Katharine Mach is an Associate Professor at the University of Miami Rosenstiel School of Marine and Atmospheric Science and a faculty scholar at the UM Abess Center, focused on environmental science and policy. Mach previously was a Senior Research Scientist at Stanford University and Director of the Stanford Environment Assessment Facility.
Mach's research assesses climate change risks and response options to address increased flooding, extreme heat, wildfire, and other hazards. Through innovative approaches to integrating evidence, she informs effective and equitable adaptations to the risks. From 2010 until 2015, Mach co-directed the scientific activities of Working Group II of the Intergovernmental Panel on Climate Change. This work on impacts, adaptation, and vulnerability culminated in the IPCC’s Fifth Assessment Report and its Special Report on Managing the Risks of Extreme Events and Disasters to Advance Climate Change Adaptation. The associated global scientific collaborations have supported diverse climate policies and actions, including the Paris Agreement.
Mach is a lead author for the IPCC Sixth Assessment Report and the US Fourth National Climate Assessment. She serves as an associate deputy editor for Climatic Change and an advisory board member for the Aspen Global Change Institute and Carbon180. Across all of her research projects, Mach engages in relevant policy processes, and she frequently discusses climate change risk and adaptation with the media, the private sector, nongovernmental organizations, and communities. Mach received her PhD from Stanford University and AB summa cum laude from Harvard College.
