Teaches Environmental and Marine Sciences courses including Marine Ecology, the Environmental Seminar, Ecology and the Environmental Challenge, Oceanography, and Fisheries.

Scholarly interests - harmful algal blooms, toxins in marine food webs, effects of changing environments on plankton productivity.

Greg Teegarden's research is in the field of harmful algal bloom (HAB) ecology, focusing on bloom dynamics and trophic interactions of Maine's "red tide" alga, Alexandrium. His early work focused on planktonic food webs, and toxin transfer from plankton to higher levels. More recently, he focuses on oceanographic effects of changing climate and hydrography on coastal harmful algae populations.

Outside of work, Professor Teegarden enjoys outdoor activities such as hiking, skiing, and kayaking, music and instrument construction, antiquarian books, but most of all, family.

Pedogogical Methods

He enjoys promoting project-based learning, and community-engaged learning. He is an instructor on the experiential/immersion Environmental Science Semester.

Excursions/Trips with Students or for Academic Research

The Environmental Science Semester takes 8-10 students into the field for a 10 week immersion into environmental and marine science. All students learn by doing, studying diverse ecosystems from the mountains of New Hampshire to the salt marshes of southern Maine, through Atlantic Canada, along the coast and even on a sailing schooner in the Gulf of Maine. Research with interns keeps us busy in the waters of Casco Bay.
