Winners of the IAG Young Scientist Award 2021
Our Young Scientist Award was launched in 2006 as our Early Career Researcher Award. It is made annually for research by a young scientist that closely reflects the goals of our Association. The award aims to promote the careers of young scientists who have either developed innovative analytical methods or provided new strategies to improve data quality as applied to the chemical analysis of geological or environmental materials.
We are proud to announce that the winners of the 2021 IAG Young Scientist Award are Alicja Wudarska (Warsaw, Poland) and Tao Luo (Wuhan, China). They will be presenting their research at the 2021 Goldschmidt conference in Lyon, France 4-9 July. During the conference they will also be receiving their IAG awards.
Alicja Wudarska is a postdoctoral researcher at the Institute of Geological Sciences of the Polish Academy of Sciences in Warsaw. The main focus of her research has been the development of new reference materials for isotope analysis of apatite using secondary ion mass spectrometry (SIMS). She has recently completed two projects related to chlorine and oxygen isotopes that she conducted in collaboration with the SIMS laboratory at the GFZ Potsdam. The results of her work were published recently in Geostandards and Geoanalytical Research, and the metrological splits of the apatite samples described therein can be obtained through IAGeo Limited (iageo.com). Currently, Alicja and her team from the SIMS lab are working towards development of reference material(s) for U-Pb dating of apatite, and her project is being supported by an IAG Geoanalytical Research and Networking Grant.
Alicja undertook the study of new apatite reference materials in order to collect the SIMS data for her PhD project. This was focused on the investigation of geochemical processes which shaped the early Archean Isua supracrustal belt (SW Greenland), by means of hydrogen and chlorine isotope measurements in minerals of the apatite group2. In the future, she is planning to apply stable isotope analysis to bioapatite research. She is especially interested in the application of these methods to wildlife conservation.When Alicja is not working, she enjoys exploring the world with her husband as well as gardening, crafts and reading about Australian wildlife.
Tao Luo is an associate professor at China University of Geosciences, Wuhan after receiving his PhD degree. The focus of his research has been the investigation of elemental and isotopic fractionation during LA-ICP-MS analysis and development of novel non-matrix-matched methods for U-Th-Pb dating of accessory minerals.
Tao started to work in geoanalytical research during his master’s degree and was responsible for running their LA-ICP-MS lab as a student-assistant at that time. He investigated ICP-induced fractionation behaviours in LA-ICP-MS and evaluated the influence of argon and helium carrier gases on signal intensities and elemental fractionation in analysis by both ns- and fs-LA-ICP-MS. In addition, Tao has developed a novel, water vapor-assisted method3 for non-matrix-matched determination of U-Th-Pb ages in accessory minerals. This method greatly broadens the wide applications of in situ U-Th-Pb geochronology to diverse accessory minerals without the strict requirement of matrix-matched reference materials4. He applied this water vapor-assisted method for the development of in situ LA-ICP-MS wolframite U-Pb dating for the first time, which solves a very challenging question of the timing and duration of hydrothermal W mineralisation.
Currently, he is working on the development of new reference materials for microbeam analysis of U-Pb geochronology and Hf-O isotopes. When not working in the lab, Tao enjoys hiking and cycling.

Jie Lin is a post-doctoral scientist at the China University of Geosciences (Wuhan), where she majored in isotope analysis. The main focus of her research has been the development of new strategies and methods for Li isotope ratio measurements. Firstly, she provided a method to reduce the memory effect of Li during analysis. Her methodology has been applied in many international laboratories and publicised by Thermo Fisher Scientific. Secondly, she investigated the factors affecting the in situ determination of Li isotopes and developed a procedure for Li isotopic analysis by laser ablation multi-collector mass spectrometry (LA-MC-ICP-MS). Thirdly, she has worked on measuring Li isotopic ratios in carbonate samples and provided accurate and precise δ7Li values for various carbonate reference materials. She has also evaluated the feasibility of Li isotopic analysis in tourmalines by LA-MC-ICP-MS using matrix-matched and non-matrix-matched calibration. Currently, she is researching methods for determining Mg and O isotope ratios by LA-MC-ICP-MS.
When Jie is not working in the laboratory, she enjoys playing badminton, cycling and walking on the East Lake Greenway in Wuhan with her baby.
Michael Weber is a post-doctoral researcher at the Johannes Gutenberg University, Mainz, Germany, in the working group of Applied and Analytical Palaeontology. He is currently investigating the fractionation of stable Sr and Ca isotopes along trophic levels in vertebrates using MC-ICP-MS techniques.
