About us

We study secondary metabolites of fungi and plants. Our projects focus on mycotoxins, plant defense chemicals, molecular aspects of diseases caused by Verticillium longisporum, the diversity and biological functions of lignans in sesame, and plant root exudates. Our main tools are transcriptomics, gene manipulation in fungi, DNA-based analysis of microbial communities, advanced chemical analyses and nontargeted metabolic profiling.
