Project Description

Plant-associated bacteria produce an enormous diversity of metabolites and bioactive compounds that can affect plant health, the majority of which have not been characterized. Understanding how these compounds influence plant responses to environmental stressors like drought is especially important because water availability is one of the major environmental constraints on plant growth and agricultural productivity. Identifying bacterial metabolites that help plants maintain growth and survive under drought conditions could reveal new mechanisms of plant-microbe interaction and provide new tools for improving plant resilience to drought stress.
The overall goals for the project are: 1) establish a reliable experimental system for measuring drought responses in Arabidopsis, 2) identify bacterial strains or compounds that improve plant performance during simulated drought conditions, and 3) investigate the biological basis of promising drought-protective effects.


Research Tasks: Plant growth and maintenance, bacterial culture, preparation of media and experimental treatments, drought-stress assays, data collection and analysis, literature review, experimental troubleshooting, scientific writing, poster presentation.
As the project progresses, the student may also participate in experiments designed to characterize promising bacterial treatments and identify candidate bacterial compounds or pathways associated with drought protection.


Skills that research assistant(s) may need: Required: Willingness to learn, reliability, attention to detail, scientific curiosity
Recommended: A strong background in biology.

Mentoring Philosophy

I will provide close guidance at the beginning of the project as the student learns laboratory techniques, experimental design, record keeping, and data analysis. My goal is to enable undergraduate researchers to understand the scientific reasoning behind their experiments, not just learn to follow protocols. As students gain confidence and experience, they will be able to work with more independence. I want students to feel comfortable asking questions, discussing issues or errors, and troubleshooting unexpected results. My goal is to help students develop strong research skills and the confidence to think independently about scientific problems.
