Dr Pramila Gamage is a product of Faculty of Engineering, University of Peradeniya. Pramila graduated with a BSc (Hons) in Production Engineering in 2008 and was appointed as a temporary lecturer in 2008 (September) and subsequently as a lecturer (probationary) in June 2010. In January 2012 Pramila went on study leave to follow a PhD to specialise research on quality engineering. In January 2016 she earned her PhD from Massey University, New Zealand and returned to Sri Lanka (Faculty of Engineering) to continue her service as a lecturer. For the doctoral study Pramila developed a theoretical and practical framework to explain how Taguchi’s robust parameter design approach to quality improvement could be integrated in a Lean manufacturing environment. Pramila has a special interest on quality improvement using ‘statistical thinking’ (statically designed experiments and statistical process control are integral parts of statistical thinking). As industry projects, currently Dr Gamage is studying how quality and productivity of casting products and industrial gloves could be improved using statistical thinking.
