Dean of the Columbia Climate School; Professor of Climate

Sustainable energy technologist who leads the Columbia Climate School, bridging thermal transport research, nanomaterials and building energy efficiency with real world deployment. She served as chief scientist in the US Department of Energy's Building Technologies Office, advised Breakthrough Energy Ventures and co-founded Edifice Analytics, a startup delivering virtual energy audits for buildings.

Kevin Ochsner

Kevin Ochsner

Professor of Psychology; Director, Social Cognitive and Affective Neuroscience Lab

Social cognitive neuroscientist who maps how the brain regulates emotion.
