Meet The Team

The PPDL could not provide the range of services we offer without the diagnostic expertise provided by specialists in other departments. As in past years, faculty and staff from the Departments of Botany & Plant Pathology, Agronomy, Entomology, Horticulture & Landscape Architecture, and Forestry & Natural Resources very generously assisted with providing problem diagnoses involving their specialties. The PPDL team provides an ongoing point of connection between county-based Extension educators, the public and Extension specialists on campus; facilitating knowledge exchange and information about trends in lab samples to promote more informed recommendations for disease and pest management.

Tom C. Creswell

Botany and Plant Pathology Clinical Engagement Professor, PPDL

As Director of the Plant & Pest Diagnostic Laboratory (PPDL), I am responsible for overseeing daily operations and administration of the lab. The PPDL is an interdisciplinary lab, taking advantage of technical expertise from several departments in the College of Agriculture to provide diagnostic and identification services to our clients. Our lab serves as the state laboratory for the Indiana Department of Natural Resources (IDNR).
