Research Interests
I work on systems and networking. I lead the NetX Lab. Welcome to visit us!
Our research is/was supported by funding from Research Grants Council (RGC) of Hong Kong, The Chinese University of Hong Kong, City University of Hong Kong, Huawei, Microsoft Research Asia, Azure, Amazon Web Services, etc.
Current Projects
ML systems: ML/AI is important, but infra and deployment support is often the bottleneck to real-world use
Sparse and adaptive computation, new computing paradigms must be explored to keep scaling our deep neural networks
Large-scale ML, faster, cheaper, and easier training and inference for large-scale ML workloads
Resource scheduling, schedule jobs and coordinate resources with maximum efficiency
Simulation, accurate and efficient performance simulation of distributed training
Related pubs: EMNLP’23, ATC’23, EuroSys’23, CoNEXT’18, SoCC’18
Networking: what would the future network look like?
Programmable dataplane, how can we better use the SmartNICs/DPUs?
ML-empowered network management, how can ML help reduce the human effort needed in network management tasks?
NetKernel, re-architecting network stack as part of the virtualized infrastructure
Video analytics, we need highly efficient video analytics pipelines for prevalent edge devices

Learning: we also study theory and algorithm on the side
Learning to Optimize (L2O), how can we leverage DL to help solve optimization programs?
Related pubs: CVPR’24, INFOCOM’24
