Scientist studying climate implications of hydrogen.
I am a climate scientist on a mission to translate the best available science into effective, practical, and actionable strategies to curb climate change in the coming decades. My current focus is the climate implications of hydrogen energy systems.
I work closely with policy and business experts, economists, lawyers, and other scientists to provide climate action guidance for governments, companies, and investors across the world. I am especially passionate about and committed to communicating complex science to non-experts by combining plain language with storytelling and powerful visuals.
