I joined the University of Leeds in 2016 as a postdoctoral researcher in cell wall biology within the plant centre. I am part of a cross-disciplinary project looking at the biophysical properties of plasmodesmatal cell wall domains.
I obtained my PhD in 2016 from the University of Sheffield where I worked across three departments to look at the role of cell walls in the functioning of stomata.
My main research interest is in the structural composition of cell walls. I am interested in understanding how cell walls are formed, maintained and modified and in understanding the relevance of this to plant functioning. I am particularly interested in the dynamic nature of the cell wall which changes between tissues, throughout the plant development and in response to numerous external stimuli. Better understanding this dynamic modification of the cell wall and how this regulation integrates into other signalling pathways within the plant is a fascinating area of research and may allow for targeted modification of plant cell walls as a mechanism to improve plant performance.
My current research aims to understand the cell wall microdomains surrounding plasmodesmata and their role in facilitiating and/or regulating cell-cell signalling in plants. Plasmodesmatal channels are essential for cell-cell communication and dynamic regulation of the cell wall component callose regulates their aperture and thus signal flux. In this research I am trying to understand how callose integrates into the wider cell wall, what other cell wall components have a role to play at the plasmodesmata and how their regulation affects symplastic transport between cells.<h4>Research projects</h4> <p>Any research projects I'm currently working on will be listed below.
