Description of Research

Our research is centered on unraveling the intricate interplay between metabolic diseases and tumour development, particularly within the context of the tumour microenvironment and stem cell niches. We leverage our multi-disciplinary expertise in the fields of cancer, stem cells, and bioengineering to explore and comprehend the fundamental mechanisms that underlie tumour initiation and progression in chronic liver diseases. Furthermore, we are keenly interested in investigating the biology of tissue-resident epithelial stem cells to pave the way for innovative regenerative medicine strategies. To address our basic biomedical questions, we adopt an integrative approach combining dietary-induced and genetically-engineered mouse models, tissue engineering techniques, as well as 3D organotypic cultures. Our work involves meticulously designing of sophisticated disease models, which provide a close representation of the intricate interplay of biological factors and signalling pathways found within human and mouse tissues. This allows us to simulate disease processes with a high degree of fidelity, enabling us to investigate the underlying factors and discover novel insights into disease progression and treatment.
