Menu Downeast Institute

On 1 March 2012, DEI welcomed Dr. Phil Yund as its first Senior Scientist.

DEI's Board of Directors is excited about Dr. Yund's research in marine ecology and fisheries ecology as his work will enable our organization to strengthen its ties with the scientific community as well as fishing communities in the Gulf of Maine. 


Dr. Yund studies the evolutionary ecology of sessile and sedentary marine invertebrates as well as fertilization ecology, ecology of marine mammals, fish, and invertebrate pathogens. 

Currently, he is conducting research in a variety of areas:

  • the hydrodynamics and fertilization in green sea urchins, Strongylocentrotus droebachiensis;
  • processes determining range boundaries and population connectivity in blue mussels, Mytilus edulis, and M. trossulus;
  • dynamics of the discharge plume from the Saco River; and,
  • host affinity of Giardia and Cryptosporidium  genotypes.
