About

I am a postdoctoral researcher in the Cyber Physical Systems group at the University of Oxford, working with Niki Trigoni and Andrew Markham.

My current work focuses on multi-sensor world models and make them sustainable to deploy while reducing storage, communication, and inference costs between edge devices and servers. I also have a strong interest in improving multi-sensor representations and verifying whether agents ground their outputs in the correct physical evidence within their chains of reasoning.

I obtained my D.Phil. (PhD) in Computer Science at the University of Oxford, co-supervised by Profs. Niki Trigoni and Andrew Markham in the CPS group. Prior to my D.Phil., I worked as a research associate supervised by Prof. Yong-Guk Kim at Sejong University, South Korea, where I completed my master's and undergraduate courses in Computer Science.
