Evolution, Ecology, and Organismal Biology

Welcome Message from Chair Joel L. Sachs

Welcome to the Department of Evolution Ecology & Organismal Biology (EEOB) at the University of California, Riverside!

The EEOB department is responsible for instruction of the Biology major -- consistently among the largest majors on campus. We teach classes ranging from molecular and cellular biology, to ecology, evolution, and physiology of living organisms.

What is EEOB?

Our department conducts research, teaching, and service in many areas of the life sciences, including animal behavior, behavioral endocrinology, biomechanics, cell biology, conservation biology, ecology, ecomorphology, evolution, genetics, physiology, population biology, systematics, and theoretical ecology. Our graduate program is also named EEOB and offers Master of Science and Doctor of Philosophy degrees, with an emphasis on the latter. We are also part of the Evolutionary Biology Joint-Doctoral Program with San Diego State University. In addition, our faculty and graduate students are affiliated with several interdepartmental graduate programs, including: Biophysics; Cell, Molecular, and Developmental Biology; Genetics, Genomics, and Bioinformatics; Biomedical Sciences; and Neuroscience. We also offer many opportunities for undergraduate research.
