Biology

If you’re fascinated by organisms at any scale and wonder how life works, a Biology major could be a great fit

About Our Biology Program

  • Learn the foundational principles of biology and develop critical thinking and analytical skills as you generate hypotheses and test them through hands-on experimentation.
  • This major aims to equip students with the tools to engage with biological issues at all scales of organization, from molecular to ecological, and emerge as leaders in environmental, biotechnology, and health-related fields.
  • Complement your understanding of biology through study abroad programs, such Pitzer in Costa Rica, which includes both environmental and health options.
  • Many biology majors broaden their understanding by pursing a combined major with a discipline in arts, humanities, or social sciences, including Environmental Analysis.
  • The Biology program can prepare you for a wide variety of career options in molecular, environmental, or health fields.
  • As a Biology major, you’ll take classes and conduct research with world-class faculty from Pitzer and Scripps colleges through our Department of Natural Sciences. Stipends are available for summer research.
  • You’ll be able to take advantage of labs, classrooms, offices, and even a community greenhouse in the 65,000 square-foot Nucleus, our brand-new science building.

Biology & Our Values

Interdisciplinary Learning

Pitzer's program is interdisciplinary, encouraging students to connect different fields to the study of biology.

10 Fields of Study

Biology majors can receive credit toward their major by taking courses in up to 10 different disciplines, from chemistry to computer science.

Environmental Sustainability

Pitzer Biology students have helped restore hundreds of acres of rainforest at Pitzer’s Firestone Center for Restoration Ecology in Costa Rica.

Learn More about the Firestone Center
93% Percentage of restored land cover

In 1993, when the Firestone Center opened, its land cover was just 8%. Over the past 30 years, Pitzer students have helped restore rainforest and bring native species back to this part of Costa Rica's lowland rainforest.

Pitzer Voices

“I was able to go on a boat with eight other researchers and an ROV team, a remotely-operated vehicle team, for a week. ... We were launching the ROV in the morning to take pictures, record video, and collect samples of corals ... to use for genetic studies in the lab.”

Research

Max Richmond ’23 helped research a “selfish chromosome” that changes the sex of jewel wasps from male to female. His work will help scientists understand how — and why — this chromosome takes over the jewel wasp’s genome.

Biology Program Details

View Course Catalog

Biology is the study of the entire process of life, its beginning, its development and reproduction, and its cessation and decay. 

What You Will Learn

  1. How to understand foundational scientific principles and findings in biology.
  2. How to think critically and analytically by developing specific hypotheses and testing them with controlled experiments.
  3. How to read, understand, and critique original research articles.

The major in Biology requires the completion of at least 14 courses and a senior thesis.
