Academic biography

Dr. Se¨¢n Jordan is Associate Professor in Biogeochemistry and Astrobiology in the School of Chemical Sciences at Dublin City University. He is a leading researcher in the fields of geobiology, astrobiology, and the origins of life. As the Principal Investigator of the ProtoSigns Lab at DCU, he spearheads pioneering investigations into fundamental questions surrounding the emergence and evolution of life on Earth. He is currently a member of the DCU Life Sciences Institute (LSI) and the Origin of Life Early-career Network (OoLEN). 

Se¨¢n obtained his BSc (Hons) in Environmental Science from DCU in 2009. Following this he gained practical experience as a research assistant in the National Centre for Sensor Research. In 2012, after a short time in Australia, he returned to DCU to complete his PhD in Biogeochemistry which was awarded in 2016. That same year he accepted a position as Postdoctoral Research Associate at University College London, investigating the first cell membranes at the origin of life. In 2021 he secured a ¡®la Caixa¡¯ Foundation Postdoctoral Junior Leader Fellowship (Marie Sk?odowska-Curie COFUND) to pursue his work on protocells, organic biomorphs, and biosignature detection at Instituto Superior T¨¦cnico in Lisbon, Portugal. He then joined DCU as an academic in 2023. 

Se¨¢n¡¯s research is driven by a multidisciplinary strategy that integrates novel experimental approaches, state-of-the-art analytical techniques, and computational modelling to elucidate the complex processes that shaped early life and early Earth environments. His work delves into key aspects of prebiotic chemistry, exploring the formation of protobiomolecules and protocellular structures under plausible primordial conditions. A recipient of prestigious funding awards, including the SFI Pathway award and the European Research Council Starting Grant, Se¨¢n leads a dynamic research group focused on understanding life's origins, evolution, and existence. Through innovative experimental techniques and field expeditions to geologically significant sites, the ProtoSigns Lab is focused on pushing the boundaries of prebiotic chemistry at the origin of life, investigating how the resulting structures may be preserved in the rock record, and the potential effects this may have on our interpretation of biosignatures from the early Earth and elsewhere in our Solar System.
