Research Interests

My laboratory has two foci. We have a long-term interest in the basic molecular, cellular, and immunochemical aspects of teleost immune system function. This knowledge is also applied to the understanding of disease resistance and pathogenesis, as well as the development of immunodiagnostics and vaccines for aquaculture. A more recent focus in the development of monoclonal antibody probes for incorporation into real-time sensor platforms to monitor the presence and flux of pollutants, toxins, and pathogens within the estuarine environment.

Projects

• The differentiation of long-lived plasma cells and plasmablasts and their role in generating humoral and classical memory and disease resistance in fish
• Structure and assembly of fish antibody molecules
• Mechanisms of affinity maturation and antigen-driven selection in fish
• Development of real-time, antibody-based sensor platforms for the detection of pollutants and pathogens in estuarine water
