Proteomics, peptidomics, bioinformatics and biological mass spectrometry to investigate plant-pathogen interactions. Research is mainly focused on Puccinia triticina (wheat leaf rust), with emphasis on effector proteins and peptides, and on Fusarium graminearum, with emphasis on mycotoxin biosynthesis regulation. Our lab collaborates extensively with other researchers who use proteomics but lack the expertize, equipment and software to address complex biological questions. These projects currently involve complex analyses using stable-isotope-labelled tags, label-free quantification, and analyzing post-translational modifications (phosphorylation and redox modifications).
