Jim Seeb is a geneticist whose research focuses on identifying genetic differences that distinguish one Pacific salmon population from another. He currently has projects to use genetic markers to track the migration of adult salmon in the North Pacific Ocean and Bering Sea. Students and post docs in the Seeb Lab are creating genetic maps to enable genomic study of Chinook, sockeye, pink, and chum salmon and steelhead trout. These maps also accelerate discovery of genes that control adaptively important traits. Jim and his wife, Lisa Seeb, cooperatively run the program which provides an important intersection between the Alaska Salmon Program and the SAFS Molecular Ecology Research Laboratory to conduct both basic and applied research. A newly developing goal of theirs is to better understand the genetic mechanisms underlying how salmon respond to environmental change by placing their abundant genotype information into an ecological context.
