About

Dr. Uchimura joined RERF in April 2017 as a laboratory chief of the Molecular Genetics Laboratory. He studied theoretical population genetics during his master’s degree in graduate school and became interested in de novo germline mutations. Since his PhD course, he has investigated the rates and characteristics of various de novo germline mutations and their health effects on later generations by using animal model. Recent advances in next-generation sequencers have made it possible to analyze de novo mutations on a genome-wide scale. His research group will use state-of-the-art sequencing techniques to analyze the survivors of the atomic bomb and their children, to clarify the molecular features of the biological effects of radiation exposure, especially the genetic effects on the next generation.
