Dr Wang is a computational biologist. He was trained as a computer scientist initially in China. Impressed by the beauty of Life Sciences and importance of cancer research, he decided to dedicate to the interdisciplinary field of computational biology. Dr Wang pursued his PhD at the University of Cambridge Department of Oncology and Cancer Research UK Cambridge Institute, where his research was concerned with how to infer intracellular signalling pathways from phenotyping screens. In collaboration with experimental oncologists, he also identified three molecularly distinct colon cancer subtypes using an unsupervised classification approach. From 2013 to 2015, Dr Wang did his postdoc training at Harvard Medical School Department of Biomedical Informatics, where he learned advanced techniques in next-generation sequencing data analysis. Dr Wang joined Department of Biomedical Sciences at City University of Hong Kong in Mar 2015, and was promoted to associated professor with tenure in July 2019.

Research Interest

Dr Wang’s major research interest is to better understand the biology underlying cancer using quantitative approaches, with a focus on the following fields:

Cancer Bioinformatics: We have been developing novel methodologies using bioinformatics, systems biology, machine learning and artificial intelligence for integrative analysis of (multi-)omics data (e.g., Sem Cancer Biol 2019, Oncogenesis 2019, Medicine in Omics 2021). Focusing on major malignancies, we are especially interested in multi-omic molecular subtyping followed by comprehensive molecular, histopathological, immunological and clinical characterizations as well as clinical implementations (e.g., Nat Med 2013, Nat Med 2015, Oncogene 2016, Oncogene 2019).

Cancer Biology: We are specialized in leveraging the power of data mining from large-scale, high-throughput public data sets to discovery key regulatory mechanisms followed by in silico and in-house experimental validations (e.g., npj Precis Oncol 2019, BIBM 2021). In collaboration with molecular biologists and experimental oncologists, we have been working on elucidating the genetic and epigenetic regulatory mechanisms underlying cancer development and metastasis (e.g., Genes & Dev 2015, Hepatology 2019, Nat Comm 2021).

Biomarker Development: We have been developing integrated workflows for genome-wide identification of tissue, cell-free and exosome biomarkers for precision medicine (e.g., The Royal Society of Chemistry 2020, Sem Cancer Biol 2021). Together with clinicians, we have been dedicating to multi-centre preclinical and clinical studies about biomarkers for cancer early detection, prognosis, therapeutic response and disease monitoring (e.g., Clin Cancer Res 2018, Gastroenterology 2019, Ann Surg 2019, Sci Adv 2020).
