Research interests

I am interested in insect-plant interactions, particularly on how insects can cope with defensive metabolites from their host plants. I am currently working with insect sequestration and the specificity of herbivory induced plant volatiles and their ecological consequences.

My expertise areas are:

  • Insect behavior
  • Volatiles
  • Metabolomics


Teaching activities

  • Travaux Pratiques (TP) of Chemical Ecology for bachelor students
  • Integrated Pest Management, Master Biology specialization Sustainable Agriculture
