Research in the Department of Biology spans the entire breadth of biology: from ecology and evolution to molecular, cellular, and developmental biology. Our research is supported by a wide array of funding sources, including NIH, NSF and the Welch Foundation.

Many departmental faculty members actively participate in campus-wide interdepartmental graduate and research programs, including Genetics, Neuroscience, Molecular and Environmental Plant Sciences, and the newly formed faculty of Ecology, Evolution, and Behavioral Biology.
