HIROSHI AKASHI

Professor of Evolutionary Genetics, National Institute of Genetics (NIG)
Ph.D., Ecology and Evolution, University of Chicago, 1996

Professor Akashi’s research focuses on understanding the causes of genome evolution. In particular, his work has employed population genetic methods to identify mutations with subtle fitness effects such as changes at “silent” sites in DNA. Natural selection can have an important impact on the long-­‐term evolution of such mutations but the fitness effects may be too small to measure directly in the laboratory or in natural populations. A major goal is to determine whether weak selection is a prevalent factor in genome evolution and to address why this is the case. Dr. Akashi was educated in the United States (grade school through graduate studies) and moved from a faculty position in the Department of Biology at Penn State University to the National Institute of Genetics in Mishima in 2009.
