Dr. Phil YundSenior Scientist

Call Phil Directly

DEI welcomed Dr. Phil Yund as its first Senior Scientist on March 1, 2012. Dr. Yund focuses on marine and fisheries ecology.

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.

Dr Yund is conducting research in a variety of areas:

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