Justin Vaughn received his doctoral degree from the University of Tennessee, Knoxville, working with Albecht von Arnim to develop computational pipelines for comparative transcriptomics in plants. As a postdoctoral researcher in Jeff Bennetzen's lab at the University of Georgia, Athens, Dr. Vaughn characterized structural variation in rice populations and used this data to develop new models of tandem duplication formation. He also assisted on numerous genome sequencing projects ranging from orphan grains to culinary herbs. He moved to Zenglu Li's group at the University of Georgia as a postdoctoral researcher and then research scientist. There, he helped in efforts to characterize the global soybean germplasm as well as dissect the genetic architecture of key agronomic traits such as seed composition. He has additionally consulted on the design of the Noble Foundation’s Alfalfa Breeder's Toolbox, which aims to enhance the usefulness of genomic and phenotypic information in cultivar development. He has spoken at numerous academic conferences and given talks internationally for the Health and Safety Institute (HESI) on genetically modified crops.  He joined GBRU in early 2017.
