  • Co-Principal Investigator-Value: $4.8 Million
  • Extension

    Dr. Amanda Hodges has authored or co-authored over 100 extension publications related to arthropod diagnostics and invasive species. During the 2012 meeting of the Southeastern Branch of the Entomological Society of America, Dr. Hodges was presented with the Distinguished Achievement Award in Extension. Specifically, Dr. Hodges is known for delivering innovative, hands-on plant pest diagnostic workshops in Florida, the southern region of the U.S., and the Caribbean. Dr. Hodges also provided initial key leadership for the launch of the National Plant Diagnostic Network (NPDN) online First Detector training program ( and the Protect U.S., Community Invasive Species Network Program ( During the 2011 meeting of the NPDN, Dr. Hodges was recognized as one of the team members involved in establishing the NPDN Partner Program, the Sentinel Plant Network. Dr. Hodges currently coordinates the Florida First Detector project (, and the UF Plant Protection Website ( Dr. Hodges' projects often encompass interdisciplinary teams and multiple institutions.

  • Research

    The Biosecurity Research & Extension (BRE) lab focuses on investigating invasive, arthropod species of potential concern to Florida's landscape, natural areas, and agriculture. The BRE lab creates a variety of extension pest diagnostic guides, fact sheets, and e-learning modules. Educational materials produced by the BRE lab are Florida, southern regional, or national in scope, depending upon the project's purpose and funding source. Additionally, BRE research is translated into extension workshops and publications for Florida clientele.

    • Program Overview

      Dr. Amanda Hodges serves as the Director of the interdisciplinary Doctor of Plant Medicine (DPM) program

      As the DPM Director, Dr. Hodges is the primary faculty point-of-contact for prospective students, coordinates the DPM faculty advisory committee, coordinates public relations components, interfaces with external stakeholders, provides instruction for some DPM-specific courses, reviews all program of study documents, prepares annual reports, supervises and edits the DPM Newsletter (DPM News), supervises the production of promotional videos on the YouTube channel and the overall social media presence on Facebook, Instagram, and Twitter, supervises the DPM Academic Advisor, and completes other administrative tasks as issues arise.

      Dr. Amanda Hodges is also the leader for the University of Florida, Biosecurity Research and Extension Laboratory. Her research and extension interests focus on invasive arthropod species of potential concern to Florida’s landscape, natural areas, and agriculture. The research and extension activities of Dr. Hodges are supported primarily through external grants and contracts. Currently, Dr. Hodges primarily accepts graduate students enrolled or co-enrolled in the DPM Program in her laboratory.
