He’s voiced characters in animated films (including playing the titular Thor in Thor: Legends of Valhalla), produced radio plays, and released three albums with the ECMA and Music Nova Scotia award-nominated children's group Bingly and the Rogues. He also fronts a Nova Scotia-based post-punk-dad-band called Minivans.

His talks explore the shortcomings of human thinking, the brilliance of animal minds, and the power of creativity and comedy. Justin’s unusual background—dolphin researcher, improv performer, musician, science communicator—means he bring something different to every keynote, workshop, and event. He uses humor, storytelling, and unexpected comparisons to animal cognition to make complex scientific ideas feel both accessible and fun.
