About Xtra Computing Group

Xtra Computing Group is a research lab at the National University of Singapore (NUS), School of Computing.

We work on big data management systems, parallel and distributed computing, and cloud computing, with a particular interest in emerging hardware (GPUs, FPGAs, etc.) and the intersection of systems and machine learning.

Research Areas​

  • Big Data Management Systems — scalable data processing, query engines, and storage systems built for the cloud and modern hardware.
  • Parallel & Distributed Systems — high-performance computing across heterogeneous and distributed environments.
  • Federated Learning — privacy-preserving, collaborative ML on non-IID and vertically partitioned data.
  • LLM Systems & Privacy — infrastructure and evaluation tools for large language models, including data privacy assessment.
  • GPU-Accelerated ML — libraries and frameworks that exploit GPU parallelism for classical and modern ML algorithms.

Join Us​

We welcome undergraduate interns, PhD candidates, and postdoctoral fellows to join our collaborative research environment.
