Research Interests
- Top-down ecosystem effects in the marine environment
- Physiology and sensory systems of fish (esp. Elasmobranchs)
- Habitat use and movements of stingrays and stingarees in response to varying environmental factors
- Field energetics and biomechanics of rays
Current Projects
Formerly, my primary area of interest focussed on stingray sensory systems- specifically the electroreceptive ampullae of Lorenzini and the mechanoreceptive lateral line. This research drove my fascination with rays further after presenting at Sharks International (2010) in Cairns, where I realized only a select few in the elasmobranch world concentrate on stingrays.
Currently I am investigating the elusive ecology of stingrays and stingarees found within estuaries of New South Wales. Contrary to what you have been told, rays are harder to catch than you think- at least the decent sized ones! If you are inclined to disagree, then I challenge you to demonstrate your awe-inspiring angling ability. A large part of my research involves implanting acoustic transmitters in rays, from Georges River, Shoalhaven River and Clyde River, to track their long-term movements, habitat use and activity patterns in response to a suite of environmental factors including temperature, salinity, bathymetry and diel cycles.
Further, I am validating the use of stingray barbs as a potential tool to determine stock structure and residency within and among species. Topping it off, I am also investigating stingray biomechanics and respirometry to be applied to free-living stingarees in the Shoalhaven River using novel accelerometry tags. In conclusion- stingrays are as awesome as the people who study them (this inc. my supervisors).
