Think like a biologist.

As a biology major at Grinnell, the world is your laboratory. You’ll join other creative thinkers in an innovative program that encourages you to study multiple disciplines and think like a biologist from day one. You’ll conduct research, design and execute investigations, interpret data, and communicate your findings. As you explore a broad spectrum of sub-disciplines, you’ll enhance your ability to read and write scientific literature, think independently, work collaboratively, and prepare for advanced study or a career in medicine, research, education, environmental science, health, and many other fields.
