About the Department

The Department of Biology draws its strength from an exceptionally interactive and collaborative faculty, possessing a wide range of interests at all levels of biological organization, and utilizing many different biological systems and model organisms. Our faculty have received national and international recognition for contributions in genetics, neuroscience, development, population biology, plant biology, and other areas of specialization. Work being done in the department has broad implications for the treatment of disease and genetic anomalies, the preservation of endangered species, the development of food crops, and many other global problems centered in the life sciences.


The biology department has 49 full-time faculty members. Our large and thriving community also includes approximately 60 current pre-doctoral students, approximately 55 postdoctoral and research scientists, and nearly 700 majors (more than any other program in Arts & Sciences). Nearly all of our faculty have peer-reviewed grant support—now totaling around $12 million each year—and many hold leadership positions in the scientific community.


Washington University in St. Louis is fully committed to being a national leader in sustainability, a core priority that runs through all aspects of our community, our operations, and our work as a leading teaching and research institution. Explore how we are addressing climate change and environmental degradation.
