# Johannes Hallmann

Johannes Hallmann (born February 23, 1964, in Zeven, West Germany) is a German agricultural scientist of phytomedicine. He is a scientific adviser at the Julius Kühn-Institut, the Federal Research Institute for Cultivated Plants, the Institute for Epidemiology and Pathogen Diagnostics in Münster, the University Professor for Nematology and the President of the German Phytomedicine Society.

## Life and work

Johannes Hallmann studied agricultural sciences with a focus on plant production at the Rheinische Friedrich-Wilhelms-Universität Bonn. At this university, he was promoted in 1994, where he was also habilitated with Venia legendi in the field of plant diseases.
Research stays led him to To the American Auburn University in Alabama, the Nuriootpa Research Center in Australia, and to Kenyatta University & ICIPE in Kenya. He also worked as a FAO consultant for Farmers Field School in Indonesia at the Department of Plant and Microbial Biology at the Department of Plant and Microbial Biology at the Yezin Agricultural University, Myanmar, as well as at the Twinning Project: Strengthening the Phytosanitary Inspection to Croatia and Ukraine.
Since 2005, he has been teaching at the Rheinische Friedrich-Wilhelms-Universität Bonn in the field of phytomedicine (areas: nematology and biological plant protection) as a lecturer. Since 2006 he is lecturer at the University of Kassel, from 2014 as Apl. Professor for the field of nematology in the department of ecological agricultural sciences and since 2016 he has an additional professorship at the Humboldt-Universität zu Berlin in the field of phytomedicine.
