F.G. Houtermans Award | European Association of Geochemistry

About the F.G. Houtermans Award

The F.G. Houtermans award is bestowed annually to a scientist within 12 years from the start of PhD, which must be completed. Eligibility is determined by the status of the candidate at the close of the year in which nominations are received and not the year the award is presented; hence, for the 2021 F.G. Houtermans Award, candidates should have started their PhD in 2008 at the earliest.

The award recognizes a single exceptional contribution to geochemistry, published as a single paper or a series of papers on a single topic. It is named in honor of Friedrich Georg Houtermans, a Dutch-Austrian-German physicist.

The award is presented annually at the Goldschmidt Conference. The award consists of an engraved medal, an honorarium (1000 Euros) and a certificate.

Paolo Sossi, ETH Zürich, Switzerland

2021 Houtermans Award medallist

Paolo Sossi is a Swiss National Science Foundation Ambizione Fellow, based at the ETH Zürich since 2019 in the group of Prof. Max Schmidt. He holds both Italian and Australian citizenship, with his formative years spent in Adelaide, Australia, under the scientific tutelage of Prof. John Foden and Prof. Galen Halverson on the application of non-traditional stable isotopes to igneous systems. He obtained his Ph.D. in 2015 from the Australian National University under the supervision of Prof. Hugh O’Neill, combining high temperature experiments to calibrate isotopic fractionations observed in nature. From 2015 to 2018 he held an ERC post-doctoral position at the Institut de Physique du Globe de Paris, where he was engaged with Prof. Frédéric Moynier on the cosmochemical applications of isotopic and elemental variations among meteorites.

Paolo’s research interests broadly lie in how the high temperature physico-chemical properties (structure, oxidation, geochemistry) of melts, minerals and vapours shape the composition and architecture of the terrestrial planets. To do so, he employs laboratory experiments to mirror geochemical processes, whose products are analysed by a combination of spectroscopic and mass spectrometric techniques in order to derive thermodynamic quantities and physical formalisms.

His early work focused on characterising the direction and magnitude of iron isotopic fractionation in igneous systems through analysis of mafic and ultramafic rocks and experimental analogues. He subsequently became interested in other isotopic systems (V, Cr and Zn) and exploited their differing geochemical properties to understand irradiative processes in the early solar system, conditions of the Moon-forming impact, and the delivery of moderately volatile elements to Earth. More recently, Paolo has been involved in determining the solution properties and vapour species of moderately- and highly volatile elements, the redox evolution of Earth’s mantle and the mechanisms for the production and loss of atmospheres around rocky bodies.

Kun Wang, Washington University in St. Louis, USA

2020 Houtermans Award medallist

Kun Wang is an assistant professor of Earth and Planetary Sciences at Washington University in St. Louis. Kun grew up in Tangshan, China and received a B.Sc. degree in geology at the China University of Geosciences, where he worked with Rong Liu on the Ningqiang carbonaceous chondrite and with Weibiao Hsu on Grove Mountain Antarctic meteorites. Kun then moved to the USA and received a Ph.D. from Washington University in St. Louis in 2013, where he studied iron isotope cosmochemistry with Frédéric Moynier. After receiving an Origins of Life Initiative Prize Postdoctoral Fellowship, Kun moved to Harvard University and collaborated with Stein Jacobsen to develop a new method for potassium isotope analysis. In 2016, Kun returned to St. Louis joining the faculty of Washington University. In recent years, his research has been focused on various applications of K stable isotopes such as studying continental weathering and hydrothermal alteration; tracing subducted crustal materials and mantle heterogeneity; and understanding the initial physical and chemical conditions surrounding the formation and differentiation of the terrestrial planets.

Stefan Lalonde, CNRS / Institut Universitaire Européen de la Mer, France

2019 Houtermans Award medallist

Stefan Lalonde is a CNRS researcher at the Laboratoire Géosciences Océan, Institut Universitaire Européen de la Mer and Université de Bretagne Occidentale, in Brest, France. A Canadian raised in Nova Scotia and Montana, Stefan completed BSc studies at McGill University and obtained an MSc degree in Geomicrobiology (2006) and PhD degree in Geochemistry (2011) at the University of Alberta. Stefan’s research is focused on the evolution of the Precambrian surface environment and biosphere.

