Dr. Thomas Jung (TJ)


has more than 20 years of experience in plant pathology and is one of the most renowned Phytophthora experts in the world. He was awarded the Arnold-Sommerfeld Award of the Bavarian Academy of Sciences. Through his scientific career TJ has studied the diversity, ecology, pathogenicity and evolution of Phytophthora species, their impacts on natural and semi-natural ecosystems, their pathways and possible management and control options for Phytophthora diseases. His major scientific achievements were (1) the first evidences of Phytophthora species being involved in widespread forest declines in Europe; (2) the development of new methods for the isolation of Phytophthora spp. and for the assessment of fine root damages; (3) the coordination of the largest forest disease survey in European history (Alnus mortality in Bavaria) which showed for the first time the importance of the nursery pathway in spread of Phytophthora spp. to natural ecosystems; (4) first demonstration of the interaction between invasive Phytophthora pathogens and climatic extremes triggering a large-scale epidemic forest decline (Fagus sylvatica); (5) the detection and description of more than 30 new Phytophthora species. Stations in his professional career were the Technical University of Munich, the Bavarian State Institute of Forestry, the Centre for Phytophthora Science and Management (Murdoch University, Australia), the University of Extremadura (Plasencia, Spain), and the University of Algarve (Faro, Portugal).

TJ published 52 papers in international peer review journals and his current h index at Scopus is 26, with 2185 citations. He was speaker or keynote speaker at 18 international conferences and 12 meetings of international networks. TJ completed the supervision of 9 PhD and 5 Master students, and gave training courses in Phytophthora methods for PhD students, Post-docs and senior researchers from 46 international research institutes. This extensive dedication to postgraduate training and his leading role in the international networks International Union of Forest Research Organizations (IUFRO) Unit 7.02.09 Phytophthora in Forests and Natural Ecosystems (Co-Chair), EU COST Action FP 0801 – Established and Emerging Phytophthora: Increasing Threats to Woodland and Forest Ecosystems in Europe (working group leader) and COST Action FP 1002 – Pathway Evaluation and Pest Risk Management In Transport (Vice-chair) and his participation in the ‘European network on emerging diseases and invasive species threats to European Forest Ecosystems’ and in IUFRO Unit 7.03.12 Alien Invasive Species and International Trade enabled TJ to build up a large network that includes most of the leading international Phytophthora researchers.

TJ cooperated with many international research groups on a wide range of Phytophthora topics and conducted research in 16 countries of Europe, in Australia, in North and South America, in Taiwan and Vietnam. TJ participated in 18 national and 4 international research projects in 11 countries. Recently, he was the Principal Investigator of the exploratory project QuerResist Screening of Asian oak species for potential resistance to Phytophthora spp., funded by the Portuguese Foundation for Science and Technology (FCT), and coordinated the Working Group ‘Detection and early warning of fungal and oomycete pathogens’ in the European BiodivERsA R&D project RESIPATH.
