Catastrophic consequences of ship collisions on marine life
All too often, ships collide with marine animals out at sea. Learn more about these collisions and how they occur.

I received my PhD in Biology from Wake Forest University, and I received a BS in Biology from Cornell University. My research focuses on the terrestrial locomotion of fishes. I am particularly interested in how different fishes move differently on land, and how one fish may move differently in different environments. While I tend to study small amphibious fishes, I've had a lifelong fascination with all ocean animals, and sharks in particular. When not doing science, I enjoy running, attempting to bake and cook, and reading.
