EAG Early Career Science Ambassador Pim Kaskes travels to GSA Connects 2024

Presenting our recent geochemical and petrographic work on complex rocks from within and outside the Chicxulub impact crater and their comparisons with explosive volcanic deposits.

I am sincerely grateful to the European Association of Geochemistry (EAG) for granting me Early Career Science Ambassador support  to attend the Geological Society of America (GSA) Annual Meeting 2024 in Anaheim, USA. This conference took place between 22 and 25 September 2024, and was an extraordinary experience for me, filled with enriching academic and professional opportunities.

I had the honor of convening a session titled “T122. The Cretaceous-Paleogene (K-Pg) Boundary Interval: From Large-scale Geological Events to Mass Extinction Mechanisms”. This session, which I convened together with Dr. James Witts (Natural History Museum London, UK) and Dr. Isabel Fendley (Penn State University, USA) brought together a diverse group of scientists, including stratigraphers, geochronologists, paleontologists, geochemists, volcanologists, and modelers, to share their latest research findings. The discussions focused on the Chicxulub impact event, the Deccan Traps volcanism, and their role in the profound environmental and biological changes that occurred ~66 million years ago. These topics all aligned perfectly with my postdoctoral project at the Université libre de Bruxelles. The interdisciplinary approach of the session fostered dynamic discussions, enhancing our understanding of one of Earth’s most significant mass extinction events.

Our session at GSA Connects 2024 brought together experts from many different fields (e.g. impact geology, geochemistry, paleontology, sedimentology, paleoclimate modelling) united by their interest in the enigmatic Cretaceous-Paleogene (K-Pg) boundary.
Having a great time with co-conveners Isabel Fendley and James Witts during our lively and well-received K-Pg boundary session.

Beside sharing my research in two oral presentations, the GSA meeting also provided exceptional networking opportunities. I had the privilege to meet and engage with leading experts such as Prof. Brian Huber and Prof. Sean Gulick and early-career researchers in K-Pg boundary research and related fields such as Dr. Vicente Gilabert and Dr. Tushar Mittal. These interactions have opened avenues for potential collaborations and postdoctoral research opportunities. The lively exchanges during the sessions, poster presentations, and informal gatherings were invaluable in broadening my professional network and refining my research goals. I would like to express my deepest gratitude to EAG for supporting my participation in this prestigious event by covering a large part of my travel and accommodation costs. This funding made it possible for me to share my work, gain exposure to groundbreaking research, and advance my academic career right after my PhD. This experience will undoubtedly have a lasting impact on my professional development, and I am eager to apply the insights and connections gained to future projects.

Pim Kaskes

Dr. Pim Kaskes is a postdoctoral researcher and lecturer in geology and geochemistry at the AMGC Research Group of the Vrije Universiteit Brussel (VUB). He earned his PhD in 2023 through a joint program between VUB and Université Libre de Bruxelles (ULB), focusing on the Chicxulub impact event and its role in the Cretaceous-Paleogene (K-Pg) mass extinction. His dissertation, titled “Reconstructing the first moments after the Cretaceous-Paleogene boundary impact event: High-resolution petrography and geochemistry of proximal and distal Chicxulub ejecta,” utilized advanced techniques such as micro-XRF, EMPA and LA-ICP-MS to analyze impact materials from various sites, including the IODP-ICDP Expedition 364 drill core collected within the renowned dinosaur-killing crater in Mexico. Beyond his work on impact events, Dr. Kaskes collaborates on various dinosaur-related geochemistry projects with institutions such as Naturalis in Leiden, the Royal Belgian Institute of Natural Sciences in Brussels, and the Natural History Museum in London.
