Biography

Currently I am a fourth-year Ph.D. student of College of Computer Science and Technology, Zhejiang University. Before my Ph.D. career, I was an undergraduate student from Wuhan University of Technology and received my B.Eng. degree in Computer Science and Technology on June, 2019. In September 2019, I was admitted to study for a Ph.D. degree in Zhejiang University under the supervision of Prof. Shuiguang Deng without entrance examination. [CV] [简历]

From Sep. 2022 to Aug. 2023, I am a joint PhD student at Nanyang Technological University (NTU), Singapore, under the supervision of Prof. Xueyan Tang.

Research Interests

Currently I am focusing on Cloud & Edge Computing, Distributed Computing & Systems, and Algorithm Design & Analysis. Recently, I pay great attention to the following topics:

• Resource Allocation & Job Scheduling Algorithms with Theoretical Guarantees
  Efficient scheduling is a key to the performance of applications in distributed systems. I am interested with the design and analysis of scheduling algorithms for large-scale clusters, DCs, cluster federations, etc. Currently I put special effort on combinatorial algorithm design and analysis for online scheduling problems.
• Ready-for-Use Cluster Schedulers in K8s-Native Systems
  K8s (Kubernetes) is an open-source operating system for automating the deployment, scaling, and management of containerized applications. Kube-scheduler is the default component responsible for the scheduling of pods (a set of inter-related containers). By leveraging the power of CRD (Custom Resource Definition), customer schedulers can be designed. I am interested with the R&D of custom schedulers for various batch & elastic workloads.
