Profile

My interests in marine biology began in grade school when I started fishing for bluefin tuna with my father in the Gulf of Maine. Those days on the water made an indelible impression on me, eventually inspiring me as an undergraduate to study biology. After graduating from Cornell with degrees in Biology and Science Education, I taught high school science for two years and worked as a technician at the Shoals Marine Laboratory in Maine. My experience at Shoals convinced me to make a career of marine biology and enrol at the University of Guelph, where I worked on the physiology of bluefin tuna. After receiving my MSc from Guelph, I worked on a variety of tuna tagging projects with Barbara Block at the Monterey Bay Aquarium. I did my PhD with John Gosline at the University of British Columbia, where I specialized in comparative animal biomechanics. My dissertation on hagfish slime led to some unexpected insights into the mechanical design of animal cells, which I pursued as an NSERC postdoctoral fellow in Wayne Vogl's lab in the Dept. of Anatomy and Cell Biology at the University of British Columbia. Research in my lab focuses on the comparative physiology and biomechanics of hagfishes. We also work on a group of fibrous proteins known as intermediate filaments. See below for more information on current research projects.
