RESEARCH INTERESTS

My main research interests lie in the immune and physiological stress responses of fish and shellfish to environmental and anthropogenic perturbations.  As Salmon Disease Lab Manager I am responsible for maintaining the salmon disease research facility, coordinating users, ensuring proper care and use of fish, maintaining healthy fish, monitoring the physical plant, and overseeing the effluent treatment and delivery system.  AQUATIC VIGIL article.

EDUCATION

I received my Bachelor of Science in Environmental Science through Lancaster University, England study abroad program with a year at OSU.   After falling in love with Oregon during my year abroad, I moved to Corvallis and completed my MS in Fisheries & Wildlife at OSU in 2001. The project was studying the effects of endocrine disrupting chemicals on the salmon immune system and involved exposing salmon eggs to DDE for a brief time followed by a subsequent brief exposure of the yolk sac fry to DDE. I then raised the fish to juveniles and tested the fishes’ innate and humoral immune responses, finding that the humoral immune response was affected a year after initial exposure to the chemical.

During my graduate years, I had the opportunity to work in Japan at the National Research Institute of Aquaculture.There I conducted an experiment to determine the effects of water flow on the immune and stress functions of masu salmon. Following graduation I carried out a study to characterize the physiological stress response of lingcod at OSU’s Hatfield Marine Science Center.  From 2001 to 2011 I worked for the Partnership of Interdisciplinary studies for Coastal Oceans (PISCO) at OSU where I worked on several projects. These projects with PISCO included:

1) Ecological studies incorporating biochemical and physiological techniques to evaluate growth and stress indices of intertidal mussels and sea stars in both Oregon and New Zealand.

2) Studies on invertebrate larval distribution and transport along the Oregon and Chilean coasts, where I spent time at the Estación Costera de Investigaciones Marinas (ECIM), located in Las Cruces, central Chile.

3) Investigations into hypoxic zones off the coast of Oregon and Chile working with the Microbial Initiative in Low Oxygen Areas off Concepción and Oregon (MILOCO)

Halfway through my time at PISCO, I was fortunate enough to travel the world for a year, then live in New Zealand for 2 years working at a seafood research institute (Plant and Food Research)  where I conducted research on the physiological responses of New Zealand Greenshell mussels to environmental and harvesting variables.
