Society Awards 2025 Winners

Congratulations to the very well deserved recipients of our 2025 Society Awards and Funds, which recognise their significant achievements and contribution to the geoscience community. The formal presentation of awards will be celebrated on President's Day, 11 June 2025, at Burlington House in London

Wollaston Medal

The Society's most esteemed medal, the Wollaston Medal, first awarded in 1831 to William Smith, celebrates geoscientists whose research has had significant influence "by means of a substantial body of excellent research in either or both 'pure' and 'applied' aspects of the science" advancing our understanding of the Earth.

This year, it is awarded to Professor Barbara Sherwood Lollar, University Professor in Earth Sciences, University of Toronto. Renowned for her research of ancient waters and deep subsurface biosphere, Professor Lollar is a most worthy recipient, with over 200 published peer-reviewed papers.

Professor Lollar pioneered the development of Compound Specific Isotope Analysis (CSIA), identifying a new natural isotope tracer of unparalleled sensitivity to investigate the clean-up of hydrocarbon contaminants in the environment, and quantify the microbial and chemical transformation of groundwater contaminants, which has had a considerable impact on the field of drinking water remediation globally.

Her work has contributed to the evaluation of deep geologic repositories' potential for disposal of low- and high-level nuclear waste and carbon capture and storage, as well as identifying new areas of hydrogen-rich rock with potential to contribute clean energy alternatives. Moreover, her discoveries around habitability of groundwaters in the Earth's deep subsurface are driving insights into mission planning for Mars, Enceladus and Europa.

Barbara Sherwood Lollar has received numerous accolades, including the Eni Award in Protection of the Environment (2012), Companion of the Order of Canada – an honour bestowed on only 180 living Canadians – and the C.C. Patterson Award (2019) for environmental chemistry. Notwithstanding, to receive the Wollaston Medal carries great significance for her:

"The Geological Society of London was the crucible in which so many of the founding principles of geological sciences arose – principles that laid the foundation for how scientists observe, investigate and understand the planet. It is an immense thrill to receive the Wollaston Medal and an honour to contribute to a community that has persevered throughout history in pursuit of an understanding of the Earth driven by facts, by hypothesis testing, and by the rigorous application of reasoning, thereby establishing a strong foundation for public policy and action."

Also highly prestigious are the Lyell, Murchison, and William Smith Medals, which honour recipients for their exceptional research contributions.

Lyell Medal

Professor Hugh Jenkyns, Emeritus Professor at Oxford University

Professor Hugh Jenkyns

Professor Hugh Jenkyns, Emeritus Professor at Oxford University, receives the 2025 Lyell Medal, for his pioneering research in 'soft' rock studies.

Professor Jenkyns, sedimentary geologist, stratigrapher and paleoceanographer, is held in the highest regard for his work defining and exploring 'oceanic anoxic events' (OAEs) to explain the occurrence of globally widespread, coevally deposited Mesozoic black shales.

Professor Jenkyns' models of OAEs have found widespread application, including within industry due to their implications for source rock genesis. 

He has been in the vanguard of developments in Mesozoic palaeoceanography and the study of OAEs and in the application of new and developing geochemical tools demonstrated by over 35,000 citations. He has trained and influenced many scientists worldwide through his work and international collaborations, as well as inspiring decades-worth of students through his teaching.

Murchison Medal

Professor Jenny Collier, Imperial College London

The 2025 Murchison Medal, for significant contribution to 'hard' rock studies, is awarded to Professor Jenny Collier, an expert in Marine Geophysics at Imperial College London. She has made groundbreaking contributions to the study of the structure of the oceanic lithosphere and the Quaternary evolution of continental shelves.

Professor Collier led the pioneering multibeam bathymetry survey of the UK continental shelf, a project that revealed the existence of catastrophic megafloods that once separated Britain from Europe. Recent work on the subduction of slow-spread oceanic lithosphere has shown its importance for the global solid-Earth water cycle.

Professor Collier has also made significant advances in understanding volcanic rifted margins, focusing her work primarily on seismic and magnetic methods in the South Atlantic and Northwest Indian Ocean. Her findings have challenged traditional models, revealing the complex geological history of these regions, where inherited structures play a crucial role in shaping their evolution.

William Smith Medal

Professor David Selby, Durham University

Professor David Selby

Professor David Selby is this year's recipient of the William Smith Medal for contributions to applied and economic geology. David Selby, Durham University, has earned global recognition in the field of rhenium-osmium (Re-Os) geochronology and isotope geochemistry, establishing himself as a leader in this area.

Professor Selby's research focuses on the systematic development and application of the Re-Os isotope system to metallic and hydrocarbon economic geology, fostering an extensive network of international collaborators and playing a key role in the geological community.

With a diverse research portfolio, including over 200 publications, David contributes to economic geology, supporting ore deposit studies and mineral exploration strategy. In addition, he has employed his methodology to investigate fundamental geological processes, from volcanism to mountain weathering, to ice sheet dynamics, as well as expanding his research beyond geology into the field of archaeology and atmospheric pollution.
