RISA People

Dr. Dong is a Research Assistant Professor at the Department of Food Science and Nutrition, The Hong Kong Polytechnic University (PolyU). He received his BSc degree in Applied Chemistry in Taiyuan University of Technology in 2006, MSc and PhD degrees in Analytical Chemistry from the Central South University in 2009 and 2013 respectively. Before his appointment as a Research Assistant Professor, he served as a Research Associate and Postdoctoral Fellow in PolyU and the University of Hong Kong.

Dr. Dong's research mainly focuses on the analysis of large-scale metabolomics and proteomics data derived from liquid-chromatography hyphenated by tandem mass spectrometry using machine learning algorithms and statistical methods, develop easy-to-use tool and algorithms to accurately and confidently answer the biological questions at hand. These includes (i) the identifications of metabolites, proteins and protein post-translational modifications; (ii) the quantifications of these biological molecules and (iii) the interpretations of the analytical results for answering biological questions, e.g., discovery of biomarkers related to a disease, using the machine learning algorithms and statistical methods. Currently, Dr. Dong’s research aims to understand the physiological mechanisms in ageing and ageing related diseases, investigate the health benefits of Traditional Chinese Medicines (TCMs) with the utilization using multi-omics (metabolomics and proteomics) techniques, promote their proper use through providing scientific evidence for the medical community and general public.
