Majoring or minoring in biology acts as your gateway to a richer understanding of living organisms, from the molecules within cells to the biosphere that encompasses all of Earth’s ecosystems. At Southwestern, you’ll deepen your knowledge of molecular processes, ecological diversity, genetics, the human body, and evolution through our rich and wide-ranging curriculum. You’ll engage in thoughtful assignments and projects while gaining hands-on experience in our state-of-the-art on-campus laboratories. You will have opportunities to conduct research and collaborate with our engaged and enthusiastic faculty on a range of projects, such as studying

diversity & distribution of snails using genetics and field sampling
DNA repair & mutation
development & progression of breast & uterine cancer
gene expression within bacteria
complexities of antibiotic resistance
relationships between natural selection & gene evolution
ecology of local amphibians
development of neural circuits in the brain
response & impact of climate change on terrestrial ecosystems

Majors may choose to pursue either a bachelor of arts or a bachelor of science. Our students often take courses in SU’s robust Environmental Studies Program or elect one of our new interdisciplinary minors, such as Animal Studies, Health Studies, and Data Science. In addition, SU offers pre-professional pathways in the areas of pre-medicine, pre-dental, and pre-veterinary medicine that will provide you with personalized advising and other helpful resources that will prepare your for advanced study. No matter which path you choose, you will have numerous career choices from which to choose. Our alumni have gone on to successfully complete graduate and professional programs in the dental, medical, medical technology, nursing, optometry, pharmacy, and veterinary fields. They’ve also enjoyed satisfying careers in industry, government, nonprofit organizations, public health, and education.

Five women scientists had the opportunity to extend their coursework and research experience outside the classroom with poster presentations at the Texas Conservation Symposium, co-sponsored by Southwestern and The Williamson County Conservation Foundation. The students all had the opportunity to interact with the keynote speaker, Dr. Kelly Rameriz, Assistant Professor at the University of Texas El Paso and co-founder of 500 Women Scientists.
