PROFESSIONAL BACKGROUNDSince 1997 I have been applying statistical techniques to address questions of interest for a wide range of animal species including seabirds, grizzly bears, sea lions, frogs, salamanders, owls, ducks and giant weta. I have acted as a statistical consultant to a number of national and international institutions including the Department of Conservation, Ministry of Fisheries and the U.S. Geological Survey.
