Our Research


We develop innovative biomedical imaging instruments and methods to study light–tissue interactions, aiming to answer fundamental biological questions and address widespread diseases, with a particular focus on cancer. Biophotonics, the science and technology of generating, detecting, and manipulating light in biological systems, is a transformative force in modern biomedical research. Our work sits at the intersection of multiple disciplines, including microscopy, spectroscopy, spatial biology, advanced endoscopy, and artificial intelligence. We apply advanced imaging and spectroscopic techniques, including multidimensional correlative imaging, to both preclinical disease models and patient studies, providing new insights into disease onset and progression. Our biophotonics laboratories at Guy’s Hospital are fully equipped with state-of-the-art label-free imaging platforms, including multi-photon and fluorescence lifetime imaging, confocal and conventional Raman microscopy, fiber-optic Raman spectroscopy, hyperspectral imaging, DESI-mass spectrometry imaging, and endoscopic/laparoscopic imaging systems. We work closely with clinical partners to translate these technologies into real-world healthcare settings.

The key research interests of the group fall within 3 complementary topics:

  • Multidimensional molecular imaging
  • Artifical intelligence enabled biophotonics.
  • Biophotonic applications in regenerative medicine and in vivo translation

Multidimensional molecular imaging


We develop innovative instruments and technologies for multimodal bioimaging at the molecular level. In label-free bioimaging, the detected light arises directly from the interaction between the excitation light and the biological sample. These interactions can trigger a range of physical processes, including scattering, absorption, and fluorescence decay. .


Our laboratory focuses on developing advanced correlative imaging approaches that combine multi-photon microscopy, fluorescence lifetime imaging, confocal Raman spectroscopic imaging, and optical coherence tomography. We further integrate optical spectroscopy with cutting-edge molecular profiling techniques, including Desorption Electrospray Ionisation (DESI) mass spectrometry imaging (MSI) and spatial transcriptomics, to achieve a comprehensive view of biological systems.

Artifical intelligence enabled biophotonics.


Artificial intelligence (AI) has seen a rapid surge in interest and breakthroughs across diverse fields, including natural language processing, computer vision, reinforcement learning, and autonomous systems. In biomedical research, label-free bioimaging provides powerful, non-invasive analysis of biological samples, such as live cells and tissues, without the need for exogenous contrast agents.


We develop advanced AI approaches tailored to label-free bioimaging and biophotonics, enabling enhanced imaging fidelity, accelerated analysis, and improved diagnostic capabilities.

Development of clinical biophotonics technologies for early in vivo diagnosis of diseases


Early detection and intervention are critical to reducing cancer-related mortality. Emerging cost-effective biophotonic approaches for in vivo molecular analysis have the potential to transform clinical healthcare. Next-generation cancer diagnostics will rely on technologies capable of detecting, grading, and staging lesions at the earliest stages of disease.

Our approach integrates optical imaging, spectroscopy, and optical coherence tomography (OCT) to develop systems for comprehensive characterization of early-stage cancer. We believe that a multimodal imaging strategy, such as simultaneous Raman spectroscopy and OCT, has the potential to become the next-generation technology for in vivo cancer diagnostics. The clinical applications of Raman spectroscopy are already showing significant promise, including in the in vivo diagnosis of cancers, osteoarthritis, and monitoring tissue-engineered implants. Additionally, our lab actively investigates the fundamental mechanisms of light-tissue interactions to enhance our understanding of light transport in biological tissues.
