Dr Karnika De Silva
Karnika has her PhD from the University of Aston, UK. Her background is in Polymer Technology and she has interests in sustainable polymer composites and coatings. She contributes to Product Accelerator as the Senior Industry Materials Specialist and the Project Lead in Soft Materials, Recycling and Bioprocessing Portfolio and takes responsibility for managing the NZPA established National Testing Registry. Karnika is engaged in several industry projects involving multidisciplinary technologies.
Karnika has won numerous international awards including Commonwealth scholarship and funding from NSF, NSERC, CIDA, UNIDO, CFC and from the Malaysian government to work on different assignments overseas. She has both industry and academic experience and before migrating to New Zealand she served as the Deputy Director of Research (Technology) at the Rubber Research Institute of Sri Lanka.
Research | Current
I am currently involved in:
* development of functionalised coatings, composites and rubber products for various technology platforms
* undertake testing requests through the National Testing Registry established for the benefit of the manufacturing industry
* development of fire retardant plastics and do statistical analysis on Cone Calorimeter results to assign group numbers specified in the BRANZ building code
* R&D in collaboration with other local and international universities, institutes and companies to establish new export markets and to provide new products and technologies
* R&D projects on natural and environmentally biocides and their hybrids to cover a wider spectrum of antimicrobial efficacy
The projects i have undertaken have delivered on time and on budget, meeting milestones and deliverables, something in which I take pride. I have established strong industry engagements locally and internationally, connecting supply chain partners. I have demonstrated a record of innovation in new areas of research. I have contributed to commercial projects involving company contributions that impacted to enhance the company revenues significatly.
