About Me

I am currently a doctoral student at the University of Connecticut, working under the care and guidance of Dr. Eric Schultz.

My research interests are broad, but my work centers around the physiological, molecular and evolutionary ecology of fishes

I'm also on Facebook

Dissertation Research

My dissertation research focuses on answering questions regarding the osmoregulatory system in bony fishes, that is, the set of physiological mechanisms by which water and ion homoestasis is maintained. Specifically, I am investigating both the micro-evolution and the ontogeny of the osmoregulatory system in an anadromous shad known as the alewife (Alosa pseudoharengus)

The reason I have chosen to study alewives is because of their interesting life history. Most alewives are anadromous - adults inhabit the open ocean and return yearly to small, freshwater systems to spawn. In addition, multiple populations of alewives have been independently restricted to freshwater systems year-round - a phenomenon known as land-locking. Land-locking in alewives provides a unique opportunity to investigate the specific physiological and molecular adaptations made by fish when they transition from living in seawater to specializing in freshwater - environments that require drastically different methods of osmoregulating. Not only does this represent a significant gap in our knowledge of osmoregulatory physiology, but changes to this system that permitted organisms to specialize in FW represent major evolutionary transitions

My research focuses mainly on the osmoregulatory processes of the gills, since gills are the main site of ion exchange in fish. My endpoints of interest include survival, plasma osmolality, ion transporter activity, gene expression and transcriptome modifications after prolonged periods of salinity challenge
