Since 1985 a large proportion of the research I have undertaken has focused on killer whales. My Ph.D. research through Simon Fraser University, completed in 1994, focused on the foraging behavior and ecology of the mammal-eating transient killer whales, but I have also studied the behavior of fish-eating residents in Washington, British Columbia and Alaska, as well as the behavior of killer whales in Iceland, and some work with killer whales in Mexico and Hawaii. A list of publications and reports on this research (including pdf files) is below.

Current projects focus on the diving behavior of mammal-eating killer whales, movement patterns of mammal-eating killer whales, and a study of diet and behavioral cues of predation in fish-eating killer whales. This latter project was begun in 2002 in collaboration with Dr. Brad Hanson of the Northwest Fisheries Science Center and involves collecting fecal samples (for genetic analysis of diet) and prey remains left behind foraging whales. As part of the effort to examine diet and underwater behavior, with Greg Marshall and Dr. Mike Heithaus of the National Geographic Television Remote Imaging Program we deployed one Crittercam on a fish-eating "southern resident" killer whale (K25) in 2002, obtaining the first underwater video footage collected from a killer whale. Unfortunately the whale was not foraging while the camera was attached, but the video footage obtained (see above) does demonstrate that this technique should be useful to examine underwater feeding.
