Postdoctoral Research Associate I, Ecology & Evolutionary Biology

A postdoctoral research position funded by the U.S. Department of Agriculture is available to work with Dr. Katrina Dlugosch at the University of Arizona on the ecological genomics of the evolution of the invasive plant yellow starthistle (Centaurea solstitialis). This project studies the evolution of species interactions during range expansion and their impact on the spread of invading plant populations. We have found large differences in the microbial communities associated with yellow starthistle across its range, and evidence that microbial variation alters invader performance. This position will lead efforts to understand the genomic basis of these changes and their impacts on the ecology of invasion, including mapping the genetic basis of microbiome variation in the host plant genome.

We are seeking a postdoctoral researcher with interests and experience in these areas. In addition, there will be opportunities for the postdoc to propose new research directions and to be involved in the mentoring of students.

The successful candidate will join an active lab of undergraduates, graduate students, and postdocs focused on the rapid evolution of plants in response to novel environments. https://www.dlugosch-lab.net/

This is a one-year appointment.

Outstanding U of A benefits include health, dental, vision, and life insurance; paid vacation, sick leave, and holidays; U of A/ASU/NAU tuition reduction for the employee and qualified family members; access to U of A recreation and cultural activities; and more!

The University of Arizona has been recognized for our innovative work-life programs. For more information about working at the University of Arizona and relocations services, please click here.