Stefan’s work has combined laboratory experiments and sedimentary geochemical data to understand the chemical composition of seawater in the Archean and Paleoproterozoic, with a particular focus on iron-rich chemical sedimentary rocks such as banded iron formations (BIF). During PhD work in Edmonton with Kurt Konhauser, and continuing during postdoctoral work in Brest with Olivier Rouxel, Stefan constructed large BIF geochemical datasets that helped constrain the evolution of marine nutrients and redox status in deep geological time, including the histories of phosphorus, nickel, chromium, uranium, cobalt, copper, and zinc.

Stefan joined the CNRS as a researcher at the Laboratoire Géosciences Océan in Brest in 2013. His focus turned to incipient oxidative weathering on the Archean to Paleoproterozoic Earth, including kinetics of mineral oxidation and microbial oxygen production. He elaborated novel models for early oxidative weathering by benthic microbial mat communities. He guided studies of fossilized microbial mats in the Barberton Greenstone Belt (S. Africa) that revealed colonization of the land surface ca. 3.2 billion years ago and indicated differences in carbon and nitrogen cycling between terrestrial and marine settings at that time. Stefan has also published on trace element uptake onto iron oxides and bacterial surfaces in natural and laboratory settings, on microbial silicification, and on paleoenvironmental applications of iron, molybdenum, and germanium stable isotopes.

Work in progress, funded by the European Commission and in close collaboration with Philip Fralick (Lakehead University), is aimed at understanding links between carbonate production, seawater composition, and photosynthesis in Archean shallow waters via field and drill core study of some of Earth’s oldest (Mesoarchean) carbonate platforms preserved in Northern Ontario, Canada.

Morgan Schaller, Rensselaer Polytechnic Institute, USA

2018 Houtermans Award medallist

Morgan Schaller is currently an assistant professor at Rensselaer Polytechnic Institute, in Troy, NY. After receiving dual Bachelors degrees in both Geology and Biology in 2005, he moved to Rutgers for an MS in hydrogeology and a PhD in Geochemistry (2012). Schaller’s interests are broadly in the history of the Earth system and changes in climate over long timescales. Morgan uses light stable isotopes to trace the interaction and transfer of elements through the atmosphere, biosphere, and solid earth, specifically linking geologic processes to the carbon cycle. He has investigated the atmospheric effect of ancient, continental-scale volcanic eruptions (Large Igneous Provinces), and subsequent changes in the concentration of greenhouse gases due to chemical weathering. The results of Morgan’s dissertation were published (with Dennis Kent, James Wright, and Paul Olsen) in a series of three papers where he reported (for the first time) clear empirical evidence for: 1) short-term Triassic pCO2 increase resulting from Central Atlantic Magmatic Province volcanism (Science 2011); 2) subsequent long-term pCO2 drawdown through chemical weathering (EPSL 2012); and 3) long-term pCO2 decrease resulting from drift of Pangea into Earth’s humid tropical belt (GSA Bulletin 2015). In 2014, he joined the faculty at RPI and in the following year built their Stable Isotope Lab.

Morgan’s current focus is largely on the changes in the concentration of major and trace atmospheric gases over long timescales with the goal of better understanding what ultimately controls the transfer of gases between the solid earth and the atmosphere. His most recent work is in developing a new analytical method for determining the concentration of gases in the ancient atmosphere using fluid inclusions in soil carbonates, and the discovery of impact ejecta at the Paleocene-Eocene boundary (published in Science, 2016), changing our interpretation of that climatic event. With engaging colleagues and an enthusiastic group of graduate students at RPI, he aims to reconstruct the record of, and chip away at, the causes for the evolution of atmospheric oxygen concentrations through Earth’s history, and evaluate the specific climatic effects of large extraterrestrial impacts.

Julie Prytulak, Imperial College London, UK

2017 Houtermans Award medallist

Julie Prytulak is a Lecturer in the Earth Science and Engineering Department at Imperial College London. Julie is Canadian, with many formative years spent in the wide expanse of the Saskatchewan prairies before she received a B.Sc honors degree in Geology from Carleton University, Ottawa in 2002. She then moved across the continent and into the USA to complete an M.S. degree at Washington State University in 2004, working with Jeff Vervoort on the Hf-Nd isotope composition of subducting sediments. A relocation to the United Kingdom followed, and she received a PhD in 2008 from Bristol University, where she used short-lived uranium-series isotopes, (231Pa in particular), to determine the melt productivity beneath ocean islands with Tim Elliott. She then held a postdoctoral position at Oxford University, followed by a NERC fellowship at Oxford and Imperial College London. During her time at Oxford (2008-2011) she developed, alongside Sune Nielsen and Alex Halliday, the first protocol to precisely and accurately measure natural stable vanadium isotope variations. In 2013 she joined the faculty at Imperial College London as co-leader (with M. Rehkamper, D. Weiss and T. van de Flierdt) of the Mass Spectrometry and Geochemistry (MAGIC) isotope group.

