Judith Grassle (born on December 4, 1936[1]) is a Professor Emeritus in the Department of Marine and Coastal Sciences at Rutgers University.
Grassle is a benthic ecologist known for research on invertebrates, especially polychaete worms including the now-named Capitella teleta.
[1] Following postdoctoral work funded by the Office of Naval Research at the University of Queensland, Grassle joined the Marine Biological Laboratory (MBL) in Woods Hole, Massachusetts, first as an independent investigator in 1972, and then served as a Senior Scientist from 1986 to 1989.
[11] Judy Grassle has widely shared cultures of Capitella teleta[12] thereby enabling other scientists to conduct work on this polychaete worm.
[18][19] Subsequent work by Grassle expanded the description of the sibling species of Capitella based on chromosomal differences determined by karyotyping.
