Dr Eric Lau is an infectious epidemiologist at the University of Hong Kong with a focus on surveillance and transmission dynamics of infectious diseases in human and animals, and assessment of infection control measures. He utilized quantitative analytical methods to characterize transmission dynamics in the community setting and at the human-animal interface. His previous work has contributed to the understanding and control of emerging human and zoonotic diseases such as scarlet fever, SARS, MERS, avian influenza A(H7N9) and COVID-19. He has published over 120 peer-reviewed journal articles and serves on the editorial board of BMC Infectious Diseases and PLOS Neglected Tropical Diseases, and as a statistical reviewer at The Lancet Child & Adolescent Health.

Marc Ka-chun CHONG is currently an Assistant Professor in Jockey Club School of Public Health and Primary Care and an Assistant Professor (by courtesy) in Department of Obstetrics and Gynaecology in CUHK. Since 2006, Marc has been working as a biostatistician in the Centre for Clinical Research and Biostatistics (former Centre for Clinical Trials), possessing rich experience in conducting various statistical analysis of academic and industrial clinical trials. He is also a statistical consultant for different consultation projects, for example, Development of Refined Population-based Model to Inform Resource Allocation, Surgical Outcomes Monitoring and Improvement Programme, and Intensive Care Units Outcomes Monitoring Program held by Hospital Authority.
Learning objectives:
- To understand the principle, assumptions, procedure, and limitations of commonly used biostatistics methods in emergency medicine research, such as C-statistics, multivariable logistic regression and survival analysis.
- To learn more advanced statistical methods such as propensity score matching, bootstrapping, K-means clustering
Format:
This workshop is designed for participants with experience in EM research. Each topic will start with a real-life example EM researchers likely encounter in their work, followed by solutions provided by academic biostatisticians. The theoretical basis and practical steps of each biostatistics method will be explained. There will be a 5-minute Q&A session at the end of each topic.
