Glenn John Dunshea

About

I have a broad background in molecular ecology, marine ecology and the intersection of these two disciplines. My main research interests encompass understanding the distribution, abundance and population ecology of marine species and the ecology of the communities they inhabit. I work in a wide variety of ecosystems from polar benthic ecosystems to tropical coral reefs. My emphasis is predominantly on the current state and future fate of coastal communities and species, focusing on how human impacts, evolutionary history and interactions/structuring within and between species influence this. I try to combine state-of-the-art experimental design, laboratory and statistical approaches.

I am also interested in developing and applying new molecular techniques for otherwise intractable ecological and evolutionary questions, regardless of the biome. In my role at NTNU I support several environmental DNA, metabarcoding and biotechnology projects and am actively developing a related research program.

I am always seeking students interested in molecular ecology and/or coastal marine ecology and conservation, so I encourage students to contact me if they are interested in these areas.
