Michael Wray

Assistant Professor of Computer Vision

I am a lecturer/Assistant Professor of Computer Vision at the School of Computer Science at the University of Bristol. My research interests are in multi-modal video understanding, particularly for egocentric videos — focusing on how both vision and language can be tied together towards tasks such as cross-modal retrieval, grounding and captioning. I am part of MaVi and ViLab.

Short Bio

Michael is a lecturer in Computer Vision at the School of Computer Science at the University of Bristol. He finished his PhD titled "Verbs and Me: an Investigation into Verbs as Labels for Action Recognition in Video Understanding" in 2019 under the supervision of Professor Dima Damen. After, he stayed in the same lab as a Post-Doc working on Vision and Language and the collection of the Ego4D Dataset. Michael has led the organisation EPIC workshop series from 2021 onwards, is an organiser of the Ego4D workshop series, and is an ELLIS member.
