Prof Geoff Stevens is a Laureate Professor in the Department of Chemical and Biomolecular Engineering at The University of Melbourne.

Prof Stevens leads an internationally recognised separations group, is a Project Leader in the CRC for greenhouse gas remediation (CO2CRC). He was Secretary General of the International Solvent Extraction Committee (1996-2016) and is on the editorial boards for 'Solvent Extraction and Ion Exchange' (1999-2016), 'Hydrometallurgy' (1994-2016), 'Chinese journal of Chemical Engineering' and the 'Chem Eng Journal'.

Research interests are in the areas of separation processes, particularly solvent extraction, interfacial phenomena and emulsion stability. The research is primarily in the hydrometallurgical field but also covers aspects of food, pharmaceutical processing and environmental or waste water processing.

Prof Stevens has been named in Engineers Australias list of the 100 Most Influential Engineers 3 years in a row. Sponsored by Engineers Australia, the list aims to acknowledge engineers who have a positive influence on society.

Professor Stevens has been bestowed with the honour of Melbourne Laureate Professor in September 2011 in recognition of an outstanding career and contribution to the discipline and the University.

Professor Stevens researching separation processes with particular focus on solvent extraction received the Patricia Grimshaw Award for Mentor Excellence in 2014. This award recognizes his outstanding contribution as a mentor providing exceptional support and respect for colleague development. He was also nominated for the Australian Awards for University Teaching in the Category: High Impact Intervention for progression retention and attainment.
