Long Chen

I work on AI and computational imaging, with a particular focus on Robust AI and Efficient AI, with applications in underwater vision and medical imaging. My research aims to develop AI models that maintain reliable performance under challenging real-world conditions, including image degradation, noise, and domain shifts, while reducing computational and energy costs.

Bio

I am currently a researcher at Imperial College London, working with Prof. Declan O’Regan and Prof. Wenjia Bai. Before joining Imperial, I was a Research Fellow at University College London with Dr Thomas Dowrick and Prof. Matt Clarkson, and a member of the UCL WEISS Centre, led by Prof. Danail Stoyanov. I completed my PhD at the University of Leicester under the supervision of Prof. Huiyu Zhou and Prof. Junyu Dong. My research interests lie in AI and computational imaging, with a particular focus on Robust AI and Efficient AI.

Research Interests

My research focuses on robust and efficient AI, developing models that maintain reliable performance under challenging conditions while reducing computational and energy costs. My work spans visual perception and computational imaging, with applications in underwater vision and medical imaging.

Robust AI

Developing models for visual perception and computational imaging that maintain reliable performance under image degradation, noise, and domain shifts. My research encompasses object detection, image reconstruction and enhancement for underwater vision, as well as generative AI for medical data synthesis, 3D anatomical modelling, and disease progression prediction in healthcare.

Efficient AI

Developing computationally efficient and energy-efficient models through brain-inspired computation, network pruning, model compression, and lightweight architectures. My research aims to enable low-power learning and inference on resource-constrained platforms, such as autonomous underwater vehicles (AUVs) and drones, with a particular focus on underwater embodied intelligence.
