished innovator in geospatial data, analysis and visualization. I am dedicated to bringing cutting-edge mapping technology, training, and research support to students, staff, faculty, and the public. My group uses a range of geospatial data and analytics – from spatial modeling, remote sensing, drones, lidar, historical archives, surveys, participatory mapping, and the field (although not always at the same time!) - to gain insights about how and why California landscapes are changing, and what that change means for those who live on, use, and manage our lands. My work enables interdisciplinary collaboration, data-rich analytics research, and active outreach across a number of scientific domains (forests, agriculture, wetlands, climate change) with significant societal impact.
