I joined the Field lab as a postdoctoral research fellow in January 2017 to work on the evolution of plant-fungal symbiosis. My research interests include how plants interact with different parasitic and/or symbiotic organisms. I am particularly fascinated by how plants evolved to defend themselves against abiotic and biotic stresses and forage what they need to persist today.
My NERC funded project focusses on the role of fungal diversity in the evolution of Earth’s land flora. I use physiological techniques to assess bi-directional transfer of carbon and nutrients in early-diverging plants and diverse fungal lineages. This investigation enhances our understanding of the role of fungal symbionts in the initial colonisation of the terrestrial environment, and subsequent plant diversification through the Paleozoic. This project may also play a crucial role in predicting the responses of plant-fungal partnerships to ongoing changes in atmospheric CO2 concentrations.
