Research Interests

I am interested in investigating the trophic and spatial ecology of marine top predators. I have been applying natural chemical tracers to learn about the foraging ecology and habitat use by marine mammals, how sympatric cetacean species compete for available resources, and how human-induced changes can affect the structure and dynamics of marine pelagic ecosystems.

Biography

As I grew up in a coastal city in southern Brazil, the sea, the marine ecosystems and particularly, marine mammals, have always fascinated me. When I was about 12 years old I had the opportunity to participate in a workshop in the oceanographic museum in Rio Grande (my home town), where I had the change to learn about the coastal and marine ecosystems of southern Brazil, their amazing marine life, and the challenges that they were facing as a result of human actions. I think that this is what drove me to pursue a career in marine sciences. I have been particularly interested in learning about the trophic ecology of the marine megafauna, how their feeding behaviour affects their spatial distribution and how environmental changes will affect their survival.
