Chengbo Liu is a Research Professor and PhD Supervisor, OPTICA Fellow, and recipient of the National Excellent Young Scientists Fund. He serves as Deputy Director of the Institute of Medical Engineering. He is an Editorial Board Member of Photoacoustics (JCR Q1), Deputy Editor-in-Chief of Biophotonics Discovery, Deputy Secretary-General of the Biomedical Photonics Committee of the Chinese Optical Society, Assistant Director of the National Key Laboratory of Medical Imaging Science and Technology Systems, and Director of the Shenzhen Key Laboratory of Molecular Imaging. He received his B.S. in Biomedical Engineering (2007) and Ph.D. in Biophysics (2012) from Xi’an Jiaotong University, and was a visiting PhD student at Duke University from 2009 to 2011. His research focuses on photoacoustic imaging technologies and instrumentation, with active translation toward industrial and clinical applications. He proposed the theory of zero-background targeted photoacoustic imaging and developed cross-scale photoacoustic imaging systems spanning micro-, meso-, and macroscales, enabling in vivo human peripheral vascular imaging. He has led over 20 major research projects, including NSFC Key Projects, the Excellent Young Scientists Fund, Major Research Programs, key projects of the National Key R&D Program of China, international and strategic collaborations, and CAS instrumentation programs. He has published over 130 SCI-indexed papers, including more than 90 as first or corresponding author in journals such as Science Advances, Nature Communications, and PNAS, with over 6,000 citations (Web of Science) and an H-index of 50. He holds more than 20 granted invention patents, has authored News & Views for Nature Biomedical Engineering, and serves as a reviewer for Nature Methods, Nature Biomedical Engineering, Nature Communications, Science Advances, and related journals.
