My research interests lie at the intersection of historical climate variability and future climate change. I am interested in the calibration and application of a variety of tools that allow (paleo)oceanographers to reconstruct the ocean environment through time in order to contextualize and improve our understanding of future change. Broadly, I am interested in ocean change, climate variability, biogeochemistry of the environment, carbon cycling and investigating ways to mitigate anthropogenic impact on the climate.

My MSc in Oceanography work (Dalhousie University - Kienast Lab) involved the investigation and calibration of a novel paleo-salinity proxy for reconstructing surface ocean salinity throughout earth’s history. The proxy was developed using stable hydrogen isotopic compositions (delta-deuterium) of a biomarker molecule called an alkenone, which is produced exclusively by marine prymnesiophyceae (calcareous green algae termed coccolithophores). You can read all about this novel calibration model here.

My PhD work focused on investigating calcium carbonate proxies in long-lived crustose coralline algae for reconstructing ocean dynamics over the last millennium in the Northwest Atlantic and Canadian Arctic Oceans.

My current Postdoctoral Research in the Stubbins Lab @ NU involves some exciting new work on carbon dynamics in macroalgae - both in the context of 'natural' carbon cycling and marine carbon dioxide removal (mCDR).
