My main interest is the study of population’s ecology. During my doctoral research, I investigated low-density population dynamics. My work was focused on Spanish Imperial eagle and Osprey reintroduced populations in South Spain. I was interested in the response of growing populations (in particular reintroduced populations) to low density situations that include behavioral response, breeding biology and movement ecology.  In addition, I am involved in a project with black-browed albatrosses in the Falkland Islands, studying winter and foraging movements related with nutritional conditions and climate change.  During my postdoctoral research at Oregon State University, I am investigating population dynamics of penguins related with climate changes.
