I am an Adjunct Professor of Environmental Studies and Sciences at Adelphi University and PhD candidate in Marine Science at Stony Brook University that is broadly interested in the climate and human drivers of biogeochemical and ecological change in coastal ecosystems.

My dissertation research involves characterizing the spatiotemporal variability of coastal hypoxia, acidification and warming, and assessing the effects on economically important shellfish. I like to collect high frequency observations of environmental parameters such as temperature, dissolved oxygen, and measures of the carbonate system to pair with experimental in-situ and laboratory approaches with shellfish.

  • Evaluating the sensitivities of Atlantic bay scallops to environmentally relevant frequency and magnitude domains of hypoxia & warming

  • Quantifying the spatiotemporal variability of summer hypoxia/acidification across New York estuaries

  • Determining the vertical and horizontal extent of summer acidification and hypoxia in Atlantic sea scallop habitat of the New York Bight

  • Assessing effects of hypoxia and acidification on the survival, development, and physiology of blue crab larvae

  • Characterizing the baseline variability and associated drivers of the carbonate system and dissolved oxygen conditions of oyster reefs

  • Identifying the quantitative contribution of sedimentary nutrient fluxes to nitrogen loading and harmful algal blooms in NY estuaries


  • Assessing the effects of day-time oxygen supersaturation and pH basification on diel-cycling hypoxia- and acidification-stress

  • Determining the influence of seasonally warming temperatures on the occurrence of hypoxia in shallow semi-enclosed embayments


  • Establishing hard clam spawner sanctuaries to improve filtration capacity and facilitate the hard clam recovery in Shinnecock Bay, NY

  • Initiating the build-out and monitoring of restored oyster reefs in Shinnecock Bay, NY
