One of the first biology departments in the United States, the Johns Hopkins Department of Biology is home to 27 research laboratories investigating a wide range of biological problems, with the unifying goal of obtaining explanations in quantitative and molecular detail.

Biology department faculty train students pursuing bachelor’s, master’s, and doctoral degrees. Research in the biology department is also performed by postdoctoral fellows and research scientists. Students from our programs have reached the pinnacles of academic research, medicine, industry, and an array of other professions.
