Gregg is Senior Research Associate and Vice President of the Dolphin Communication Project, a non-profit research organization focused on the study of dolphin behavior and communication. He is also an Adjunct Professor with the Biology Department at St. Francis Xavier University. In his career as a research scientist, Gregg has published dozens of peer-reviewed articles, book chapters, and presented at scientific conferences across the globe. He was the lead researcher in charge of video and audio data collection for the 2005 – 2007 research seasons in Mikura Island Japan as part of his PhD research. Gregg has served on the editorial board of the journal Animal Behavior and Cognition since 2013, and is currently President of Aquatic Mammals Journal, for which he was the co-editor from 2009-2014.
