Dr. Joe Louis

Education

• B.S. in Agriculture, Kerala Agricultural University, 2003
• M.S. in Entomology, Kansas State University, 2006
• Ph.D. in Molecular Biology, University of North Texas, 2011

Professional Responsibilities and Activities

• Research:
  The Molecular Plant-Insect Interactions Lab’s research focus is on identifying the key components/genes/signaling mechanisms that are involved in modulating plant defenses upon insect herbivory and to understand the mechanisms by which insect salivary proteins/effectors alter the plant defense responses.
• Teaching:
  ENTO 409/809, Insect Control by Host Plant Resistance
  ENTO 835, Chemical Ecology of Insect-Plant Interactions