Michael first came in contact with isotope geochemistry during his work as a student assistant, where he applied 230Th/U dating to speleothem samples and performed the chemical separation as well as the mass spectrometric analyses. During his PhD, he started to work intensively on the application of Sr isotope ratios to different kind of geological materials and reference materials, especially in situ analysis using LA-MC-ICP-MS. This finally led to a publication on the development of NanoSr, a new synthetic carbonate reference material, especially designed for carbonate samples with low Sr contents. As well as the geoanalytical work, he is also involved in the reconstruction of past climate variability using speleothem, by applying a wide range of techniques and isotope systems, such as 230Th/U dating, stable carbon and oxygen isotopes, in addition to Sr isotopes. He is currently working with a Neptune Plus at the Institute of Geosciences, performing Sr and Ca isotope determinations of different kinds of biological hard and soft tissues.
When Michael is not working in the lab, he enjoys cycling, playing football and spending time with his wife and their pets.
Winner of 2019 IAG Young Scientist Award
When Martijn received his award he was a senior research associate in isotope cosmochemistry at the University of Bristol where he studied planetary differentiation using a range of mass-dependent isotope systems. Martijn is currently working in the School of Earth and Ocean Sciences at Cardiff University, UK.
Martijn got hooked on isotope geochemistry during his geology degree at the Vrije Universiteit Amsterdam. He was responsible for running the TIMS lab as a student-assistant and quickly took on developing mass spectrometry routines and calibrating spikes for isotope dilution measurements. Development of analytical techniques remained prominent during his PhD at the same institute as he moved onto the realm of double spiking with Pb. Taking advantage of the availability of then prototype 1013 Ω resistors, he developed a technique for the high-precision measurement of ng-size Pb samples.
Martijn joined the Bristol Isotope Group in 2016 after finishing his PhD. He has developed and deployed novel methods in measuring mass-dependent isotope systems to study the differentiation of the Earth. With an optimised Ni double spike method, he has showed that Earth’s mantle is noticeably fractionated relative to chondritic meteorites, potentially reflecting a core formation signature. He has further embraced the possibilities of critical mixture double spiking for studying both Si and Mg isotopic variability at high precision and employed the capabilities of Proteus, a prototype collision cell multi-collector mass-spectrometer, to examine the Ca isotopic systematics of the Moon. When not indulging in this rich isotopic smorgasbord, Martijn enjoys hiking and playing korfball.
Winner of 2018 IAG Young Scientist Award
Alicia is the Edward Sturgis Grew Assistant Professor of Petrology and Mineralogy at the University of Maine. One of the primary focuses of her research is the geochemical connection between the metamorphism that occurs in subducted oceanic crust and the geochemistry of arc volcanoes, i.e. understanding the geochemical fingerprint of subduction. She is particularly interested in single element thermometry and quantifying the spatial and temporal scales of equilibrium in metamorphic rocks.
Alicia has developed a new technique for analyzing Ti in quartz by laser ablation ICP-MS, and has published papers using a wide variety of analytical techniques. Her recent work includes combining LA-ICP-MS analyses of trace elements with SIMS analyses of sulphur and oxygen isotopes in silicates and sulfides. In doing so, she hopes to constrain the composition and evolution of fluids produced during devolatilisation of subducting slabs. She is the head of the new MicroAnalytical Geochemistry and Isotope Centre (MAGIC Lab) at the University of Maine, which houses an Agilent 8900 triple quadrupole mass spectrometer and NWR193 laser ablation system.
When she is not in the lab, Alicia enjoys nordic skiing, cycling, and going out in the field to collect rocks with her colleagues, students and baby girl.
She was recently been co-opted onto the Council of the IAG, with particular responsibility for liaison with the Elements journal.

Peter has been a PhD student at the Department of Geology and Economic Geology, Montanuniversität, Leoben, Austria since 2014.
The subject of his thesis is the potential exploitation of high-technology elements in sphalerite from Eastern Alpine Pb-Zn ore deposits. His research has involved the analysis of sphalerite (ZnS) using LA-ICP-MS, which necessitated the development of suitable reference materials for calibration of the LA-ICP-MS system. Peter devised a sintering technique to produce homogenous ZnS materials doped with a wide range of trace elements, which was published in Geostandards and Geoanalytical Research in 20161.
In addition, he developed a cost-efficient method for sulphur isotope measurements by LA-ICP-MS, using N2O as the reaction gas in an ICP-MS/MS system (paper in preparation). The reference materials he developed, MUL-ZnS1 and MUL-ZnS2, have been distributed to many other laboratories, as the demand for such materials in research related to ore geology continues to grow. When he is not in the lab, Peter enjoys cave diving and renovating a 300 year old mill.
