Stephanie Wang
Hello!
I am an assistant professor in computer science at the University of Washington and co-director of the SyFI Lab (Systems for Future Intelligence).
If you are interested in distributed systems, systems for machine learning and data processing, programming languages, and/or how these topics fit together, please apply to the Allen School at UW and mention my name in your application.
My research focuses on building flexible, efficient, and large-scale systems for machine learning.
Our group builds open-source systems for applications such as LLM training and inference with the goal of maximizing performance for current workloads while also enabling future workloads.
I am an original author of Ray (Ray Core and Ray Data), which has been used to train ChatGPT, serve high-performance LLMs, and break the CloudSort 100TB record. I continue to develop the Ray ecosystem as member of the Ray TSC and as a software engineer at Anyscale, where I am currently working on Ray Direct Transport (RDT), an accelerator-native dataplane in Ray.
