The development of tools to aid in the understanding of the exposure-dose relationship is a critical linchpin in elucidating the potential dangers an environmental contaminant may present. Bridging the gap between a recipient’s contact with a pollutant and the concentrations of that pollutant reaching the biological site of action are vital to assess the potential toxicity causes by an exposure. Christopher’s focus is to develop state of the science informatics tools to enable quick assessment of a chemical’s exposure-dose characteristics with particular emphasis on metabolic degredation.
