Research interests:

  • Environmental contaminants
  • Aquatic food web structure and function
  • Land-ocean interactions
  • Plankton ecology
  • Catchment biogeochemistry.

I am an aquatic ecologist interested in taking integrative and interdisciplinary approaches in order to gain an understanding of the complex and diverse stressors that currently face freshwater and coastal environments.

Selected national and international projects:

  • TerrACE: Effects of terrestrial inputs on Arctic coastal ecosystems (2017-2021)
  • Climer: Drivers of mercury in freshwater fish in northern lake ecosystems (2015-2018)
  • COCO: Effects of climate change on coastal contaminants (2014-2017)
  • DOMCON: Effects of riverine inputs on lower food web structure and Hg bioaccumulation in fjords (2015-2016)
