About Rui

I am a Research Scientist in Artificial Intelligence working within the DistributedAI group at Samsung AI Centre in Cambridge, UK. My research focuses on efficient inference and fine-tuning of large language models and stable diffusion models in resource constrained environment. In the past years, I have worked on a number of different machine learning paradigms including meta-learning, few-shot learning, and federated learning, and applications of these in different domains such as vision recognition and wireless mobile communications.

Prior to Samsung AI, I obtained my PhD on communications and deep learning from the School of Informatics, University of Edinburgh, in 2019. I was advised by Prof Paul Patras. During my study, I visited INRIA Lyon in France to work on reinforcement learning for mobility control of fleet of drone base stations in emergency networking, and I interned with the 5G research group at Samsung Research Institute UK (SRUK).
