I am Associate Professor at the School of Biology/FBS and UKRI Future Leaders Fellow. During postdoctoral stays at Cold Spring Harbor Laboratory (New York, USA) and at the John Innes Centre (JIC) (Norwich, UK), I gained extensive experience in plant, cell and molecular biology applied to investigate the regulation of intercellular symplastic communication. As a group leader, I pursue the cross-disciplinary aspect of my research through active collaborations with the Department of Physics and Astronomy, the Astbury Centre for Structural Biology, the Braggs Centre for Material Research and GFEI at Leeds. My work has produced papers of high academic impact. Research in my lab was/is funded by EPSRC, The Royal Society, UKRI and Leverhulme Trust. I have also received industrial and impact funding to work with diverse industrial stakeholders.
I have published pioneering work on callose metabolism and function in the regulation of plasmodesmata and symplastic signalling (Proc Natl Acad Sci USA. (2009) 106,3615-20; Dev. Cell. (2013) 26,136-47; Proc Natl Acad Sci USA. (2013) 110,9166-70; Frontiers Plant Sci. (2014) 23 (5):212). I also collaborated in addressing the plasmodesmata proteome and membrane composition (PLoS ONE (2011) 6,e18880; Plant Cell (2015) 27, 1228-1250) and the relations between symplastic and apoplastic loading (Plant Physiology (2016) 172,1876–1898). These publications had significant impact on the scientific community and were highly reccomended by Faculty 1000. More recently, my work (funded by the Leverhulme Trust) focuses on dissecting the physico-mechanical properties of structural component at plasmodesmata domain and the function of β-1,3-glucan, callose, and cellulose as regulators of cell walls and intercellular signalling.

Our research aims to reveal the molecular factors regulating plant development and response to the environment, which can be applied in the development of strategies that underpin crop improvement and enhanced agricultural sustanability. Current projects focus in the regulation of plant microchannels (called Plasmodesmata) that connect the cytoplasm of neighboring cells; to communicate proteins (e.g. transcription factors), RNAs and other macromolecules that coordinate development and response to biotic and abiotic cues.
We apply a number of genetic and cell biology tools and resources to identify how plasmodesmata communication influences plant growth and also use cross-disciplinaries approaches (soft polymer physics, computational modelling etc) to understand the influence of cell wall components and mechanical properties on intercellular molecular flux. We also design strategies to explot the properties of these cell wall polymers in biomaterial development.
