Biology Major

Study living organisms in the laboratory, classroom and field.

As a biology major or minor, our curriculum will give you a broad background in biology while providing for specialization in your particular interest. 

You’ll also gain extensive experience in testing your own hypotheses and designing your own experiments. You will carry out scientific investigations in the lab, the field and the classroom.

Biology majors pursue graduate work in biology or the health professions, or enter careers in government, business, law, journalism, secondary school teaching, environmental consulting, conservation organizations or biotechnology.

Tropical Ecology Conservation

While studying abroad in Costa Rica, Isabel Ramos ’25 participated in a tropical ecology conservation program that stationed her at a regenerative dairy farm to investigate the impacts of rotational grazing on arthropod communities.

Studying Plant Physiology

Jacob Ligorria ’23 analyzed current scientific literature regarding telegraph plants, plants that move their leaflets very quickly, and identified the most prominent gaps in our understanding of leaflet motion to suggest future avenues of investigation.

What I love most about the biology major is its flexibility in allowing you to explore various topics. From conducting behavioral experiments with crickets to bird banding at the Bernard Field Station to learning how to use Python for conservation applications, I’ve gained experiences across diverse fields, ecosystems, and research techniques.

Faculty & Teaching

The Biology Department’s faculty members are actively engaged in research with students. The type of questions they ask are: 

Why do some organisms have a modified genetic code? Which proteins are responsible for Drosophila development? How do microbes function in inhospitable environments? What are the effects of habitat fragmentation on plant-pollinator interactions? How do plants withstand drought? How do neurons find their synaptic targets? How is climate change impacting marine food webs? How does biology influence gender identity? What genes control cnidarian development?  How are invasive species influencing local plant and insect communities? How do embryos build protective extracellular barriers? How does the immune response differ in mice that are susceptible to Mouse AIDS from those that are resistant?  How has selection influenced the physiology of organisms that have made the transition from marine to terrestrial life?

In biology classes, students become scientists and develop their own hypotheses and carry out studies to test those hypotheses. They learn how to tackle unsolved problems, analyze data, write scientific papers and present their results. Students gain a broad background in biology and also get to specialize in the scale of biology they are most interested in, whether it be genes or ecosystems or both.
