Polymer chemistry, experienced in producing carboxymethyl cellulose (CMC) from sago waste and convert to CMC hydrogels for medical uses and to microcapsule to be used in control release of drug delivery and also in preparing biodegradable plastics. CMC and other carbohydrates are also used to prepare halloysite nanotubes for application in electronic packaging and automotive industry.

Research interest is in developing new biodegradable polymers using plant waste and currently focusing on preparing low cross-link CMC hydrogel to be used as control release device for anticancer drug and slow release device for application of fertilizer in agriculture.
