Christine Bedore (PhD, Aug 2013)

Chris studied the visual and electroreceptive systems of cownose rays that prey upon commercially important bivalves. She integrated comparative morphology with behavioral assays to determine the distribution of receptors and their sensitivity to biologically relevant stimuli including UV wavelengths.

Laura Macesic (PhD, May 2011)

Laura studied locomotion in batoids. She described the pelvic fin musculature, and quantified how various batoid species use their pelvic fins for a novel form of locomotion - punting. This also entailed morphometric and material properties testing of pelvic skeletal elements. Laura is currently an assistant professor in the Biology Department at Wheaton College.

David McGowan (MS, Dec 2007)

Dave studied the effects of salinity on the electroreceptive capabilities of euryhaline elasmobranchs. His experiments determined that stingrays can effectively employ their electrosensory system for prey detection in marine, brackish and freshwater habitats. Dave is currently a PhD student at the University of Washington.

Michelle McComb (PhD, Aug 2009)

Mikki studied the visual system of several elasmobranch species. Using electroretinogram techniques she determined 3D visual fields, spectral sensitivity, and flicker fusion frequency of species that possess a unique head morphology, eye position, and behavioral ecology. She is currently Director of Research and Education at Ocean Classrooms Inc.

Sara McCutcheon (MS, May 2012)

Sara tested the efficacy of lanthanide elements to deter sharks from biting at baited hooks. She measured the electric field generated by various elements and employed behavioral assays to quantify their effectivenes with different shark species. She is currently the education director at Nature's Academy in Bradenton, FL.

Tricia Meredith (PhD, Dec 2011)

Tricia studied the comparative morphology and physiology of the elasmobranch olfactory system. She employed electro-olfactogram recording techniques to determine the sensitivity of sharks and rays to a variety of pure amino acids and biologically relevant odorants.
