Her dissertation research covers the ecology and genetics of Caenestheriella gynecia Mattox 1950, a poorly understood species of the clam shrimp family Cyzicidae, from three localities: New Jersey, Massachusetts and New York. Currently, she is an adjunct Assistant Professor at Hofstra University, CUNY Queens College and Medgar Evers.
She developed an aquatic ecosystems course for a College Now Authentic Research Module for 10th and 11th grade high school students. For the 2008 - 2009 school year, Flushing High School hosted her as a GK-12 Fellow. Townsend Harris H.S. was her host during the 2009 - 2010 school year, where she developed curriculum on how to perform background research for scientific projects. She has pilot tested her course, Puddle Smuddle, in Spring 2011 at Queens College with a high retention of students and performance. It is now being considered to be part of the science College Now series at Medgar Evers, where it is currently being taught.
