Biologically-Based innovations driven by novel insights of plant and microbial metabolic strategies for advancing climate resilient agriculture and food systems in the United States and globally.
Specific innovations and technology platforms focus on,
1) plant abiotic stress tolerance for climate resilience;
2) human health relevant nutritional qualities, and
3) post-harvest preservation qualities of food plants and plant-based foods for countering food wastes.
Fundamental research focus is on understanding critical metabolic pathway regulation related to biosynthesis of secondary metabolites (phenolics) and advancing natural elicitor-based (chemical and microbial) strategies to improve phenolic bioactive content in food plants for above multiple solutions. This novel approach harness dual function benefits of plant phenolics for sustainable food and nutritional security solutions and for addressing climate change-linked agricultural production challenges.
