Malcolm Wallace serves as Associate Professor and Reader in the School of Geography, Earth and Atmospheric Sciences, Faculty of Science, at the University of Melbourne. He obtained his PhD in Geology from the University of Tasmania and joined the University of Melbourne in 1991 as a Lecturer in the School of Earth Sciences, advancing to his current role. Wallace coordinates the Geology major and leads the Basin Analysis & Modelling team. His academic career emphasizes sedimentary geology and stratigraphy, with key interests in carbonate sedimentology and diagenesis, ancient reef systems, basin analysis, neotectonics, Precambrian geology, carbonates, and coal geology. Research highlights include Neoproterozoic Snowball Earth glaciations, where analysis of iron-rich rocks from South Australia, Namibia, and California demonstrates oxygen-rich seawater oases near glacial margins that supported early complex life amid global ice cover. Additional foci encompass the Cryogenian-Ediacaran transition, Cenozoic shelf evolution in southeast Australia, Gippsland and Murray Basins, carbonate-hosted ore deposits, meteorite impacts, active tectonics, and petroleum geology, benefiting minerals and petroleum industries through insights into lead-zinc deposits and seismic exploration.

Wallace's influential publications include "Origin of the in situ stress field in south-eastern Australia" (Basin Research, 2004), "Subglacial meltwater supported aerobic marine habitats during Snowball Earth" (Proceedings of the National Academy of Sciences, 2019), and studies on Neoproterozoic marine carbonates, with contributions to Nature and Geology. His scholarship has amassed over 6,600 citations on Google Scholar. Honors comprise the Selwyn Medal (Geological Society of Australia Victoria Division, 2008), Stillwell Medal (2005, best paper in Journal of Earth Sciences), and Faculty of Science Dean's Award for Excellence in Graduate Research Supervision (2023). He has guided 13 PhD students to completion, 65 honours students, and supervises ongoing PhD research on Neoproterozoic extreme climates and related sedimentary processes.
