Research Interests:

  • seabird ecology
  • marine conservation
  • seabird population delineation
  • marine foodwebs
  • GIS and telemetry applications

Bio: I am a postdoctoral research associate working on the global bycatch assessment of seabirds, marine mammals and sea turtles (aka Project GLoBAL). My research centers on fisheries bycatch effects on birds. I am particularly interested in employing seabird telemetry data to improve our understanding about bycatch. In the past, I participated in studies of shellfish aquaculture effects on sea ducks in British Columbia and I also studied waterbird habitat use, trophic ecology and bird-fisheries interactions in the Baltic Sea.
