Prof. Dr. Timothy A. G. Langrish is a faculty member in the School of Chemical and Biomolecular Engineering at the University of Sydney. He received his B.E. in chemical and process from the University of Canterbury, NZ, in 1985, and his D.Phil. in engineering science from the University of Oxford, UK, in 1989. He is a world leader in drying technology, particularly spray drying and the drying of timber. His work, with Professor Fletcher, on transient flows in spray dryers, has uncovered new types of flow instabilities that are fundamental to improving practical outcomes in reducing the deposition of particles on spray dryer walls. His research interests include drying technology; particle technology; and food engineering, with links to food digestion studies and energy and exergy studies. He integrates adjacent scientific disciplines such as spray drying and extraction (chemistry), together with materials engineering, such as the control of degrees of crystallinity in material components through control of the drying process.
