Happy Feast of St. Francis of Assisi, the patron saint of ecology! He was my favorite saint as a kid because he could speak to animals (duh, how could he not be your favorite in that case).

Check out this lovely profile of the University of California, Davis’s Peter Wainwright, whose lifelong fascination with fishes inspired a remarkable career in research and teaching. Peter was my postdoc advisor years ago when he was at Florida State University, and is awesome dude and mentor.

Among the Academies: A Lifelong Fascination With Fish
For Peter Wainwright, the academic path was simple: he simply followed his fascination with fish.“I dare say there wasn't a lot of deep thought about what direction I should go in my life,” he said. “...
