My main interest lies in constructing quantitative measures for characterizing disease related tissue abnormality and damage using all available information sources including but not limited to bioimaging modalities, genomics, proteomics, as well as clinical history. In particular, I investigate the effects of tissue abnormality and damage associated with degenerative diseases like cancer on the appearance observed by radiological images as the macro scale and histology slides at the micro scale and to the molecular scale presentation as characterized by gene and protein sequences, gene expression profiles, and metabolite concentrations. The correlations between these appearances across macro, micro, and molecular scales reveal a much more complete picture of the cumulative degeneration and abnormality induced on the affected tissue by a disease process, allowing to predict one based on the others, and collectively depict the scope of the abnormality for diagnosis and staging, as well as prognosis and the most suitable therapeutic strategies.
