Senior Computational Scientist — Division of Bioinformatics and Biostatistics
Roger Perkins received B.S. and M.S. degrees in nuclear engineering science in 1972 and 1974, respectively, from the University of Florida. He was a reactor physicist at General Atomics (GA) from 1974 to 1980, involved in research and development for the Gas Cooled Fast Breeder Reactor and various Department of Defense projects. From 1981 to 1984 he was the chief nuclear engineer at INESCO, a private company doing research and development on the Riggatron Compact Tokamak Fusion Reactor. He rejoined GA in 1984 where he was a program manager and nuclear codes specialist at the National Science Foundation’s new San Diego Supercomputing Center at the University of California, San Diego. He was the director of the U.S. Navy’s Advanced Scientific and Engineering Supercomputer Center from 1990 to1993.
From 1994 to 2008 Mr. Perkins managed NCTR’s scientific computing contract that encompassed IT systems, software development, biostatistics, and bioinformatics. He became an NCTR staff member in 2008, where he served as senior advisor in the Division of Biostatistics and Bioinformatics until 2018 when he assumed the position of Chief of the Biostatistics Branch. Mr. Perkins’ entire career has involved computational science — spanning physics, engineering, chemistry, and the biological sciences. He has been instrumental in promoting and advancing bioinformatics during his more than 24-year tenure at NCTR. He has served on several FDA governance boards and committees involving IT, scientific computing, and high-performance computing. He has been an FDA Scientific Computing Board member since its inception in 2007.
Mr. Perkins has served in various capacities, both administrative and research, since becoming a staff member in 2008. As both contractor manager and staff member at NCTR since 1994, he continually advocated for and fostered computational-science approaches in FDA research and regulatory sciences. While he was the scientific computing contract’s manager, he recruited some of the earliest bioinformaticists at NCTR, some of whom remain as senior scientists. Early research that preceded high-throughput molecular technologies was developing models to predict toxicity and biological activity based solely on chemical structure. Structure-activity relationship and chemometric-machine learning models were developed to predict which untested chemicals would exhibit endocrine activity mediated by nuclear receptors. Training sets were designed for diverse chemicals, and assays for those chemical’s binding to hormone receptors were run at NCTR; that data along with data from the literature formed NCTR’s first knowledge base anchored to endocrine-active chemicals.
The advent of microarrays and even more advanced sequencing provided opportunities for advancing research — and eventually precision clinical medicine — but not without computational challenges. Mr. Perkins participated in projects, including large international collaborations led by NCTR that focused on validating methods for discovering reliable biomarkers and predictive models from the extremely high-dimension molecular data, where false discovery risks are exceedingly high. Most recently, he has been involved with research projects employing Bayesian latent-variable methods, such as topic modeling for data modeling, labeling and information retrieval (including textual content), as well as developing text-mining software for regulatory-environment deployment.
