My research interests include population biology and genetics of fungal pathogens and genetics of host plant resistance. I am particularly interested in the rust fungi and their interaction with the host plants. I did my PhD on the population genetics of the willow leaf rust fungus Melampsora larici-epitea.
I am currently working on identifying rust resistance genes in willow by QTL-mapping in the project “High and sustainable biomass production of Salix: bridging molecular genetics, ecophysiology and plant breeding”. The aim of the project is to develop molecular markers that can be used in marker assisted breeding of willow. You can read more about the project on the SAMBA (Salix Molecular Breeding Activities) homepage.
I am also working on the population biology of the Scots pine blister rust fungus, Cronartium flaccidum/Peridermium pini. Epidemics of blister rust are currently causing serious damage in young pine forests in northern Sweden. By use of molecular markers we analyze the genetic composition of the fungal populations and learn about the spreading pattern of the disease.
