Research Interests

Double-tagged weakfish

Double-tagged weakfish

My primary research interests are focused on addressing aquatic ecological questions that can be applied to fisheries and resource management. I am specifically interested in fish trophic interactions, growth and recruitment, movement patterns, mortality, and their use as biological health indicators. I use multiple approaches in my research, ranging from simulations and hierarchical modeling to hands on field work in the form of telemetry and fish tagging.

My research involves collaboration with state and federal agencies, fellow academic researchers, along with commercial and recreational fisherman. Previous research projects have focused on coral reef monitoring, lake management plans aimed at controlling invasive aquatic plants, and power plant compliance to the EPA’s 316(b) mandate.

For my masters I developed a stream indices of biotic integrity in South Dakota and researched the age structure, growth, and diet of northern pike in prairie streams. My current dissertational research focuses on better understanding the decline of weakfish (Cynoscion regalis) in North Carolina’s coastal waters by estimating fishing mortality through the use of high reward conventional tags and natural mortality through telemetry. Please visit the Weakfish Tagging Study page or my dissertation for additional project information.

My current postdoctoral research estimates cobia (Rachycentron canadum) survival using telemetry.
