Johannes Jäger is an evolutionary systems biologist and philosopher, originally trained as a Drosophila geneticist and modeller of biological regulatory networks. He was a group leader at the CRG Barcelona, a fellow of the Wissenschaftskolleg zu Berlin, and the director of the Konrad Lorenz Institute for Evolution and Cognition Research (KLI) in Klosterneuburg, Austria. He is a recurrent guest lecturer in evolutionary system biology at the University of Vienna, and the D’Alembert Research Chair 2020/21 at the Institut d’Études Avancées (IEA) Paris.

Johannes’ research interests are (the evolution of) complex regulatory systems, organismic agency, and innovation in evolution as well as academic research. He is an advocate of “open science.” Some of his projects combine arts and science. He also develops transdisciplinary workshops with unusual formats that focus on collaboration and sharing of information between researchers from different fields.
