Dr. Silvere Vialet-Chabrand
TIGR2ESS: Transforming India's Green Revolution by Research and Empowerment for Sustainable Food Supplies Silvere is interested in high throughput phenotyping of traits related to photosynthesis and stomatal conductance under a dynamic environment. He has developed tools to identify cultivars with improved photosynthetic performance, which is key to improve yield and global food security in the future. Outcomes from these works have attracted the interest of agritech companies and will improve our understandings of leaf gas exchange and energy balance under fluctuating light conditions. Research is funded by the TIGR2ESS project to support cutting-edge research and innovation addressing key challenges in global food security. Previous projects: Wider and faster: high-throughout phenotypic exploration of novel genetic variation for breeding high biomass and yield in wheat
