Research Scientist

I am a botanist with a background in systematics, ecology, and conservation biology. My research at AAFC focuses on the diversity of uncultivated plants in agricultural ecosystems, including crop wild relatives, weeds and invasive species.

Current research and/or projects

Modeling IAS risk under climate change 2019-2021

Assessing the range potential of Invasive Alien Species (Dog-strangling Vine) and associated herbivores under climate change with geospatial models of biological collections data

 

Supporting Makkovimiut food systems 2021-2025

Identifying key factors contributing to yield variability, assess pollinator communities, and develop locally-relevant semi-cultivated management practices for Rubus chamaemorus (bakeapple) to enhance annual yields.

 

Systematics of Weeds, Crops, and Crop Wild Relatives 2019-2025

Assessing in situ diversity of important berry crop wild relatives (Vaccinium, Rubus).

Research and/or project statements

My work focuses on the diversity of uncultivated plants in agricultural systems. This includes assessing the current and potential risks posed by weeds and invasive species, and evaluating the genetic and taxonomic diversity of crop wild relatives with the potential to enhance the sustainability and resilience of Canada's agricultural sector.
