This lecture was recorded by Helen Czerski on the 19th of February 2026 at Barnard's Inn Hall, London

Helen Czerski is a physicist and oceanographer with a passion for science, sport, books, creativity, hot chocolate and investigating the interesting things in life. 

She is a Professor at the Department of Mechanical Engineering at University College London and her research focus is the physics of breaking waves and bubbles at the ocean surface. These bubbles change underwater sound and light, help transfer gases from ocean to atmosphere (helping the ocean breathe) and also eject ocean material into the air. She has spent months working on research ships in the Antarctic, the Pacific, the North Atlantic and the Arctic, and is an experienced field scientist.
