Areas of Expertise:

  • genetics and enhancement of perennial forage legumes and grasses
  • identification of selection criteria and new technologies leading to the development of new cultivars and experimental populations
  • selection for tolerance to biotic and abiotic stresses and for characters related to the requirements of the forage and bioenergy industries

Current Projects:

  • Development of new cultivars of alfalfa with increased productivity, adaptability and persistence through selection for tolerance to biotic and abiotic stresses
  • Development of new cultivars of timothy with an improved nutritional quality through selection for increased fibre digestibility
  • Evaluation of an approach based on recurrent selection to identify molecular markers associated with tolerance to biotic and abiotic factors in alfalfa
  • Development and evaluation of germplasm of switchgrass and reed canary grass for environmental adaptation, biomass potential and conversion into bioenergy
  • Participation in regional trials on forage crops and biomass
