Our lab consists of evolutionary ecologists investigating how properties at the individual level translate into population and community dynamics. Our model systems include various taxons, such as insects, reptiles, small mammals and plants. We use genetic tools, evolutionary experiments and modeling to better understand the processes affecting the structure and function of natural ecological systems.
