Dr. Andersen has held a number of key positions over a 45 year career in toxicology and risk assessment, including Chief Science Officer at The Hamner Institutes for Health Sciences and Professor of Environmental Health at Colorado State University.

Between 1971 and 1998, he worked in toxicology research programs in the US federal government (US DoD and US EPA) and private industry (Chemical Industry Institute of Toxicology and ICF Kaiser). He has conducted important work on developing biologically realistic models of the uptake, distribution, metabolism, and biological effects of toxic chemicals and drugs and applying these models in quantitative health risk assessments, and is widely recognized as one of the key individuals who brought physiologically based pharmacokinetic (PBPK) modeling into more common usage in chemical risk assessment.  Dr. Andersen has published over 500 papers and book chapters, and received the Lehman and Merit Awards from the US Society of Toxicology and the Mildred S. Christian Award from the Academy of Toxicological Sciences in recognition of his contributions.