Julie’s research can be broadly described as igneous geochemistry, and she employs an array of techniques including major and trace elements, radiogenic isotopes and most recently stable isotopes. Her primary research investigates the drivers of mantle melting and the subsequent evolution of such melts, most notably in intraplate and island arc settings. Her recent work focuses on the causes of stable isotope variations in vanadium and thallium during magmatic processes. In collaboration with many valued petrological, geochemical and geophysical colleagues, she aims to determine whether stable isotope variations in magmas are related to intensive source parameters such as oxygen fugacity, are dominated by crystal chemical controls and thus reflect mantle lithology, or are resultant from the input of isotopically exotic components.

Kate Hendry, University of Bristol, UK

2016 Houtermans Award medallist

Kate Hendry is a Royal Society University Research Fellow in the School of Earth Sciences at the University of Bristol. She received her MSci in Natural Sciences from Queens’ College, University of Cambridge, in 2004, before carrying out her DPhil in Antarctic Biogeochemistry at Oxford University with Ros Rickaby. After eighteen months of postdoctoral research in Oxford, she was awarded a Doherty postdoctoral scholarship in 2009 to work in the Department of Marine Chemistry and Geochemistry at Woods Hole Oceanographic Institution (with Laura Robinson, Olivier Rouxel and Tim Eglinton). In 2010, she published her first paper on silicon isotopes in biogenic opal, and was awarded a National Science Foundation Geology and Geophysics grant to continue this research as a co-investigator at WHOI. Since returning to the UK, initially as a Research Lecturer at Cardiff University before moving to Bristol, she has been awarded research grants from the Leverhulme Trust, the Natural Environment Research Council, the Royal Society and the European Research Council to continue her work on silicon isotopes, as well as trace metals and their isotopes.

Kate has been developing the use of silicon isotopes in deep-sea siliceous sponges in biomineralisation and palaeoceanographic studies since 2008. Her calibration work is based largely on sponge samples she collected on three oceanographic research cruises to Southern Ocean and Equatorial Atlantic. She has also worked with her colleagues on producing some of the first silicon isotope geochemical archives using sponge spicules from deep sea sediment cores to reconstruct past changes in oceanic silicon cycling. Her palaeoclimate work has focused on understanding changes in silicon cycling over the last deglaciation, working with Jerry McManus, Jim Hays, and Mark Brzezinski amongst others. She has worked in deeper geological time with Alex Halliday and colleagues, on coupled Southern Ocean diatom-sponge opal records from the Eocene-Oligocene boundary. Her current work includes understanding the links between biochemistry and isotope geochemistry in silicifiers on the microscopic scale, to the large scale spatial distribution of silicon and silicon isotopes in modern and past oceans.

Caroline Peacock, University of Leeds, UK

2015 Houtermans Award medallist

Caroline Peacock is an Associate Professor in the School of Earth and Environment at the University of Leeds, UK.
Caroline is originally from London, UK and holds a Bachelor of Science Honours and a PhD degree from the University of Bristol, UK. After graduating her PhD in 2005, Caroline did a short post-doc at the University of Bristol before becoming a lecturer in geochemistry in the School of Earth and Ocean Science at the University of Southampton, UK in 2006. In 2009 Caroline moved to the University of Leeds as a lecturer in biogeochemistry, and became an associate professor of biogeochemistry in 2013. Caroline’s research focuses on the biogeochemistry of metals in terrestrial and marine environments, with particular focus on the molecular-level processes that govern the distribution of metals between soils, sediments and natural waters. These processes ultimately control the abundance of metals in both modern and ancient environments, and are therefore key to understanding metal cycling on both a local and global scale. Caroline uses a combination of laboratory experiments, advanced synchrotron-based spectroscopic techniques and geochemical modeling to achieve her research goals.
