Suraya Mohamad Nadzir

Over the 16 years of my career as a Principal Researcher, I have developed a strong foundation in industrial research & technical services works. I have enhanced my ability to gather and analyze data, identify risk associated with material damages, and create high value creation projects deliverables. This experience has provided me with a solid understanding the needs of research, laboratory management as well as site inspection of power and chemical industries, which I believe will be invaluable in overseeing the generation unit overall role at TNB Research.
