Professor Joseph Wu leads the infectious disease modeling research in the HKU School of Public Health. His primary research is in influenza epidemiology and control with a focus on pandemic preparedness and response. He earned his PhD in Operations Research from MIT in 2003 and BS in Chemical Engineering from MIT in 1999. His work primarily entails developing mathematical models to assess the potential benefits and resource requirement of mitigation and surveillance strategies for communicable diseases including influenza, hand-foot-and-mouth disease, HPV infection and yellow fever. Since 2013, he has been working closely with the China CDC on the risk assessment and management of avian influenza A/H7N9 epidemics and health economic evaluation of vaccination against hand-foot-and-mouth disease in China.

He is the producer of HKU's first Massive Open Online Courseware (MOOC) Epidemics which has had more than 16,000 people enrolled since its first launch on the edX platform in 2014. He is the director of the Croucher Summer Course Vaccinology for Public Health and Clinical Practice.

He is an affiliated faculty member of the Center for Communicable Diseases Dynamics (CCDD) at the Harvard School of Public Health. He is an associate editor of the American Journal of Epidemiology and a Fellow of the UK’s Faculty of Public Health. He is a member of the Technical Working Group for the WHO Public Health Research Agenda for Influenza. He is a member of the Scientific Committee for the Center for Health Protection in Hong Kong. He was a recipient of Outstanding Young Researcher Award from HKU in 2015.
