Ching Jianhong

Assistant Professor


Contact: 66013678

Jianhong Ching, is an Assistant Professor at the Cardiovascular and Metabolic Disorders (CVMD) Programmed of Duke-NUS Medical School. He is a specialist in metabolomics studies using mass spectrometers and applying his techniques in metabolism research. 

Jianhong graduated with a PhD in Life Sciences at NUS and joined CVMD as a postdoctoral fellow in 2011. During his career at Duke-NUS, he helped to set up Singapore’s first fee-for-service Metabolomics Core, which eventually became one of Singapore’s most prominent metabolomics research and service lab which researchers engage with. Jianhong was eventually promoted to Assistant Professor and heads the Metabolomics Core.

2023- present: Public Sector Engagement Manager, Association of Official Analytical Chemists (AOAC) Southeast Asia Section

Jianhong has extensive experience in analytical chemistry and has applied metabolomics techniques to various metabolic disease related projects. His research interest is to develop new techniques to trace biochemical pathways for understanding of the kinetics of important disease biomarkers. This technique uses stable isotopes of carbon, nitrogen or hydrogen, which can be incorporated into the endogenous analytes of biological systems. These labelled analytes will be metabolised by the biological system, forming various labelled downstream intermediates that are monitored by a mass spectrometer. This method, known as fluxomics, provides kinetic information and traces specific biochemical pathways, an advantage over metabolomics which shows only static observations. 

Jianhong is also interested in applying metabolomics to other fields, such as the gut microbiome, and novel foods. He is advising the Asian Microbiome Library (AMILI) as well as the Singapore Food Agency on the use of metabolomics in areas of microbiome research and food safety respectively.
