Dr. Everett is a scientist in the US EPA Center for Computational Toxicology and Exposure (CCTE) with a wealth of expertise in bioinformatics, computer science, genomics, statistics, genetics, and molecular biology. His research at CCTE is focused on advancing the application of high-throughput transcriptomics in chemical screening. He received a B.S. in Computer Science from Binghamton University and a Ph.D. in Genomics and Computational Biology from the University of Pennsylvania, followed by extensive post-doctoral training in various applications of ‘omics data analysis. Prior to coming to the US EPA, Dr. Everett worked as a Senior Bioinformatics Scientist at Sciome, LLC where he helped support research under the National Toxicology Program.

Abstract for OpenTox Summer School 2023

Dose-Response Modeling for Determining Transcriptomic Reference Values

There is increasing interest in the application of dose-response modeling approaches to broad/non-targeted profiling data, such as transcriptomics, in order to derive mechanism-agnostic reference values for potentially hazardous chemicals. In this session, I will present an overview of existing approaches to dose-response modeling of transcriptomic and other high-dimensional data sources as well as possible regulatory use cases, including the recently proposed EPA Transcriptomics Assessment Product (ETAP, see A demonstration will then be presented with the widely used open-source platform BMDExpress.
