Gregory M. Blumenthal, PhD, obtained his B.A. in Chemistry from Vanderbilt University and his doctorate in Pharmacology from Duke University. He has produced a body of work of enormous depth and breadth, encompassing research in toxicology, risk analysis, secure financial web applications, and other data science projects for such agencies as NIH, EPA, the VA, and NASA (from whom he received an award in 2014). His presentation developing objective criteria for PBPK models was expanded into the 2006 US EPA criteria for application of PBPK models to risk assessment. His specific contributions to the realm of statistical analysis continue to influence scientific analysis to this day. The August 2018 US FDA Guidance for acceptance of PBPK models in support of drug evaluations was based upon this US EPA document. Dr. Blumenthal’s strongest area of expertise is data science and data analysis, providing quantitative evaluation and GIS consulting services to Memphis-area nonprofits, government agencies, and political campaigns.
