Research Interests

Biomass processing and the associated quality control or product characterisation along with bio-derived composite engineering with a focus on interface chemistry. Specialising mainly in areas of materials characterisation, polymer chemistry, and analytical chemistry. My research has involved analyse of carbonaceous materials (including biochars, activated carbons, reduced graphene oxides, carbon nanotubes, fullerenes, carbon fibres and graphites) and polymers (thermoplastics and thermosets). Current research activity is mainly on the “Additive manufacturing and 3D and/or 4D printing of bio-composites” spearhead project which is part of the “Science for Technological Innovation” “National Science Challenge”.
