Project I establishes an anticipatory framework for chemical hazard prioritization using data-driven models applied to under-characterized chemical space. Project II develops a computational strategy for prioritizing antidote candidates under experimental constraints by integrating efficacy, central nervous system accessibility, and synthetic feasibility. Project III establishes an integrated modeling framework for microcystin-LR hazard characterization that links external exposure to internal dose metrics to support cross-species interpretation relevant to human safety. Collectively, this work illustrates how computational approaches can support forward-looking, decision-relevant toxicological assessment across the chemical life cycle.106en-USchemical hazard identificationin silico drug designPBPK-BMD integrationThesis
