Research

My group focuses on identifying traits to enhance crop resilience towards environmental stressors driven by climate change (e.g., drought, heat, freezing). Our approach leverages concepts from eco-physiology, agronomy, agro-ecology, functional ecology, genetics/breeding and sustainability science. Experimentation relies on 1) various techniques to identify mechanisms enabling plant tolerance to abiotic stressors under various environments (growth chamber to field), 2) a 'translational' component to develop high-throughput phenotyping approaches relevant to breeding and/or predict yield outcomes under current and future scenarios based on the identified traits.
