Environmental Biology

Explore the science of life from minute strands of DNA to complex ecosystems that stretch for miles and miles.

Our program offers opportunities for research and study using the latest technology and equipment, in the lab or in the field.  In faraway tropical rainforests and coral reef habitats or New Hampshire’s own lakes and forests, PSU students work hands-on with faculty members to answer some of life’s toughest questions.

As an environmental biology major you’ll experience:

  • Degree programs in biologycell and molecular biology or environmental biology
  • Minors in biology and neuroscience
  • Courses in zoology, anatomy and physiology, conservation, ecology, biochemistry, microbiology, genetics, and marine biology just to name a few
  • Opportunities for local, national, and international field studies
  • talented and diverse faculty
  • State-of-the-art laboratory and research facilities, including an electron microscopy suite, 1,400-liter marine aquarium, fully equipped human physiology lab, museum and specimen room, and rooftop greenhouse
  • Partnerships with the Center for the Environment, an innovative regional research center focused on environmental science and conservation.
  • We also have graduate programs available.
