Dr Greg Martin is a Senior Lecturer in the Department of Chemical and Biomolecular Engineering at The University of Melbourne. His research in the field of bioprocess engineering aims to develop fundamental understanding for application in large-scale biotechnological processes. This has included research into the bioconversion of lignocellulose to ethanol, application of bacteriophage to wastewater treatment, and investigations into the physicochemical aspects of dairy processing. He currently leads the Algal Processing Group, a research group that is developing efficient downstream processing technologies for the conversion of microalgal biomass into different bioproducts. Dr Martin's research interests include:

Microalgal processing
- Efficient large-scale cell disruption of microalgae using high pressure homogenisation
- Application of advanced lipidomic methods to microalgal biotechnology
- Development of efficient lipid extraction processes for concentrated microalgal pastes

Dairy processing
- Physicochemical behaviour of milk during membrane filtration and the manufacture and rehydration of dairy powders
- Dynamics and structure of casein micelles
- Functionalised milk streams and double emulsions

Biofuel production processes
- Recovery of triacylglycerides from microalgae for biodiesel production
- Dilute acid hydrolysis and enzymatic conversion of lignocellulose to fermentable sugars
- Recombinant bacteria for fermentation of lignocellulose-derived sugars to ethanol
