He has more than 34 years working and research experience and substantial knowledge and skills in environmental health and infectious diseases. He completed his PhD study at the School of Public Health, Queensland University of Technology (QUT) in 2005. He has been awarded over 7 highly prestigious and competitive grants (including a NHMRC postdoctoral research fellowship, three NHMRC project grants, a QUT Vice-Chancellor Senior Research Fellowship, a Hong Kong Health and Medical Research Funds and ARC Future Fellowship). He has been at the leading edge of research into identifying the major socio-ecological determinants of infectious diseases using spatiotemporal statistical models. He has a leadership role in the NHMRC dengue early warning project between China (China Centre for Disease Control and Prevention (CDC)) and Australia. He has pioneered the development of an early warning of infectious diseases, with real-world application in national and local disease control programs. He has supervised 15 PhD students, 2 Masters research students to completion.
