Personal profile
Primary fields of research
Molecular ecology, population genetics and evolution of fungi with emphasis on biotrophic symbionts and parasites. Among the studied fungi are Fusarium, Penicillium, various Oomycota (Peronosporamycota) as well as the arbuscular mycorrhizal fungi (AMF) in Glomales and fungi associated with insects. We use rad-sequencing, microsatellites, SNPs, DNA sequencing in to generate markers for these studies. The project (BioMark) is using population genomics to associate genetic markers and phenotypic traits of Phytophthora infestans (Potato late blight) to predict emerging epidemics. Molecular diversity and population genetics of AMF fungi in agricultural fields and natural vegetation is studied from variation in various gene sequences. Evolutionary and demographic models based on coalescence and MCMC Bayesian statistics are used to explain fungal diversity and distribution patterns. Hierarchical joint species modeling and co-occurrence networks implemented in analysis of microbial community data.
