The Lab

  • Nick Ray

    Dr. Nicholas Ray

    Nick is an Assistant Professor and oversees the research group. His research interests center on the biogeochemistry and ecology of aquatic ecosystems and how these ecosystems respond to change. Nick earned his Ph.D. in Biology at Boston University and B.Sc. and M.Sc. in Environmental Science and Technology at the University of Maryland. Prior to joining the School of Marine Science & Policy at the University of Delaware, he was a postdoc at Cornell University and Stockholm University.

  • Sophia Glastein

    Sophie is a first year M.S student in the lab. She recently graduated with a B.A. in Marine Science with a minor in Chemistry from Boston University. During her undergraduate studies, she completed a series of investigations comparing oyster morphometrics to nutrient cycling, specifically nitrogen. Sophie plans to continue researching drivers of oyster mediated biogeochemistry with the Ray lab. She is also pursuing a professional dance career!

  • Sarah Hemminger

    Sarah is a junior marine science student with a concentration in biology and a minor in Spanish. She has previously studied oyster recruitment responses to environmental characteristics in the Lewes-Rehoboth Canal and how Red Mangroves in southern Florida are responding to rising temperatures. Outside of science, she also really loves to pursue art and thoroughly enjoys oil painting and drawing.

  • Jocelyn Holloway

    Jocelyn is a junior marine science major with a concentration in biology and interests in conservation and sustainability, as well as crustaceans.

  • Gabby Walker

    Gabby is a Junior undergraduate student studying Marine Biology. She is working with Dr. Ray and Sophia to learn more about data collection, gas cycling, and nutrient cycling in a nearby marsh. She also plans to join the US Space Force!
