Focus

Research

Plants exhibit incredible adaptability to their external environment via an intricate cohort of signaling mechanisms that simultaneously regulate growth and disease physiology. The long-term goals of my program are to understand these intricate signaling mechanisms. For this, we primarily use Arabidopsis and soybean as our experimental systems to study local and systemic defense responses against viral, bacterial, and fungal pathogens. On-going projects are focused on: 

  • Understanding the movement of chemical signals that regulate plant systemic immunity
  • Understanding how glycerolipid metabolism interfaces with defense signaling
  • Identifying and characterizing plant targets of microbial effectors
  • Understanding the overlap in responses induced by pathogenic versus beneficial microorganisms
