Research interests

Dr Matevz Papp-Rupar, Molecular Plant Pathology PhD, Biotechnology MSc, is a research leader in the pest and pathogen ecology team at NIAB in East Malling, with over 10 years' experience in plant pathology. His early research at the National Institute for Biology, Slovenia included detection and characterisation of Potato virus Y and grapevine yellows phytoplasma (Ca. Phytoplasma vitis) in pathogen hosts, wild plant species and insect vectors.

During the post-doctoral research at University of Nottingham he led InnovateUK funded research on UV-induced plant defences to control grey mould (Botrytis cinerea) in tomato and cut rose pre- and post-harvest production environments in collaboration with APS Ltd and Flamingo Flowers.

He joined NIAB in 2018, where he focuses on development of sustainable, ecological approaches for control of plant pathogens and improving resource use efficiency in horticulture. His main research areas are biocontrol potential of apple endophytic communities for control of apple canker (Neonectria ditissima), bacteriophage control of bacterial canker (Pseudomonas syringae) on cherry, natural resistance of UK ash trees to ash dieback (Hymenoscyphus fraxineus), microbiome interventions for control of crown rot (Phytophthora cactorum) in strawberry and the use of biostimulants in strawberry and raspberry production to reduce water and fertiliser use.

He is a member of British Society for Plant pathology (BSPP), International Society for Microbial Ecology (ISME), International Society for Horticultural Science (ISHS) and American Phytopathology Society (APS) and International Society for Molecular Plant-Pathogen Interactions (IS-MPMI).

He communicates research to growers and presents papers at national and international conferences and has over 15 peer reviewed articles with 288 citations and a h-index of 10 (Google Scholar). He regularly engages with growers and other industry stakeholders on events including AHDB, BIFGA, Fruit Focus, NIAB open days and webinars. 

He currently manages commercial projects funded by the industry, applied research projects funded by EU Interreg and AHDB SCEPTREplus and fundamental science projects funded by BBSRC with and without industry co-funding (Worldwide Fruit, Avalon, Scripps).  He is a reviewer for journal including Plant Pathology, BioControl, MDPI Agronomy and Frontiers in Plant Science.
