In the broadest sense my research interests and experiences are in the area of Fish Ecology, emphasizing the impacts of environmental conditions on the expression of behavior.  It should be noted that at the intersection of environment and behavior are physiological responses.  As such, much of my research has focused on the integration of behavior and physiology as it relates to environmental experiences.  Recently, my research direction has expanded to incorporate impacts of various components of the ecosystems (prey presence, interspecific interactions, and water chemistry) on fish behavior and population dynamics.  I have found that results from these research topics are useful for natural resource managers making decisions associated with environmental impacts on natural (or artificially-enhanced) populations of fishes.

Research interests

Current projects include:

  • Presence and distribution of Atlantic and shortnose sturgeon in the Penobscot River and Gulf of Maine.
  • Application of modern acoustic technology and spatial analyses to estimate densities of aggregating sturgeon.
  • Assessing the impacts of tidal turbines on fishes using acoustic techniques.
  • Documenting spawning of shortnose sturgeon in the Penobscot River.
  • Hydroacoustic documentation of diadromous fish migrating in the lower Penobscot River.
