Plant diseases causes significant problems in food production and plant pathology is the study of plant disease. Plant disease epidemiology is a subdiscipline within plant pathology, which studies of the development of disease in plant populations. My research focus is to study population biology of pathogens to understanding the occurrence, distribution, management and risk assessment of plant diseases in future agricultural and climatic scenarios. My aim is to study “real” problems and at the same time be able to answer basic biological questions.
Current and previous projects
- What defines a tree’s microbiome, the genotype, the stand or the landscape context?
- Leaves as spore traps for improved forecasting methods
- Find sources of durable resistance against yellow rust in wheat
- A study of crown rust to increase yield and quality of oats
- Early detection of plant disease based on molecular methods and spore traps
- Population biology of Puccinia graminis - Implications for the Epidemiology and Control of Stem Rust
In 2012 I completed my PhD thesis and the title of my project was ”Epidemiology and population biology of Puccinia graminis for control of stem rust in Sweden”. Within the project, I studied the biology and epidemiology to understand which the important elements are for spread and prognostication of stem rust. The particular with Stem rust in Sweden is the abundance of barberry, the alternate host, which enables the fungus to fulfil its sexual cycle.
