PMI Team

Meet our Researchers

Mitch Doktycz serves as the Laboratory Research Manager of the Plant-Microbes Interfaces Scientific Focus Area (PMI SFA) with Dale Pelletier and Timothy Tschaplinski, who serve as the co-managers. The PMI team includes investigators from the Biosciences Division (BSD) at ORNL. Core collaborators from the University of Washington (Carrie S. Harwood, E. Peter Greenberg, Amy Schaefer), Duke University (Rytas Vilgalys) and the French National Research Institute for Agriculture, Food and the Environment (INRAE-Nancy, France; Claire Veneault-Fourrey) complement the ORNL PMI team. Members of the team are listed below.
