BIOGRAPHY:
Prof. Ed X. Wu is Chair Professor of Biomedical Engineering and holds Lam Woo Professorship in Biomedical Engineering. He joined the University of Hong Kong Department of Electrical and Electronic Engineering in 2003. Before joining HKU, Prof. Wu was an Associate Professor of Radiology and Biomedical Engineering at Columbia University in New York where he led the NMR Microimaging Laboratory. From 1990 to 1998, Prof. Wu was the lead technical member in development of the world first 3D positron emission tomography (PET) system and an ultrahigh field magnetic resonance imaging (MRI) system at Columbia University. At present, Prof. Wu is the founding Director of the interdisciplinary Laboratory of Biomedical Imaging and Signal Processing, and Research Director of 3T MRI Unit at HKU. He served as the Program Director of Medical Engineering Program from 2009 to 2013 and Associate Dean (Research) of HKU Faculty of Engineering from 2013 to 2016. His current research encompasses (1) MRI physics, data acquisition and image reconstruction algorithms through intelligent computing, and MRI system engineering for accessible healthcare; and (2) study of large-scale brain circuits and functions through high-field functional MRI, NMR diffusion and spectroscopy, optogenetic modulation, electrophysiology, behavioural assessment, and modelling.
Prof. Wu presently is the Asia-Pacific Editor of NMR in Biomedicine (since 2010) and an editorial board member of Magnetic Resonance in Medicine (since 2015). He has served in numerous technical and scientific committees in professional societies, funding agencies and international conferences. Prof. Wu is an elected Fellow of International Society for Magnetic Resonance in Medicine (ISMRM) in 2013, Institute of Electrical and Electronic Engineers (IEEE) in 2014, American Institute for Medical and Biological Engineering (AIMBE) in 2011, and Hong Kong Academy of Engineering Sciences (HKAES) in 2018. He is the recipient of 2009 Outstanding Researcher Award from HKU, 2012 Croucher Senior Research Fellowship from Croucher Foundation, and 2018 Guanghua Engineering Science and Technology Prize.
He is an Honorary Professor at Departments of Medicine, Diagnostic Radiology, and School of Biomedical Sciences at HKU Li Ka Shing Faculty of Medicine.
