Biological & Environmental Engineering

We bring life to engineering

Our unique focus to design and develop processes, products and systems using basic biological, environmental science and engineering tools generates solutions to societal problems involving water, food, energy and public health. Students increasingly need to participate in problem-solving across traditional boundaries. Rapid technological changes are an added challenge, with implications driven by diminishing resources and a growing population. We aim to enable our students to drive innovation as our discipline continues to be transformed by our changing world.

About our department

Welcome to the Department of Biological and Environmental Engineering (BEE) in the College of Agriculture and Life Sciences. Our department is one of the largest of its kind in the country, with a very diverse faculty, staff and student population. We serve three integrated functions: teaching the next generation of undergraduate and graduate students, research on problems in biology and the environment, and public outreach to help society implement new knowledge.
