Caroline Johnson

Caroline Johnson has applied metabolomics to large-scale cancer epidemiological studies, identifying pre-diagnostic metabolic signatures that predict cancer risk years before clinical diagnosis. Her work on exposome-metabolome interactions has revealed how environmental exposures alter metabolic pathways to promote carcinogenesis. Her epidemiologic metabolomics approach integrating metabolite profiling with prospective cohort studies has provided causal evidence linking specific dietary and environmental metabolites to cancer development.
