Position Summary
The Root and Tuber Crop Lab (RTC Lab) in the Department of Plant Science at The Pennsylvania State University invites applications for a Postdoctoral Scholar position focused on investigating root system architecture (RSA), root anatomy, carbon allocation, and sink–source dynamics in sweetpotato under nutrient-limited, drought, and heat-stressed environments.
This position provides a unique opportunity to lead integrative research combining functional phenomics, root hydraulic conductivity measurements, carbohydrate metabolism studies, and SimRoot modeling to better understand physiological and anatomical mechanisms driving sweetpotato productivity under multiple abiotic stresses.
Key Responsibilities
Design and conduct experiments to characterize root system architecture and anatomy under field and controlled conditions.
Investigate carbon allocation, sink–source dynamics, and carbohydrate metabolism under nutrient stress and environmental constraints.
Assess root hydraulic conductivity and explore links between water transport, nutrient acquisition, and plant productivity.
Implement SimRoot modeling to simulate root growth dynamics and performance trade-offs under varying soil conditions.
Integrate physiological, anatomical, and modeling datasets to identify key traits for improving stress tolerance.
Analyze large, multidimensional datasets using advanced statistical and computational approaches.
Prepare peer-reviewed manuscripts, contribute to grant proposals, and present findings at conferences.
Mentor undergraduate and graduate researchers and collaborate with faculty and interdisciplinary teams.
Required Qualifications
Ph.D. in Plant Science, Crop Physiology, Agronomy, Plant Biology, or related discipline.
Expertise in root system architecture, plant physiology, or root phenotyping.
Strong background in carbon allocation, plant–soil interactions, and/or nutrient-use efficiency.
Proven publication record in peer-reviewed journals and strong scientific communication skills.
Ability to work independently and as part of a collaborative, cross-disciplinary team.
Selected candidate must posess a U.S. driver's license and will be required to complete a motor vehicle record background check.
Preferred Qualifications
Experience with sweetpotato or other root/tuber crops in field and controlled environments.
Familiarity with image-based phenotyping pipelines and root hydraulic measurements.
Experience with SimRoot modeling or other computational frameworks.
Knowledge of nutrient-use efficiency and plant responses to drought and heat stress.
Interest in fostering collaborations across research groups at Penn State and beyond.
Appointment Details
• Position Type: Full-time, 1-year appointment, renewable based on performance and funding.
• Start Date: Flexible; preferred Fall 2025.
• Location: University Park, Pennsylvania.
• Salary: Competitive, with full Penn State benefits.
