In 2019, I obtained my BA in Natural Sciences (Plant Sciences) from the University of Cambridge. During my studies, I conducted a research project on the transmission of Cucumber Mosaic Virus by aphids in the group of Professor John Carr. Later that year, I joined Sebastian Schornack’s group as a research technician, where I worked with Dr Philip Carella studying plant immunity in the liverwort Marchantia polymorpha. In October 2020, I started my PhD in the Schornack Group, which focuses on a comparative characterisation of intracellular interfaces between filamentous microbes and plants.

Research Interests

My research interests lie in understanding the interactions between plants and microbes, both symbiotic and pathogenic. Specifically, I focus on the formation of intracellular interfaces, such as haustoria or arbuscules, which are crucial for nutrient exchange, defence, and communication between the host plant and filamentous microbes. Through identifying protein and lipid constituents of these interfaces, I aim to determine the extent to which mycorrhizal fungi and pathogenic oomycetes in roots and shoots share the same plant components and processes.
