Research interests

My research activities are motivated by questions regarding the impact of natural environmental and anthropogenic changes on aquatic systems. I use microfossils (primarily dinoflagellate cysts, and diatoms) and geochemical tracers preserved in sediments to reconstruct changes in climatic, environmental and oceanographic conditions on time scales spanning from decades to millennia. I have a special interest in proxy development and intercomparison.

Selected research topics of interest:

  • Interactions between climate, sea ice and primary production
  • Response of marine protists to environmental changes
  • Harmful algal blooms, from the tropics to the high latitudes
  • Human settlement and migration in relation with climate fluctuations

Current students

  • Liam MacNeil, Bsc Honour's, Department of Biology
  • Kelsey A. Koerner, MSc candidate, Department of Earth Sciences
  • Joshua R. Evans, PhD candidate (co-supervised with Dr. Gary Saunders), Department of Biology

The PAst Primary production and Environmental Reconstructions (PaPER) laboratory is committed to provide a diverse, inclusive and supportive research and working environment. We welcome all qualified students and professionals, and encourage women, Inuit, First Nations, members of visible or cultural minorities, LGBTQ and all who may contribute to further diversification of research approaches, ideas and group dynamics.
