Research Scientist

Molecular pathologist studying Fusarium infection of cereals

Current research and/or projects

I am applying genomics and molecular biology to understand how the fungal pathogen Fusarium graminearum interacts with and infects cereal crops, and to characterize the biosynthesis and regulation of secondary metabolites, especially mycotoxins, of Fusarium species.

Research and/or project statements

Durable Fusarium Resistance

Mycotoxin biosynthesis and regulation in Fusarium graminearum

Characterization of new phytotoxic cyclic peptides of Fusarium graminearum

Genomic diversity and mycotoxigenic potential of Fusarium species in Canada
