I am a PhD candidate at School of Computer Science and Engineering, the University of New South Wales, supervised by Dr Lina Yao and Prof. Salil Kanhere.

My research focuses on developing robust and versatile spatial-temporal Learning algorithms for pattern discovery and knowledge mining in the multi-modal sequential data. My work is motivated and can be applied to various real-world applications such as Smart Cities (e.g., Intelligent Transportation), Healthcare (e.g., elder caring), Fintech, and Neuroscience (e.g., EEG).
