Current Courses

  • PLSC 467/667 Paradigms in Cell Signaling
  • PLSC675 Current Topics of Plant Biology


  • Our major research focuses are on elucidating how pant cells communicate through plasmodesmata, plant-unique intercellular communication channels by identifying the molecular components and investigating their roles in plant growth and development.

Professional Activities

  • American Society for Biochemistry and Molecular Biology (since 2005)
  • American Society of Plant Biologists (since 1994)
