- Fellowship in 1999 at Naval Postgraduate School
Under the support from Croucher Foundation, Dr Cheung worked as a postdoctoral fellow in the Meteorology Department of Naval Postgraduate School at Monterey, California for two years and then promoted to research assistant professor. In 2004 he joined the National Science and Technology Center for Disaster Reduction of Taiwan as an associate research fellow where he extended his experience to natural hazard research as well as operational mitigation. He joined the Macquarie University as a teaching faculty in 2008.
Teaching and research comprise most of Dr Cheung's current work. On teaching he serves as convenor and instructor to various courses in the Climate Science program in Macquarie University. He is also working with several Honours Degree and PhD students as their principal supervisor.
On research, his current interests are in several broad areas that include tropical meteorology especially tropical cylone dynamics and their long-term variability; monsoon systems and their relationships with global climate variability; dynamical system and complexity approaches to weather and climate modeling. He is also much involved in research on natural hazards in the form of extreme events, impacts on them under climate change and associated risk analysis.
