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. Her 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.

Mach is the 2020 recipient of the Piers Sellers Prize for world leading contribution to solution-focused climate research. She previously was a senior research scientist at Stanford University and director of the Stanford Environment Assessment Facility. From 2010 until 2015, she 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 co-editor in chief for Climate Risk Management, an editorial board member for Oxford Open Climate Change, and an advisory committee member for the Aspen Global Change Institute, the Stratospheric Controlled Perturbation Experiment, and Carbon180. Across all of her research projects, she 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.
