Biological Engineering Major

Practical, solution-oriented engineering.

A hands-on approach to an engineering education with real-world challenges and sustainability always at the forefront. Grads take leadership roles in manufacturing organizations, engineering firms, nonprofits, and government agencies, and continue on to success in graduate school.

Penn State Engineering. Penn State Ag. Enjoy the best of both worlds.

This is a Penn State engineering degree. You'll benefit from the rigor, depth, prestige, and enormous resources of the College of Engineering and the College of Agricultural Sciences.

Our focus is creating solutions to sustainability challenges in food production, biological processing, and natural resource protection. World-class faculty move from behind the podium and challenge you to roll up your sleeves and harness engineering principles to make our food, fiber, and water systems and products more efficient, sustainable, and healthy, and less wasteful.

Biological Engineering is the right major if you’re: 

  • interested in applying engineering skills and analyses to biological systems
  • looking to advance technology to improve production
  • passionate about stewarding the environment

Out of the classroom and into the world.

At Penn State, there are more opportunities to learn, meet professionals working in your field, network, and have more fun than you can imagine.

The same goes with our internship opportunities. Companies compete to bring Penn Staters onboard for the summer, and many students return to campus with a summer of practical experience and often a job offer waiting in the wings. There are research opportunities, study abroad opportunities, and more to gain experience and academic credit.

Craft your experience.
