Biography

Dr Hyung Jin Chang is an Associate Professor in the School of Computer Science at the University of Birmingham and is affiliated with the Institute of Data and Artificial Intelligence (IDAI). He was also a University Turing Fellow of the Alan Turing Institute, the UK’s national institute for data science and artificial intelligence.

He received his BSc in Electrical and Computer Engineering and PhD in Electrical Engineering and Computer Science from Seoul National University in 2006 and 2013, respectively. Before joining the University of Birmingham, he worked as a Post-Doctoral Research Associate at Imperial College London, where he participated in several European research projects focusing on computer vision, machine learning, and human-robot interaction.

Dr Chang’s research lies at the intersection of artificial intelligence, computer vision, robotics, and human-robot interaction, with a particular emphasis on human-centred AI. His work aims to build intelligent robotic systems capable of understanding human perception, action, and intention through visual and multimodal learning.

He is especially interested in human-centred visual learning, including the estimation of human hand pose, body pose, and gaze, and the modelling of human actions and internal states. His broader goal is to advance robot vision and learning for intelligent and natural human–robot interaction.

His research has been supported by national and international funding agencies and industrial partners, and his work has appeared in leading venues such as CVPR, ICCV, ECCV, ICRA, IROS, NeurIPS, and AAAI. He also serves regularly as Area Chair and reviewer for top-tier AI and robotics conferences. He is currently an Associate Editor of IEEE Transactions on Pattern Analysis and Machine Intelligence (TPAMI).

Postgraduate supervision

Dr Chang supervises doctoral research in the following areas:

Human-centred AI and visual learning
Computer vision for human understanding
Robot perception and dexterous manipulation
Human–robot interaction

He welcomes PhD applicants interested in the intersection of computer vision, robotics, and human-centred intelligence.

Research

Dr Chang’s research combines artificial intelligence, computer vision, and robotics to enable intelligent and interactive robotic systems. His work explores both fundamental visual learning problems and applied robotic perception.

Research themes

Human-Centred Visual Learning – Modelling human perception and behaviour through hand, body, and gaze estimation
Robot Vision and Dexterity – Enabling robots to perceive and manipulate objects intelligently in dynamic environments
Multimodal Learning for Interaction – Integrating vision, touch, and force information for adaptive and safe robot control

He collaborates closely with industrial and academic partners and contributes to UK and EU-funded research programmes on intelligent robot perception.
