*Apologize for multiple postings* *Don`t forget: This is the last month to catch the early registration deadline *for the: "Recent Developments and Applications in earth sciences of electron probe micro-analysis". A virtual workshop that will be offered in the period 25-28 March 2024. The workshop is on the use of the electron probe microanalyzer (EPMA) with particular emphasis on modern developments and geological applications. Meet our lecturers (vol.2): *Chris Hayward* is a geologist and EPMA specialist at University of Edinburgh, Scotland. He has run EPMA labs at Cambridge (2002-2007) and Edinburgh (2007-present). These labs have had diverse ranges of clients and samples including most types of minerals in terrestrial and extra-terrestrial samples, tephras, archaeomaterials, ores, and experimental alloys for aerospace applications. Published research interests have included the formation of the Witwatersrand gold deposits of South Africa, developments of new analytical protocols for EPMA of crypto-tephras and Ni-base superalloys, tephrochronology, Icelandic volcanism, and geoarchaeology - especially quarrying and stone-working in ancient Greece, field survey, and palaeo-topographic reconstruction of archaeological sites. *Ery Hughes *studied Natural Sciences (BA), specialising in Earth Sciences (MSci), at the University of Cambridge (UK) and then completed her PhD at the School of Earth Sciences, University of Bristol (UK). Her PhD focussed on developing and combining various microanalytical techniques for the analysis of volcanic rocks. These included novel techniques to quantify H2O, CO2, and Fe oxidation state of melts prior to eruption, with a particular focus on EPMA and SIMS, on samples from Etna (Italy) and Ōkataina (NZ). She was a post-doctoral scholar at the Division of Geological and Planetary Sciences, Caltech (USA) and is now a Volcanic Fluid Geochemist at Te Pū Ao | GNS Science (Aotearoa New Zealand). From 2017–2019, she was the first student representative for the European Microbeam Analysis Society (EMAS). In 2017 she won the EMAS Young Scientist Award; 2018 the MAS Castaing Award; and 2022 the IAG Young Scientist Award. *Pierre Lanari* is Assistant Professor and leader of the group Computational Petrology and Geochemistry at the Institute of Geological Sciences of the University of Bern (Switzerland). He earned his PhD in geosciences from the University of Grenoble (France) in 2012. His work aims to understand the conditions and tempo of metamorphic processes by combining high-resolution geochemical analysis with thermodynamic modelling. Pierre has contributed to the development of important tools for community use including the mapping software XMapTools as well as to the theory, technique and application of iterative petrological models. He recently co-edited a volume of the Reviews in Mineralogy &Geochemistry series on petrochronology and is associate editor of Computers & Geosciences. *Serguei Matveev* is a EPMA specialist. He has Graduated from Moscow State University 1991), Geology/Geochemistry. In 1994 – 1997 received his Ph.D. in experimental petrology (MPI Mainz, RSES Canberra, University of Cologne). Then, became Postdoc in Muenster (1998 – 2000) with the duty for the operation and maintenance of JEOL JXA-8600. In the period 2000 – 2012 hold the Faculty service officer at U of A, Edmonton (Operating/Maintenance JEOL JXA-8900). 2012 – 2015 VU Amsterdam (Operation/Maintenance JEOL JXA-8800). In the period 2015 – 2018 Operating JEOL JXA-8530F, XRF, SEM, dual beam instruments at Utrecht University. Since then (until now), holds a position at JEOL (Germany) GmbH, as Application specialist EPMA, and SEM instruments. *Lucia Spasevski* graduated with a BSc and MSc in Chemistry. She started her career as a Sales and Application specialist for an SEM distributor in Croatia. In 2016 she joined the Semiconductor Spectroscopy and Devices group at Strathclyde University, Glasgow where she obtained a PhD in Physics, using different microscopy techniques such as EPMA and CL. She joined Oxford Instruments in July 2021 as a Product Scientist, developing analytical approaches that solve critical problems in the semiconductor industry. Then in 2023, her role changed to Product Manager, where she will be focusing on the WDS market and managing the AZtec Wave products but will be taking on responsibility for further products within the EDS portfolio. Based on our experience, we are pretty sure that this workshop will provide VALUABLE new knowledge for the undergraduate students, postgraduates, PhD, postdocs, senior scientists, and lab managers. Every participant will have the chance to learn the basics and more advanced aspects of electron probe microanalysis. The early registration fee is 40 euros and includes the attendance at the workshop, and FULL access to online material (recordings, presentations, transcripts). Late Registration (after 31st December 2023) is possible, however, the registration fee is increased by 30% at 52 Euros. Therefore, book your virtual seat as soon as possible.
