Siobhan A. (Sasha) Wilson is a Senior Lecturer and ARC DECRA Fellow in biogeochemistry within the School of Earth, Atmosphere and Environment at Monash University in Melbourne, Australia. She obtained her B.Sc. (Hons) in physics from McMaster University in 2003 and her M.Sc. and Ph.D. in environmental geochemistry from The University of British Columbia in 2006 and 2010, respectively. Sasha held a NASA Postdoctoral Fellowship at the Indiana University node of the Astrobiology Institute from 2010 to 2011. She has been a faculty member at Monash University since 2011. She received the 2016 E.S. Hills Medal from the Geological Society of Australia and the 2017 Mineralogical Association of Canada Young Scientist Medal for her contributions to geochemistry.
Sasha and her research group are focused on delivering applied solutions for tailoring element cycles for carbon, metal and metalloid sequestration within minerals in geoengineered landscapes, mining environments and mineral processing circuits. On the fundamental side, her group is developing the use of alteration minerals in meteorites and fossils for (palaeo)environmental reconstruction, working to understand the role of gas–mineral reactions in sedimentary systems, and investigating the relative roles of microbial metabolism and organic geochemistry in organomineralisation.
