Research Interests
Carbohydrate-ligand discovery for recognition systems of biological, biomedical and biotechnological importance using carbohydrate microarrays; structural analysis of the protein-carbohydrate interaction by protein X-ray crystallography; neoglycolipid-based oligosaccharide microarray technology; ‘designer’ microarrays from microbial and plant polysaccharides (Glucans, LPS and others); glucan-binding proteins of the immune system e.g. Dectin-1; lectin-carbohydrate interaction in the immune system; mammalian and microbial carbohydrate binding proteins (e.g. lectins, CBMs and glycoside hydrolases, antibodies); host-pathogen interactions mediated by carbohydrate recognition; cancer-associated carbohydrate antigens; recombinant protein expression; protein crystallization; protein and protein-ligand structure determination.
