PhD in Biological Sciences from the University of Buenos Aires. He currently works as Principal Researcher at CONICET and Professor at the National University of Tierra del Fuego, Antarctica and the South Atlantic Islands. For 30 years he has been studying the ecology of birds and mammals in Tierra del Fuego, generating applied knowledge to resolve conflicts with human activities and the creation of protected areas. In the last 15 years his career has focused on studies applied to invasive species in Tierra del Fuego, such as beavers and feral dogs.

He has participated in more than thirty research, conservation and environmental education projects in various natural areas of the country covering several different environments and species. These experiences involved working together with local leaders, local authorities, researchers, park rangers, environmental educators, members of NGOs, and local communities. His academic work is mainly focused on the ecology of communities and the trophic ecology of Patagonian birds, studying for more than twenty years the structure of bird assemblages associated with marine and continental wetlands as well as those associated with terrestrial environments in Patagonia and diverse aspects of the trophic ecology of seabirds.

Phd. Andrea Raya Rey - Seabirds in Tierra del Fuego  
Biologist and PhD in Marine Ecology, of the University of Buenos Aires, Argentina. Andrea lives and works as a researcher at CADIC- Argentine National Research Council.  She has been studying seabird ecology and conservation, during the last 20 years mainly in Tierra del Fuego, Beagle Channel and Staten Island, but also in other places in Patagonia, Antarctic Peninsula and the extended Patagonian Shelf. Her research has been funded by national and international agencies, including Wildlife Conservation Society as a field staff. Andrea has been carrying on a long-term monitoring on breeding, feeding and spatial ecology of seabirds in the region.
