Front and center in Aaron Wirsing’s office is a framed and colorful drawing of killer whales chasing down dinner—seals, fish, dolphins, other frightened sea creatures.  The artist?  A 10-year-old Aaron, inspired by the nature television shows of his youth.  “Predators always fascinated me.  Nothing’s changed!,” said Wirsing. Now an assistant professor in the School of Environmental and Forest Sciences, he still pursues his passion for predators.
