USDA-ARS Postdoctoral Research Fellowship in Weed Biology​/Physiology

USDA-ARS Postdoctoral Research Fellowship in Weed Biology/Physiology Description of Duties

This research is a component of ARS National Programs 305 (Crop Production) and 304 (Crop Protection & Quarantine). Throughout the course of this project, the participant will learn about project management by being a part of research aimed at identifying key differences in physiology, growth characteristics, photosynthetic capacities, adaptability, competitiveness, and responses to stress and other fitness criteria of invasive and wild-type versus herbicide-resistant weed biotypes.

The participant will collect and analyze data related to weed control, herbicide efficacy, and comparison of whole-plant physiological processes of herbicide-resistant weed populations with corresponding susceptible populations under controlled environmental conditions. These insights are important for predicting the ecological success of resistant populations and developing more sustainable, integrated weed management strategies. The project involves close collaboration with USDA-ARS scientists specializing in plant physiology, molecular biology, genomics, and herbicide resistance to advance understanding of resistance mechanisms and support the development of novel weed management solutions for problematic weeds in Mississippi cropping systems.

Through participation, the participant will gain experience managing growth chamber and greenhouse studies and establishing new experiments to investigate weed control, physiological responses, and herbicide resistance mechanisms.

The qualified candidate should be currently pursuing or have received a doctoral degree in one of the relevant fields (e.g. Agricultural Sciences, Botany, etc.). Degree must have been received within the past five years or anticipated to be received by August 15, 2026.

• Experience in greenhouse, field, and growth chamber research
• Knowledge of crop production systems of major crops and weeds
• Strong background in weed biology, herbicide resistance research, and field/greenhouse/growth chamber experimentation
• Experience with physiological measurement tools and spray chambers (e.g., LI‑COR gas exchange systems, chlorophyll fluorometers, research track sprayers)

The participant will receive a monthly stipend commensurate with educational level and experience. The anticipated stipend range is $65,000 annually.

Proof of health insurance is required for participation in this program.
