Research Interests

I am interested in any issues in parallel and distributed systems or developing parallel and distributed computing techniques for application scenarios of any kind. I have published over 190 papers in top venues such as IEEE TC, TPDS, TKDE, TCSVT, NeurIPS, SC, EuroSys, IPDPS, ICPP, HPCA, VLDB, Micro, DAC and so on. My current research is in parallel or distributed machine/deep learning (e.g. federated learning, acceleration of Graph Neural Networks training), AI for Science (e.g., Improving training performance for Physics-Informed Neural Networks), cluster, Cloud and edge computing (e.g., optimising workload and resource management solutions), parallelized/distributed data analytical methods (e.g., anomaly detection for time series data, deep learning methods for point clouds, pattern discovery for big data), miscellaneous issues in parallel and distributed systems (e.g., optimized communication schemes in distributed systems, security-restrained high performance computing).

I always look for motivated PhD or MSc-by-research students who have the interests in doing research in the above areas. Please feel free to contact me.
