The Clay Lab at Indiana University

 

In our lab, most research focuses on interspecific interactions, particularly symbiotic interactions. We are interested in how specific symbiotic interactions affect larger scale ecological and evolutionary processes. A variety of systems from vertebrates to bacteria are utilized, with an emphasis on plants and arthropods.
