Field Crop Entomologist

I am involved in insect pest monitoring, integrated pest management, biodiversity surveying, and development of novel tools for insect biocontrol. I have a background in insect physiology, particularly in relation to cold tolerance and diapause (overwintering).

Current research and/or projects

I aim to improve insect surveying methods, understand how agricultural practices influence native insect biodiversity, develop new biocontrol tools that protect both the environment and Canadian agriculture, and ensure that Canada is prepared for new and anticipated insect pests.

I have a background in insect overwintering physiology and cryobiology, which I hope to apply at AAFC. Prior to joining AAFC, I studied mechanisms of extreme freeze tolerance in malt flies at the Biology Centre CAS (Czech Republic), after which I studied circadian clock outputs in bean bugs at Osaka City University (Japan). 

Research and/or project statements

  • Biomonitoring of orchard pests and Japanese beetles in Southwestern Ontario
  • Developing molecular tools to identify cecidomyiid midge pest presence in cruciferous field crops
  • Surveying and assessing native insect biocontrol agents for tomato pests
  • Surveying beneficial insects in various organic field crop systems
