Science Serving Maryland's Coasts

REU Mentor Profile
Judy O'Neil, Ph.D.

Location:

Horn Point Laboratory

Research Topics:

Coastal and Estuarine Processes

Research Interests:

I work on cyanobacteria ecophysiology and plankton trophodynamics. Current projects include studying the nutrient dynamics of the red-tide dinoflagellate, Karenia brevis in the Eastern Gulf of Mexico Florida and examining land use and nitrogen cycling in Coastal Bays, Mayrland. I have studied the ecology of toxic marine cyanobacteria Lyngbya spp. in Florida estuarine and coastal waters.
