Job description

Job DetailsJob Location: Saint Louis - Saint Louis, MO 63132Position Type: Full TimeEducation Level: Graduate Degree

The Donald Danforth Plant Science Center is seeking a full-time postdoctoral researcher to join the Zhang Lab for a collaborative project focused on improving thermotolerance in pennycress, a promising oilseed cover crop.

Cover crops like pennycress play a vital role in sustainable agriculture - improving soil health, preventing erosion, and suppressing weeds - while also giving farmers a valuable second cash crop during the off-season. However, widespread adoption is currently limited by a key agronomic challenge: pennycress must be planted in late summer, when temperatures often exceed the thresholds required for successful seedling establishment. This postdoctoral researcher will investigate the genetic mechanisms that allow pennycress to survive and thrive during high-temperature planting windows, without compromising its cold tolerance. The work will involve pennycress plants grown under both greenhouse and field conditions, offering a rich, applied research experience with direct relevance to real-world agricultural sustainability.

The Zhang Lab, based at the Danforth Center in St. Louis, Missouri, studies how photosynthetic organisms, including green algae and land plants, respond to abiotic stresses such as high temperature and light, with a particular focus on how these stresses affect photosynthesis.

This position is part of an exciting multi-lab cluster hire initiative aimed at improving food and cover crops to advance global food security, agricultural sustainability, and innovation.

Responsibilities

• Use published or available omics datasets to identify gene candidates
• Grow, phenotype, and harvest pennycress plants in greenhouses or the field
• Perform photosynthetic measurements in pennycress plants
• Generate and characterize pennycress transgenic plants
• Summarize research results and write related manuscripts
• Mentor undergraduate and/or high school interns as needed
• Help coordinate the collaboration between different teams
• Contributes to related grant proposals with PI
• Perform other duties as assigned

Opportunities & Development

• Training in plant physiology (especially photosynthesis), omics, high-throughput phenotyping
• Engage with collaborative labs with expertise in cover crops, transformation, and genetics
• Highly collaborative, well-resourced environment with access to the Center's world-class core facilities, including the Plant Growth Facility, Plant Transformation Facility, the Advanced Bioimaging Laboratory, the Bioanalytical Chemistry Facility, the Data Science Core, the Phenotyping Facility, and the Danforth Field Research Site.
• Opportunities for professional development and networking.

Required knowledge, skills, and abilities

• Highly motivated, goal-oriented, and productive individual
• Conduct research projects in a timely manner, with the expectation of meeting deadlines
• Have great passion for plant science
• Strong attention to details
• Have strong background in molecular biology and/or genetics
• Be able to organize, multitask their time efficiently
• Work both independently and collaboratively within a collaborative and interactive research environment
• Effective communication skills and open-minded for scientific discussion
• Ability to produce high-quality oral and written research products
• Strong problem solving and critical thinking skills
• Candidates who have experience with photosynthesis, plant stress responses, or field research are especially encouraged to apply
• Live the Danforth Center values: Collaboration, Diversity & Inclusion, Innovation, Integrity & Respect, Environmental Sustainability, and Stewardship
