Dr. Andersen is a scientist at the Hamner Institutes for Health Sciences. His research focuses on developing biologically based models for the uptake, distribution, metabolism, and biological effects of drugs and chemicals and their application to safety assessments and quantitative health risk assessments. In recent years, his research emphasis has been on developing mathematical descriptions of control of genetic circuitry and the dose-response and risk-assessment implications of these control processes.
