Dr Nihal Jayamaha MEng, PhD

Senior Lecturer

Doctoral Supervisor
Engineering Group

Most of my research is based on quantitative research aimed at developing and testing theories on organisational outcomes improvement (e.g. product quality, service outcomes, productivity). Thus, I am quite familiar with the relevant literature, the industry context (part of which come from my 18 years of experience as a practising engineer in utility organizations), and the quantitative techniques being used in theory testing related to organisational outcomes improvement. More specifically, I consider myself an expert in the following statistical techniques: structural equation modelling (both covariance based, and variance based); factor analysis and related methods; linear and non-linear modelling; design of experiments; and statistical quality control/SPC. As such my teaching also reflects above areas to undergraduate and postgraduate students.

At the moment I do not have capacity to accommodate additional PhD students, but in the future, I would like to hear from students who are interested in conducting research in “sustainability” and/or “process improvement” at firm-level.      

I am an electrical engineer-turned-lecturer in quality management. Prior to taking up my lectureship in quality management in early 2009 and doctoral studies (2004-2008) which preceded that, I worked in electrical utility companies in Asia and the Middle East for 19 years specializing in operations, quality assurance, auditing (quality),  and project management.   

As a senior lecturer, I teach, supervise, and conduct research in many areas:  industrial management, statistical modeling in social research, quality control and quality improvement,  healthcare process improvement, performance measurement, and operations management.
