Research Scientist (Biostratigrapher)

I am a research scientist at the Geological Survey of Canada – Calgary (Natural Resources Canada), using primarily dinoflagellate cysts and geochemical data as tools to reconstruct past environments and solve geological puzzles.

I was trained as an oceanographer studying living dinoflagellates in the modern coastal ocean, as well as their fossilized cysts in Quaternary sediments. My main research interests are paleoceanography, biostratigraphy, environmental change and phytoplankton ecology, and include elements of biology, marine geology, micropaleontology and environmental science.

Research and/or project statements

Dinoflagellates are a very diverse and abundant group of aquatic protists that occupy a key position in marine and estuarine food webs. Many dinoflagellates produce resting cysts as a dormancy stage, which are well preserved in the sediment over geologic times. Since the distribution of cysts on the seafloor is controlled by the ecology of the dinoflagellates that produce them, cyst assemblages can be used to reconstruct past sea-surface conditions – temperature, salinity, primary productivity and sea-ice cover.

  1. My first major axis of research is dinoflagellate ecology. My aim is to better understand phyto- and microzooplankton dynamics and allow for more detailed paleo-reconstructions. I use primarily sediment trap time series to tie seasonal occurrences of dinoflagellates with physico-chemical and biological parameters.
  2. Secondly, I use cyst assemblages from sediments deposited over the last few thousand years, together with other indicators (such as geochemical proxies), in order to generate detailed reconstructions of past environmental variability at the highest temporal resolution possible. Documenting late Holocene climatic variability is key to understanding the undergoing changes in the environment, whether they are due to natural variability or human activities.
  3. I am now diving into deep time, using dinoflagellate cysts as a tool to reconstruct the depositional history of major sedimentary basins (biostratigraphy) in the Canadian Arctic.

I am also interested into a wide variety of topics, including primary productivity and the different phytoplankton groups that account for it, carbon cycling, coastal and estuarine dynamics, the evolution of life through time as seen in the fossil record, and science education.
