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 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.

  • One math course for which MATH 030 or higher is listed as a prerequisite
  • One upper division Environmental Science course taught by the Department of Natural Sciences (e.g., EA100KS, EA103KS, EA104KS)
  • One course in the history, philosophy, or ethics of science (e.g. HIST 082 HM, PHIL 103 PZ, PHIL 038 PO, PHIL 035 CM, ANTH 123 PO, HIST101AC PO, HIST 101E PO, BIOL 047 PO, HIST 081 HM)
  • NEUR 125 JT: Minds, Brains, and Programs

Six‡† Biology Elective courses, numbered 100 or higher, including at least three laboratory courses (indicated by the “L” subscript). The following courses also count as biology electives: CHEM177KS, NEUR 103 KS, NEUR 148L KS, NEUR 149 KS, NEUR 161 KS, NEUR 181 KS, SCI 119 CM. Other courses may count as well, please consult your advisor. Elective courses may not be double counted as foundation or breadth courses. 

Senior Thesis in Biology, complete one of the following options. Students must register their thesis plans with the Department of Natural Sciences during the spring semester of their penultimate year.

  • BIOL 191 KS , one-semester thesis in biology
  • BIOL 188L KS and BIOL 190L KS , two-semester thesis in biology
