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 interdisciplinary graduate research programs, including Genetics & Genomics, Neuroscience, Molecular and Environmental Plant Sciences, and Ecology & Evolutionary Biology.

Peter Rizzo

Peter Rizzo joined the Biology Department faculty in 1975 teaching cell biology and working in his lab until retirement in 2008. His research focused on the diverse group of unicellular algae known as dinoflagellates, the only eukaryotes that completely lack histones. He currently resides in Tennessee.

Merrill Sweet

An insect ecologist, Dr. Sweet came to the Biology Department of Texas A&M University in 1963, became Professor in 1982, and Professor Emeritus of Biology in 2003.
