Minyoung Wyman

IMG_7958_2Former postdoc

Minyoung received a Ph.D. (2012) from the University of Toronto in Ecology & Evolutionary Biology (advised by Locke Rowe). Her dissertation examined how males and females evolve sexual dimorphism. Although males and females share many of the same genes, they may be under pressure to express them differently. It remains a puzzle how the genome adapts to this sexually dimorphic selection. For her postdoc, Min focused on determinants of variation in mutation rates in primates.
