BingKan Xue currently works in systems biology and studies evolution from a theoretical perspective. He is interested in the phenomena of phenotypic variations and transgenerational inheritance among biological populations in response to changing environments. The ability to switch phenotypes under environmental stress allows individual organisms to increase their chance of survival on short time scales. The population of individuals with switching rates better adapted to the statistics of the environment has higher fitness under natural selection on long time scales. A theoretical framework of how the switching patterns evolve on different time scales may explain the rise of various hereditary mechanisms observed in nature.
