Current research and/or projects

Crop species face numerous types of abiotic and biotic pressures, which often severely limit productivity and are predicted to become even more problematic in coming years due to climate change. In addition, inadequacies in forage quality can lead to substantial economic losses for producers and the emission of significant quantities of greenhouse gases. As such, there is a very diverse range of traits that could be enhanced to improve sector profitability, sustainability and competitiveness, and also reduce environmental impact. To address these challenges, my research program focuses on unraveling the genetic mechanisms driving various performance- and quality-related traits, especially in forage crops, as well as the improvement of these traits using advanced molecular breeding tools such as genome editing.


Research and/or project statements

  • developing genome editing technology in forage crop species to increase the pace and precision of breeding
  • improving abiotic stress tolerance to increase climate change resiliency
  • enhancing photosynthetic efficiency/capacity to increase productivity
  • boosting oil production in vegetative tissues to reduce methane emissions from livestock production
