Herve Van der Heyden, Ph. D.

Current research and/or projects

Plant pathology. Understanding the factors that influence the development of fungi and oomycetes responsible for root diseases.  

Integrated pest management. Molecular monitoring of fungal and oomycete pathogens, fungicide resistance, pathogen diversity and metagenomics. 

Population ecology. Modeling metacommunities and understanding the impact of disturbances (anthropogenic and environmental) on population resilience.

Research and/or project statements

My work focuses on the phytopathology of soil-borne pathogens (fungi and oomycetes). More specifically, I am interested in the population biology of plant pathogens and the application of molecular and statistical techniques to model, monitor and improve our understanding of pathogen community dynamics, to anticipate and mitigate the risks of root disease development and make agrosystems more resilient.
