From 1994 to 1996 he was Marie-Curie Fellow at the Department of Virology of
Wageningen University (the Netherlands) working with Prof. J. M. Vlak, before he moved to the plant protection service of the state of Rhineland-Palatinate. From 1997 to 2009 he headed the research group Biotechnological Plant Protection at the Agricultural Service Centre in Neustadt an der Weinstrasse, where he addressed safety issues related to genetic engineering of maize and grapes and improved methods for biological plant protection using microorganisms and insect viruses. Since 2010 he is director of the Institute for Biological Control of the
Julius Kuehn Institute in Darmstadt. In 2006, he obtained a postdoctoral degree (Dr. habil.) of Genetics at the
University of Mainz, and since 2012 he is adjunct Professor at the
TU Darmstadt. Jehle's scientific work aims to investigate, develop, and evaluate methods of biological control for organic and integrated farming. His research focus is on insect viruses, their classification and phylogeny, their use as biological plant protection agents, and research into baculovirus resistance. In 2008 he was honored for this work by the Society of Invertebrate Pathology with the Founders´ Lecturer Award. The results of this research culminated in over 200 scientific papers and book contributions. == Publications (selection) ==
