Bio
I am interested in how animal size affects physiology and, conversely, how physiology constrains animal size. Right now, I’m focusing on how the sensorimotor system changes with animal size, and how this affects the ways that large and small animals sense and respond to their environment. I’ve looked at the nerve conduction velocities of animals ranging in size from tiny five gram shrews to 3,800 kilogram elephants, and am currently investigating how other neuromuscular delays are different (or not!) in these animals. I’m also looking at how the number of nerve fibers in peripheral nerves changes with animal size, and have worked with researchers from the Medical Image Analysis Lab at SFU to develop software which identifies axons and myelin in nerve images. Another exciting collaboration was with the Danish Cardiovascular Giraffe Research Project, during which I travelled to South Africa to study neuromuscular delays and nerve fiber number in giraffes, and to learn about how the unique shape of this animal affects its neural control.

When I’m not in the lab, I enjoy getting outside and kayaking, biking, or rock climbing. I also love going on epic backpacking trips to Europe, India, and Africa. At home, I can often be found baking delicious food and knitting geeky socks.
