Research Interests

My present research focuses on oyster stock assessment and evaluation of oyster restoration efforts in Delaware Bay, and on deep sea and estuarine taphonomy.    I am also interested in oyster disease research, and have developed and validated methods for the use of flow cytometry to investigate the morphology and function of bivalve hemocytes.

 

Current Research Projects

• Oyster Stock Assessment and associated Programs in Delaware Bay (NJ)- State of New Jersey
