This week on Gills Talk, Kristen interviews Dr. Lisa Whitenack. Lisa is a biology professor at Allegheny College where she studies the biomechanics, paleobiology, and evolution of sharks, crabs, snails, salamanders, and bony fishes. We learn how a Panera bread baguette lead her to a hypothesis about a shark tooth that is 320 million years old! Lisa's advice is - it's ok to be weird, stick to love what you love, and not bend to peer pressure.
