Welcome to my website. I am a biologist interested in investigating the trophic and spatial ecology of marine top predators. I have been applying natural chemical tracers to learn about marine mammals foraging ecology and habitat use, competition for resources by sympatric species, and how human-induced changes can affect the structure and dynamics of marine pelagic food webs. 


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). During this workshop I learned about the coastal marine ecosystems in southern Brazil, and the challenges that marine species 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. In addition to doing science, reading non-fiction and thriller books, spending time outdoors hiking or biking, and Body Pump are amongst my favourite things to do.
