Research Themes

Spatially-Aware Deep Learning for Histopathological Tissue Characterisation

Combining pathology expertise with proficiency in machine learning and computational image analysis, I developed and led projects building quantitative, automated tools for histopathological tissue assessment that access biological information beyond the reach of manual review. My most significant contribution was a weakly supervised deep learning framework that predicts DNA content abnormalities, a key molecular marker of cancer progression, directly from routine H&E whole-slide images of Barrett’s oesophagus biopsies, introducing a novel multi-instance learning augmentation strategy that substantially improved model performance. I further developed AI(H), a multi-task deep learning model for comprehensive histological assessment of autoimmune hepatitis that characterises multiple tissue compartments and pathological features from routine staining, providing spatially resolved, quantitative, and interpretable tissue profiles that improve reproducibility. Complementing these tools, I contributed to establishing an expert consensus morphological framework for standardised tumour-infiltrating lymphocyte assessment in gastro-oesophageal carcinomas, defining the evaluation criteria required for clinical validation of immune biomarkers in this cancer type.

Spatial Profiling of Immune, Stromal, and Tissue Features for Cancer Progression Risk

I established a programme of work linking computational spatial profiling to cancer progression biology across multiple cancer and precancer systems. In my primary PhD project, I pioneered the computational characterisation of the spatial immune microenvironment in hepatocellular carcinoma, developing a deep learning pipeline that classifies tumour immunophenotypes from immunohistochemistry slides and demonstrating that computationally derived immunophenotypes carry prognostic significance. In a parallel project, I co-led a study establishing that stromal activation in colorectal cancer drives immune microenvironment remodelling toward an immunosuppressive state, linking stromal biology to immune tolerance and adverse prognosis. My most advanced contribution in this area is BEACON, a spatially aware integrative framework that jointly characterises molecular abnormality and spatial immune ecology from routine Barrett’s oesophagus histopathology, enabling integrated cancer risk stratification from routine pathology images. I further contributed to identifying a morphometric tissue composition signature predicting freedom from invasive progression in ductal carcinoma in situ, demonstrating the generalisability of computational spatial profiling for precancer risk assessment.

Clonal Evolution, Tumour Heterogeneity, and Tissue Dynamics in Carcinogenesis

By integrating expertise in histopathology, molecular pathology, and translational research, I conducted and contributed to several studies investigating the molecular dynamics of tumour heterogeneity, clonal evolution, and tissue cell fate across carcinogenesis and organ regeneration. In the most conceptually significant of these contributions, I provided the first genomic demonstration that focal nodular hyperplasia, a hepatic lesion regarded as definitively benign, can give rise to hepatocellular carcinoma through clonal selection, establishing a shared genomic ancestry between the precursor lesion and the adjacent carcinoma. I further contributed to the molecular dissection of intra-tumoral heterogeneity in pulmonary pleomorphic carcinoma through multi-region profiling of histologically distinct tumour components, establishing the evolutionary relationships between tumour components and the molecular programs driving their divergent phenotypes. Extending this to regenerative biology, I contributed to the discovery of bipotent transitional liver progenitor cells, demonstrating through dual genetic lineage tracing that a biliary cell-derived progenitor population retains the capacity to adopt either hepatocyte or biliary fate during severe liver injury.
