Profile
I am the Founder and Lead of the AI in Medicine and Surgery (AIMS) Group at the University of Leeds, with over 15 years of experience in medical, biomedical, and surgical data analysis, specialising in medical imaging and computer vision.
My research focuses on developing foundational artificial intelligence methods for general medical/biomedical imaging, endoscopy, minimally invasive surgery, robotic surgery, and image-guided interventions, with an emphasis on clinically robust and generalisable systems.
I have been recognised among the Elsevier and Stanford World’s Top 2% Scientists (2023–2025). My work has also been supported by major competitive funding, including the Academy of Medical Sciences Springboard Award (2025), EPSRC New Investigator Award (2025), and Worldwide Universities Network (WUN) grants (2024–2025), enabling international and interdisciplinary collaborations.
Research Expertise
My research lies at the intersection of computer vision, machine learning, and medical image analysis, with a strong focus on translational healthcare applications. Key areas include:
-
Computational endoscopy and surgical vision systems
-
2D and 3D medical image analysis
-
3D reconstruction of endoscopic and surgical scenes
-
3D–2D fusion, registration, and cross-modal alignment
-
Segmentation, detection, and anomaly analysis in medical imaging
-
Surgical workflow and phase recognition
-
Surgical scene understanding, tracking, and reconstruction
-
Surgical tool detection and tool–tissue interaction modelling
-
Multimodal learning and domain generalisation
-
Depth estimation and robotic surgery scene understanding
I have developed several foundational methodological research in endoscopic and surgical computer vision and in general medical imaging (some works include US, CT, MRI, high-throughput imaging). I have authored nearly 40 peer-reviewed journals (mostly as first/senior author) and over 60 conference papers at top venues (IEEE Transactions in Medical Imaging, Medical Image Analysis, MICCAI and many others). Some of my pioneering works includes (but not limited to) 3D reconstruction of GI/surgical endoscopic videos (Barrett’s oesophagus, colonic scenes and surgical scenes), 3D-2D image fusion, 3D/2D segmentation methods, anamoly detection/segmentation (e.g., polyps, colitis scoring), surgical phase recognition, surgical scene segmentation, surgical scene tracking, tool detection and tool-tissue interaction, generalisation and multimodal modeling for various downstream tasks and more. I also led the frontier in establishing automated 3D to 2D laparoscopic fusion problem introducing several computer vision solutions to 2D and 3D anatomical liver landmark methods. My initiative of Preoperative to intraoperative fusion (P2ILF) is a landmark dataset and problem formulation which has been main stream research in AR research in robotic/laparoscopic surgery.
Key Contributions
I have contributed to several foundational problems in medical AI and surgical computer vision:
Endoscopic and Surgical 3D Vision
Developed methods for 3D reconstruction of gastrointestinal and surgical endoscopic videos, including applications in Barrett’s oesophagus, colonoscopy, and laparoscopic surgery.
Preoperative-to-Intraoperative Fusion (P2ILF)
Pioneered the P2ILF framework, enabling robust 2D–3D correspondence between preoperative imaging and intraoperative laparoscopic video. This work has established a key paradigm for augmented reality and image-guided surgery.
Multimodal and Generalisable Medical AI
Advanced methods for cross-domain learning and multimodal fusion to improve robustness across institutions, devices, and clinical environments.
Publications
I have authored approximately 40 peer-reviewed journal articles and over 60 conference papers at leading venues, including:
-
IEEE Transactions on Medical Imaging (TMI)
-
Medical Image Analysis (MedIA)
-
MICCAI
My work spans foundational methodological research and translational clinical applications.

Education and Early Career
I obtained my MSc (by research) in Computer Vision from the University of Burgundy, France (2010–2012), focusing on retinal image analysis in collaboration with Oak Ridge National Laboratory (USA) and Le2I, University of Burgundy.
I completed my PhD in Image Analysis (awarded 2016) at the University of Lorraine (CNRS–CRAN, France), where I developed computer vision methods for endoscopic video mosaicking and bladder cancer monitoring through robust feature tracking and motion-based reconstruction.
I subsequently held postdoctoral positions at:
-
University of Heidelberg & DKFZ, Germany (2015–2018), working on physics-based deformable multi-modal image registration and neuroimaging reconstruction
-
University of Oxford, UK (2018–2022), where I developed AI systems for computer-assisted endoscopy in collaboration with clinical partners at Oxford University Hospitals
I currently hold a Visiting Fellow position at the University of Oxford.
Research Vision
My long-term vision is to develop robust, generalisable, and clinically deployable AI systems that improve surgical safety, enhance decision-making, and enable intelligent, computer-assisted operating environments that benefit patients globally.
Supervision & Teaching
I supervise and co-supervise PhD students working on medical AI, including surgical vision, 3D reconstruction, and multimodal learning. I also support research training for students globally, including through volunteer academic roles.

Research interests
My research interest lies in solving computer vision and image processing related problems which includes building new mathematical models and implementation of the methods for both research purposes and practical use. I mostly work around applications in medical and biomedical image analysis and multimodal data analysis. I am keen towards learning about new technologies and open to meeting new people, establishing interesting and innovative collaborations (both academia and industry), mentoring students and looking forward for new and exciting opportunities.
I have an extensive experience in building cutting edge computer vision technologies for object detection, semantic segmentation, image restoration, depth estimation, optical flow, image registration and 3D reconstruction. I have developed tools in these topics with both classical mathematical models and deep learning models. I am a passionate researcher with knowledge, energy and enthusiasm to contribute towards healthcare technologies that can benefit patients and assist clinicians around the world. I am a promotor of translational research and equality in access to digital healthcare for all.
