Dr Carla Eaton PhD

Lecturer in Genetics

Institute of Fundamental Sciences

My research focuses on interactions, or symbioses, formed between plants and fungi. I am particularly interested in the molecular mechanisms that determine whether a given interaction will be beneficial or detrimental. This is investigated using a variety of approaches, including gene replacement of predicted symbiotic regulators, and high throughput RNA sequencing of symbiotic mutants.
