**About the Editor**

**Łukasz Stpie ´n** is a Full Professor of Agricultural Sciences at the Institute of Plant Genetics, Polish Academy of Sciences, Poznan (Poland). He earned his M.Sc. diploma in Plant Biotechnology (1999) ´ at the University of Life Sciences in Poznan, Poland. He then completed his Ph.D. (2005), working ´ on the identification of resistance genes in wheat, and his habilitation (2014), studying mycotoxin biosynthetic genes in *Fusarium* species (2014), both at the Institute of Plant Genetics, Polish Academy of Sciences, Poznan. Currently, Prof. Stpie ´ n is the Head of the Department of Pathogen Genetics and ´ Plant Resistance at the IPG PAS in Poznan. He is also the leader of the Plant–Pathogen Interaction ´ Team of the same Department. He has co-authored more than 60 research articles and reviews in JCR-listed journals, 4 patents and ca. 100 conference abstracts. He also supervised several Bachelor's, M.Sc. and Ph.D. theses. As a reviewer, he performed ca. 150 reviews of scientific articles and reviewed international Ph.D. theses and Horizon 2020 proposals as an Expert of the European Commission. Prof. Stpien has been a visiting researcher at Technical University in Munich (Germany); Institute ´ of Epidemiology and Resistance, Aschersleben (Germany); Institute of Sciences of Food Production ISPA, CNR, Bari (Italy); and Technical University of Denmark, Lyngby (Denmark). His current research interests include plant–pathogen interaction studies using molecular, metabolomic and proteomic tools; using filamentous fungi for biotransformation of bioactive compounds; and looking for new tools for controlling feed and food contamination with fungal pathogens and mycotoxins.
