Helen Czerski: The Physicist Who Makes the Ocean Talk
Who Is Helen Czerski?
Helen Czerski is a British physicist, oceanographer, writer, and broadcaster who has become one of the UK’s most recognisable voices in science communication. Born in Manchester on 1 November 1978, she is now Professor of Environment and Society at University College London (UCL), where she investigates the extraordinary physical processes that take place where the ocean meets the air. Her career unites rigorous research with an exceptional gift for explaining complex ideas clearly and enthusiastically to the public.
Early Life and Education
Helen Czerski studied Natural Sciences (Physics) at the University of Cambridge, graduating with first-class honours from Churchill College. She remained there to complete her PhD in experimental physics in 2006, exploring the ignition of energetic materials. After earning her doctorate, she moved into ocean science, combining physics, acoustics, and environmental observation to understand the dynamics of bubbles and waves.
Her post-doctoral years took her to the Scripps Institution of Oceanography in California and to the Graduate School of Oceanography at the University of Rhode Island. Later, she joined the University of Southampton, focusing on how bubbles produced by breaking waves influence air–sea gas exchange—the fundamental process that links the ocean and atmosphere.
Helen Czerski at University College London
Now based in London, Professor Helen Czerski leads research at UCL in experimental ocean physics, using high-speed photography and advanced acoustic techniques to capture the behaviour of bubbles in the upper ocean. Her work analyses how these tiny pockets of air shape global climate by mediating the exchange of gases such as carbon dioxide between sea and sky. Through field expeditions and laboratory experiments, she studies wave–bubble processes, light scattering, and the acoustics of breaking waves—all crucial for climate and marine-atmosphere modelling.
In October 2025, she became Professor of Environment and Society, reflecting her commitment to connecting environmental science with public understanding. For more than eleven years at UCL she has been a leading figure bridging physics, engineering, and environmental studies.
Research and Scientific Contribution
Helen Czerski’s research explores how small-scale physical processes in the ocean contribute to large-scale climate systems. Her fascination with bubbles began when she realised how these tiny features could alter the sound, chemistry, and optics of seawater. By analysing the behaviour of bubbles, she helps explain how the ocean absorbs gases, transmits sound, and reflects light—phenomena that are vital for weather prediction and carbon-cycle modelling.
Her experiments often employ high-speed imaging and acoustical sensors to study micro-scale turbulence. The results support a deeper understanding of air–sea gas transfer, oceanic soundscapes, and marine ecology. Few scientists have communicated the beauty and complexity of such physics as vividly as Helen Czerski.

Writing Career and Books
Storm in a Teacup
Her debut book, Storm in a Teacup: The Physics of Everyday Life, transforms ordinary experiences—boiling water, stirring milk, or lighting candles—into lessons in physics. It won both the Italian Asimov Prize and the Louis J. Battan Author Prize from the American Meteorological Society, praised for making physics warm, accessible, and humorous.
Blue Machine
Her second book, Blue Machine: How the Ocean Shapes Our World, published in 2023, is an ambitious exploration of the ocean as Earth’s greatest engine. It became a BBC Radio 4 Book of the Week and in 2024 received the Wainwright Prize for Conservation Writing. The book highlights the ocean as a dynamic system driving weather, climate, and the chemistry of life—an example of Helen Czerski’s ability to blend storytelling with deep scientific understanding.
