Employment Opportunities

Postdoctoral Research Associate in Citrus Gene Editing and Genomics

The University of Florida is seeking a highly motivated postdoctoral research associate to use CRISPR/Cas9-mediated gene editing, gene overexpression, and genomics tools to engineer and select citrus (sweet oranges, grapefruit, etc.) for resistance to citrus greening (Huanglongbing), a bacterial disease that has devastated the citrus industry in the United States and many other countries. The successful candidate will be working at the University of Florida’s Gulf Coast Research and Education Center in the Tampa Bay area, Florida.


Primary research responsibilities will include generating additional gene-edited mutants, evaluating gene-edited mutants and transgenic lines for resistance to citrus greening, genome sequencing and analysis to identify mutations and off-target effects, transcriptome sequencing and gene expression analysis to understand mutation effects, and developing new molecular markers for disease resistance traits in citrus. Other research activities may include evaluating citrus mutants and transgenic lines for resistance to citrus canker and other citrus diseases, construction of new gene editing vectors, and genome sequence analysis. It is expected that research results will be published in high quality peer-reviewed journals and communicated through scientific presentations and stakeholder interactions.

Duration of Appointment:

The position is available immediately. The employment will be for one to two years.


  • Ph.D. degree in plant genetics, breeding, or related plant science fields.
  • Experience with artificial inoculation of plants with pathogens, evaluation of plant resistance to bacterial diseases, genome and transcriptome sequence analysis, gene expression analysis, CRISPR/Cas9-based gene editing, and molecular marker analysis.
  • Self-driven and having an excellent publication record.
  • Strong work ethics, motivation, and creativity.
  • Excellent communication and writing skills.
  • Experience in gene editing construct development, plant tissue culture, and genetic transformation will be a plus.

How to apply:

Send a cover letter with a statement of research interest, CV, and contact information for three references to Dr. Deng at

Closing date:

Applications will be reviewed until the position is filled.
