Dr Lu joined the University of Sheffield as a Lecturer in Machine Learning in November 2016. He has a PhD degree in Electrical and Computer Engineering from the University of Toronto, Canada, in 2008, and M.Eng. and B.Eng. degrees in Electrical and Electronic Engineering from Nanyang Technological University, Singapore, in 2004 and 2001, respectively.
Before joining Sheffield, he was an Assistant Professor with the Department of Computer Science, Hong Kong Baptist University, from 2013 to 2016, a Scientist with Institute for Infocomm Research, Singapore, from 2009 to 2013, and a post-doctoral fellow with the University of Toronto from 2008 to 2009.
- Research interests
Dr Lu’s current research focuses on machine learning, brain imaging, and tensor analysis. His research also covers related areas such as big data, biomedical engineering, computer vision, and signal/image processing.
His core expertise is tensor analysis and learning. He proposed several key tensor-based machine learning algorithms and lead-authored the book "Multilinear Subspace Learning: Dimensionality Reduction of Multidimensional Data" (CRC Press, 2013).
He contributed to applications including face/gait recognition for human identification and surveillance, video analytics for epileptic seizure detection, EEG classification for brain-computer interfaces, and fMRI data analysis and classification for brain state decoding.
