Dear Geochemists, Early bird registration for GGRiP has now closed, however you still have 10 days left to register and submit your abstracts (https://ggrip2026.co.uk/<https://eur03.safelinks.protection.outlook.com/…)mp;reserved=0>). It is shaping up to be a great meeting! We have a fantastic set of confirmed Keynote speakers (listed below): We are also thrilled to announce that our 2026 Postdoctoral Medal winner is Dr. Lena Chen (University of Bristol), who will give a GGRiP keynote on her winning publication “Mineralogical controls of the oceanic nickel cycle”<https://eur03.safelinks.protection.outlook.com/?url=https%3A%2F%2… in Nature Communications. This year, we had an extremely high-quality set of applications, so we also give honourable mentions to two further outstanding contributions: * Dr Paul Beguelin (Cardiff University) for the paper: “Variations in Hawaiian Plume Flux Controlled by Ancient Mantle Depletion”<https://eur03.safelinks.protection.outlook.com/?url=https%3A%… in AGU Advances. * Dr Kun Zhang (UCL) for the paper: “Ocean deoxygenation after the Sturtian Snowball”<https://eur03.safelinks.protection.outlook.com/?url=https%3A%2… in Nature Communications.

Barbara is a geochemist managing the LA-ICP-MS lab at The Open University. Her background is in high-grade metamorphism and anatexis of crustal rocks. Her work includes the effects of prolonged high-temperature metamorphism on isotopic and element signatures in geochronometers as well as the influence of partial melting reaction on mobilising critical elements into granitic melts. She also champions the Technician Commitment at the OU to increase the visibility, recognitions and career development of research technical professionals. * Prof. Tim Elliott, University of Bristol. Tim has spent his career making various isotope measurements of mantle derived rocks, bits of other planetary bodes and the occasional biogenic carbonate. He learned his trade amidst the concrete cows on Milton Keynes and further indulged this habit in the somewhat more uplifting environments of Lamont Doherty Earth Observatory and the Vrije Universiteit, Amsterdam before retuning to the UK. Over the past 25 years in Bristol, he has been pleasantly surprised by the new vistas offered by multi-collector plasma mass-spectrometry and has dabbled with the capabilities offered by adding a collision cell to such instruments. * Dr Alexandra Auderset, University of Southampton. Alexandra is a paleoclimatologist/paleooceanographer and Anniversary Fellow at the University of Southampton. Her research focuses on marine archives to investigate climate change across glacial/interglacial cycles, during the Neogene era, and warming events that occurred in the Cenozoic period, such as the Middle Miocene and Early Eocene Climate Optima. She uses various emergent proxies, including lipid biomarkers and fossil-bound nitrogen/carbon isotopes to study interactions between marine nutrients, ocean circulation, oxygen minimum zones and global climate. * Dr. Rebekah Moore, Imperial College London (The Geochemistry Group’s Early Career Researcher Prominent Lecture 2025/26). Rebekah is a Research Fellow at Imperial College London, where she has been a researcher and a member of the MAGIC isotope geochemistry group for the last twelve years. Since gaining her MSci in Geoscience in 2013 from Durham University, she has pioneered multidisciplinary research addressing critical health, food systems and environmental challenges, such as zinc deficiency, using ICP-MS, LA-ICP-MS and MC-ICP-MS. This year, she has collaborated with mycologists and social scientists on two exciting projects that aim to improve the intake of micronutrients by vulnerable populations, using ecologically-beneficial farming techniques and food production methods. * Dr. Savannah Worne, Loughborough University (The Geochemistry Group’s Early Career Researcher Prominent Lecture 2025/26). Savannah is a Research Fellow at Loughborough University. Her work spans aquatic environmental biogeoscience, with interests in algal productivity, nutrient cycling, aquatic pollution, and the impacts of climate change on ecosystem structure and function. Her current fellowship focuses on understanding how nutrient cycling and harmful algal blooms interact in managed lakes. By combining water and sediment isotope geochemistry with ecological analyses, her research takes a holistic view of ecosystem health and explores how these systems may respond to climate change and human pressures. * Dr. Lena Chen, University of Bristol (The Geochemistry Group’s Postdoctoral Medal Winner 2026). Lena is a Senior Research Associate at the University of Bristol. Her research lies between geochemistry and environmental mineralogy. Her interest in geochemistry began during her MSci in Geology at Imperial College London, where she used trace metal stable isotopes to investigate the interactions between sediment and seawater. Building on this foundation, her PhD at the University of Leeds examined how mineral transformation processes in sediments impart isotopic signals to trace metals. Her current research focuses on the durability of uranium and thorium-bearing ceramic minerals as potential hosts for immobilising radioactive waste. She investigates the mechanisms and kinetics of their dissolution in groundwater, contributing to the development of a robust safety-case for the long-term disposal of radioactive waste. See you in Bristol! George
