Katharine Mach, a climate scientist, is part of a rural air quality research project, in collaboration with the Sean N. Parker Center for Allergy and Asthma Research at Stanford, that examines wildfires’ effects on respiratory illness. Her research is focused on assessment of climate change risks and response options. From 2010 to 2015, Mach co-directed the scientific activities of Working Group II of the Intergovernmental Panel on Climate Change, which focuses on impacts, adaptation and vulnerability. Mach is the director of the Stanford Environment Assessment Facility (SEAF) at the Stanford Woods Institute for the Environment, a senior research scientist in Stanford’s School of Earth, Energy & Environmental Sciences and a visiting investigator at the Carnegie Institution for Science. Advancing foundations for action, her research is focused on integrative assessment of climate change risks and response options. The goal is innovating and evaluating new approaches to assessment, simultaneously applying them to inform decisions and policy. Priorities include methods for integrating evidence, applying expert judgment, and communicating resulting syntheses of knowledge.
