Researching Microbial Communities

Don’t have time to read an entire thesis? Here are the highlights from Susanna’s PhD research in microbiology at the University of North Carolina in Chapel Hill.

Bacterial Interactions

Understanding how bacteria respond to each other under all types of circumstances

As a researcher in the lab of Dr. Elizabeth Shank, Susanna studied how microbes behave when they are in mixed communities with each other. Her thesis focuses on how these interactions between bacteria in the soil and on the roots of plants.

Plant Microbiomes

Experimenting with plants and bacteria to determine how communities of bacteria attach to roots

Susanna helped create a new system to measure how bacteria maintain their associations with plant roots and affect each others’ behaviors. Learn why and how this happened by watching a short interview with the Journal of Video Education

Plant Growth-Promoting Bacteria

Using microbes to increase crop production and reduce environmental impact of agriculture

Microbes can help plants grow by protecting them from pathogens, helping them take up water, increasing their productivity of chemicals and hormones… the list is seemingly endless!
