Science Stuff

I’m currently a research associate with the Dolphin Communication Project (DCP), studying (surprisingly) dolphin communication. I am interested in dolphin social cognition, and have been working with Kathleen Dudzinski and colleagues these past few years studying how dolphins use their pectoral fins to rub each other in various social situations. Yes, it can get awkward.DCPLOGO

The Dolphin Pod

A few years back I hosted the dolphin science podcast titled The Dolphin Pod, produced in conjunction with DCP. You can find an archive of programs at this link on the DCP website. Aside from in depth sciencey-stuff for both kids and the general public (like this episode on the controversy surrounding Paul Manger’s ideas about not-so-smart dolphin brains),The Dolphin Pod also contains funny/educational content, like the Dolphin Species Song, which features my sweet sweet baritone unleashed upon a classic melody inspired by a Gilbert and Sullivan power ballad:
