Dr Thomas Leong is an early career research fellow in the ARC Dairy Innovation Hub based at the University of Melbourne, Australia. He has expertise in the application of ultrasound for the formation of nanoemulsions and double emulsions. Dr Leong’s primary research interests are in the area of ultrasound processing, dairy technology and food engineering, and he has published 23 peer-reviewed journal articles, 4 book chapters and 1 patent on topics in these fields.Professor Sivakumar Manickam (Siva) is a Chemical Engineer specializing Process Engineering of Nanomaterials especially Nanopharmaceuticals at the University of Nottingham, Malaysia campus. His research group focusses on the process development of cavitation based reactors towards technologically important nanomaterials. The group also looks into the development of pharmaceutical nanoemulsions as well as utilizing novel carbon nanomaterials to design biosensors for the early detection of cancer and diabetes. He is also the Associate Dean of Research and Knowledge Exchange, Faculty of Engineering and is the Director of the Centre for Nanotechnology and Advanced Materials. He was the recipient of JSPS fellowship, Japan. He has published ~200 peer reviewed journal and conference papers. He is a Fellow of Royal Society of Chemistry (RSC), Fellow of Higher Education Academy (UK) and member of the Institute of Nanotechnology (IoN). Wu Li is a Ph.D. candidate from the Sonochemistry Research Team located in the School of Chemistry at the University of Melbourne, Australia. During his MSc, he developed an understanding of sonochemistry from his work on the ultrasound-assisted deposition of metals. He recently started his Ph.D. on the topic of ultrasonic emulsification and its application in dairy systems as part of the ARC Dairy Innovation Hub, with a focus on understanding the fundamental aspects of ultrasonic emulsification.Dr Gregory J. O. Martin is aSenior Lecturer in bioprocess engineering at The University of Melbourne’s Department of Chemical Engineering. His research in the field of bioprocess engineering aims to develop a fundamental understanding for application in large-scale biotechnological processes. This has included research into the use of ultrasound for the production of double emulsions, application of bacteriophages to wastewater treatment, and investigations into the physicochemistry underlying various dairy processes.Dr Martin has been a Chief Investigator on a number of Australian Research Council Grants including a Discovery Project, two Linkage Projects and the Industry Transformation Research Hub in Dairy Innovation. Dr Martin is an Associate Editor for the Journal of the American Oil Chemists’ Society and the head of the Algal Processing Group at The University of Melbourne. He has over 40 publications in leading international journals.Professor Muthupandian Ashokkumar (Ashok) isa physical chemist specializing in sonochemistry. He teaches undergraduate and postgraduate chemistry and is a senior academic staff member at the School of Chemistry, University of Melbourne. He is also one of the associate deans (International) in the Faculty of Science. Ashok is a respected sonochemist who has developed a number of novel techniques to characterize acoustic cavitation bubbles and has made major contributions to the field of applied sonochemistry in the Materials, Food and Dairy industry. His research team has developed a novel ultrasonic processing technology for improving the functional properties of dairy ingredients. His recent research involves the ultrasonic synthesis of functional nano and biomaterials that can be used in energy production, environmental remediation and diagnostic and therapeutic medicine. He is the deputy director of an Australian Research Council Funded Industry Transformation Research Hub (ITRH; Industry Partner: Mondelez International) andleading the encapsulation project. He has received $ 15 million research grants to support his research work, which includes several industry projects. He is the editor-in-chief of Ultrasonics Sonochemistry, an international journal devoted to sonochemistry research with a Journal Impact Factor of 4.8). He has edited/co-edited several books and special issues for journals; published more than 340 refereed papers in high impact international journals and books; and delivered over 150 invited/keynote/plenary lectures at international conferences and academic institutions. Ashok has successfully organized 10 national/international scientific conferences/workshops and managed a number of national and international competitive research grants. He has served on various University of Melbourne management committees and scientific advisory boards of external scientific organizations. Ashok is the recipient of several prizes, awards and fellowships, including the Grimwade Prize in Industrial Chemistry. He has been a Fellow of the RACI since 2007.
