Lorenz Rhomberg is a Principal at Gradient, an environmental consulting firm in Cambridge, MA. He is nationally recognized for contributions to methodology and science policy in human health risk assessment, especially in the areas of animal-to-human extrapolation of toxic effects, and weight-of-evidence analysis. On behalf of the public and private sectors, he has conducted and published dose-response analyses for a number of high-profile risk assessments of industrial chemicals (including methylene chloride, formaldehyde, trichloroethylene, and ethylene oxide) in which novel analytical approaches are addressed to revise national-level environmental exposure standards.
