Department of Ecology, Evolution, and Organismal Biology


Welcome to the Department of Ecology, Evolution, and Organismal Biology (EEOB) at Iowa State University.

EEOB has many active research programs and opportunities for student interest in conservation biology, ecological and evolutionary genomics, population, community, and ecosystem ecology, quantitative genetics, and other traditional organismal disciplines such as taxonomy. 

Faculty in EEOB are linked through students and research programs to many other departments within the life sciences, as well as to supporting disciplines in the physical and computational sciences.  The diverse knowledge of the EEOB faculty provides unique opportunities for undergraduate students majoring in Biology, Genetics, and Environmental Science, to whom we offer a rich and cutting-edge curriculum.

If you have any questions about programs or opportunities in EEOB, please contact us at 515-294-0133.  We look forward to serving you.
