I am a behavioral ecologist with a background and interest in foraging behavior and migration. I am interested in the mechanisms by which organisms deal with the aspects of their (changing) environment and I am fascinated how animals respond to this. Are animals phenotypically flexible or do they change their distribution and diet? These are key questions that I aim to unravel by integrating behavior, demography and population dynamics using statistical and theoretical models with empirical data.
Currently I am working on the distribution and migration patterns of several shorebird species in North America using the motus wildlife tracking system. In addition to this, my work will expand on marine-shipping wildlife interactions in the Canadian Arctic.
