Eivind A. B. Undheim is an evolutionary biologist interested in the molecular processes that drive the evolution of traits and how these processes affect each other across levels of biological complexity. He is especially interested in the biology and evolution of animal venoms, which are fascinating and key adaptive traits for a wide range of animals that provide opportunities for studying evolutionary innovation and novelty at levels that range from morphology to molecules. His research group at the University of Oslo, Norway, currently uses a wide range of venomous animal lineages to investigate the molecular basis of evolvability and genomic mechanisms underlying the evolution of novel traits.
