Developing new molecular tools to make plants more resistant to diseases.


My interest is in studying host-pathogen interactions focusing on developing new and sustainable ways to control plant diseases. I am currently working at the Department of Plant Breeding, Swedish University of Agricultural Sciences, Alnarp. My research focuses on to use of bio-nanoparticles engineered from harmless plant virus proteins to precisely target and deliver fungicides and biological substances against plant pathogens.



Spray-induced gene silencing technology to control plant diseases.

Development of Bio-nanocarriers for the targeted delivery of pesticides/ fungicides and biologicals for precision farming (FORMAS Swedish Research Council for Sustainable Development).
