Dr Marina Pais

Postdoctoral Scientist
Jonathan Jones Group

As postdoctoral researcher in Prof. Jonathan Jones’ group, I work on the development of new UK potato varieties with late blight and potato cyst nematode resistance, reduced bruising and improved processing quality. These have the potential to be better for the environment and for consumers, as well as cheaper to produce. This project has been funded by the BBSRC as part of the Horticulture and Potato Initiative (HAPI) and more information about it can be found here. In addition to leading the experimental work related to the HAPI project, I participate in communication and outreach activities that aim at explaining the scope of our work to the general public. I have a longstanding interest in plant biotechnology and in the study of the interaction between plants and the environment, with a focus on Solanaceous crops. I obtained my Ph.D. from the University of Buenos Aires (Argentina), where I studied signal transduction in tomato and potato plants, in relation to abiotic stress responses and tuberization signalling. During my first postdoc in the group of Prof. Sophien Kamoun, I gained a deep understanding of the late blight disease, working on the development of synthetic disease resistance genes with expanded recognition spectrum and participating in pathogenomics projects with a focus on pathogen effector genes. The HAPI project now allows me to further develop my interest in crop-applied research while strengthening the links between science and society.
