Research Interests:

The polar marine environment is experiencing intense climate change, including physical, chemical and ecological changes, many of which directly feedback to the global climate system. While polar oceans act as a sink for anthropogenic CO2, their capacity to absorb atmospheric CO2 is expected to change as a consequence of climate change. My main interest lies in the marine carbon cycle of the polar oceans, in the context of global carbon sequestration. The overarching objective of my research is to understand and quantify the implications of climate changes on carbon biogeochemistry in the polar marine system. More specifically, I am interested in the role of sea ice in term of carbon cycling across the ocean-sea ice-interface and I am also interested to examine how changing sea ice regimes will impact carbon biogeochemistry.
The amount of plastic litter in both marine and freshwater environments has increased drastically, becoming a major concern. Arctic sea ice has been reported to contain microplastic concentration of magnitude higher than in surface seawater. I am interested to study the interactions of those particles with sea ice and how they could affect the ice-light interactions, growth and melt of sea ice, photochemical and biological processes in marine cryosphere.  Having the opportunity to study under the guidance of Dr. Soren Rysgaard, both at the University of Manitoba (2011-2013), and at the Arctic Research Centre at Aarhus University (2013-2015) has expanded my knowledge in my research interests greatly.
