Project Description

Plant-microbe and plant-plant interactions are key drivers of crop health, resilience, and productivity, and are increasingly viewed as essential components of sustainable agricultural systems. Exploiting these biological relationships offers a promising route to reduce reliance on synthetic pesticides while improving the efficiency and stability of plant-based food production.

This PhD project will investigate how plant-plant and plant-microbe associations influence plant secondary metabolism, with a focus on utilizing phytochemical profiles for sustainable crop production. The candidate will study how plant-plant and plant-microbe interactions modify metabolite production and allelopathic traits in crop plants.

Using targeted and untargeted LC-MS-based metabolomics, the project will characterize interaction-driven shifts in plant chemistry and relate these to functional outcomes to plant resistance in applied crop production. The overall aim is to better understand how natural biological associations can be utilized to support sustainable crop production and reduce pesticide dependence.

Why This Scholarship Stands Out

This PhD is unique because it combines chemical ecology, metabolomics, and sustainable agriculture to address a pressing challenge: reducing pesticide dependence. Plant-plant and plant-microbe interactions influence plant secondary metabolism – the production of defensive compounds. Understanding these interactions could lead to crop varieties or cropping systems that rely less on synthetic pesticides. The project uses LC-MS-based metabolomics (targeted and untargeted) to characterize phytochemical shifts. For a student interested in chemical ecology, plant biochemistry, or sustainable agriculture, this is an opportunity to do research with direct applications for pesticide reduction.

Key Responsibilities

• Investigate how plant-plant and plant-microbe associations influence plant secondary metabolism
• Study how interactions modify metabolite production and allelopathic traits in crop plants
• Use targeted and untargeted LC-MS-based metabolomics to characterize interaction-driven shifts in plant chemistry
• Relate chemical shifts to functional outcomes for plant resistance
• Conduct fields, common-garden, and greenhouse studies

Candidate Profile and Eligibility

What They Offer

My Application Tips

1. Highlight your metabolomics experience – LC-MS experience is desired
2. Emphasize chemical ecology or plant biochemistry background – Understanding of plant secondary metabolism
3. Show field and greenhouse research experience – Conducting studies in multiple settings
4. Demonstrate interest in sustainable agriculture – Pesticide reduction is the project goal

Who Should Apply

This PhD is perfect for a student with a background in agroecology, biochemistry, chemical ecology, or microbiology who wants to work on reducing pesticide dependence through understanding plant interactions. If you are interested in how plant-plant and plant-microbe interactions affect plant chemistry, and want to use LC-MS metabolomics to characterize phytochemical patterns, this project offers training across chemical ecology, metabolomics, and sustainable crop production.
