Jonatan Isaksson is a final year master’s student in evolutionary ecology at Linnaeus University. His master’s thesis investigates the genetic basis of spring and autumn leaf phenologies in the Swedish population of Quercus robur. More broadly, his interests are focused on understanding ecological drivers of differentiation in various species. Prior to his current academic pursuits, he worked for the United Nations Office on Drugs and Crime producing reports on the socioeconomic aspects of opium cultivation and holds a master’s degree in marine geography.
