Marine Scientist

Andre works on prey-predator relationships and interactions with their environment using little penguins as an ecological model. Together with collaborators, they have been using more sensitive variables such as foraging efficiency, presence/absence of thermoclines, foraging-trip-duration, isotopic niche analysis, fractal diving analysis and new spatial-temporal scales to detect penguins' response to environmental changes. His research produced over 100 scientific papers in peer-reviewed journals, mainly on little penguins at sea. Andre is on the editorial board of PLoS ONE and section editor of PLos Climate, past editor of the Australasian Seabird Group Bulletin, current a steering committee member of the  IUCN Penguin Specialist Group and adjunct Associate Professor to the Monash University.
