Jiachen-Liu is a diligent researcher with extensive multi-/inter-disciplinary expertise in biostatistics and bioinformatics, big data, genetics, transcriptomics, epigenomics, proteomics, complex traits and diseases (especially osteoarthritis, sarcopenia, and obesity), metabolomics and metagenomics.

Liu’s work is published in 22 peer-reviewed publications including journals such as Redox Biology, Molecular Cancer, Ageing Research Reviews, Journal of Translational Medicine, Human Genetics and Therapeutic Advances in Neurological Disorder. As of April 2024, these publications have been cited more than 883 times and his H-index is 14 since the first article published in 2020. Liu currently serves on the editorship/ed-itorial boards of journals(e.g.,iMeta), who also worked as a reviewer in several SCI journals such as Age and Ageing, Obesity Reviews, International Journal of Surgery, Diabetes, Obesity and Metabolism, and Molecular Neurobiology.

Liu’s primary research interests include all those areas that are related to addressing the question: What and how gene expression network and environmental factors incur higher risk of, or better protection against, complex diseases, such as sarcopenia and osteoarthritis.

Liu is also interested in generating, analyzing and integrating big data of various omics in vivo in humans. The purpose is to elucidate the impact of gene expression/regulation and protein expression/modification on the disease course in the form of functional networks/modules/pathways and how the knowledge gained on these molecular mechanisms in humans would translate into better prediction/intervention/precision medicine and drug development.
