Meredith Schuman was born in Minneapolis, Minnesota, USA, and is currently leading a junior research group at the German Center for Integrative Biodiversity Research (iDiv), where she investigates the ecological roles of genes in populations of the wild tobacco plant Nicotiana attenuata. She hopes to find a tenure-track position in molecular chemical ecology when funding for her current position ends in 2017. Her hobbies include reading, writing, running, hiking, bodyweight training and travel, and she loves teaching.
