The Genetic Map Enters Its Second Century

The Genetics Society of America (GSA) Medal is awarded to an individual for outstanding contributions to the field of genetics in the past 15 years. Recipients of the GSA Medal are recognized for elegant and highly meaningful contributions to modern genetics and exemplify the ingenuity of GSA members. The 2015 recipient is Steven Henikoff, whose achievements include major contributions to Drosophila genetics and epigenetics, Arabidopsis genetics and epigenetics, population and evolutionary genetics, genomic technologies, computational biology, and transcription and chromatin biology. Among these achievements, Henikoff elucidated the mechanism for position-effect variegation, revealed a central role for variant histones in nucleosome assembly at active genes, and provided new insights into genome evolution. He has also developed widely used computational tools for genome and protein analysis and new strategies for mapping chromatin-binding sites.
