Professional Biography
Carl Norlen is a Research Scientist with the NASA Earth Exchange (NEX) at the NASA Ames Research Center contributing to the Wildfire, Ecosystem Resilience, & Risk Assessment Initiative (WERK) project in partnership with the state of California. Carl is leading the creation of fuel data sets to aid in understanding the impacts and effectiveness of California’s increased investment in fuel treatments.
Previously, Carl served as a Presidential Management Fellow (PMF) with the USGS National Land Imaging program and USDA Forest Service Pacific Southwest Research station. As a PMF, Carl worked to better understand the needs of end users for Earth Observation based data, acted as a liaison for USGS to the National Space Council, and conducted research on impacts of urban fires on people and communities.
Prior to that Carl earned an MS and PhD from University of California, Irvine studying the impacts of droughts and fires on California forests, worked as a middle school science teacher in Gwinnett County, Georgia, and high school college access professional with the Upward Bound Programs at University of California, Riverside. Carl is passionate about making science actionable through meaningful and sustained partnerships with communities to advance equitable and science-based solutions to environmental problems.
