Biography:

Currently, I am a Senior Lecturer/Research Fellow at COLAB, Faculty of Design and Creative Technologies. For last 10 years, I was working as a Research Fellow at Deakin University, Melbourne; worked as a Research Assistant/Lecturer at AUT University; and free lancing/contract Design Engineer/CAD Drafter for reputed bulk packaging equipment and chemical storage tanks manufacturers in Auckland, New Zealand. Published considerable number of journals, technical articles and conference paper on Manufacturing Science and Engineering. Post-graduation specialization includes Product Design and Development. I have considerable European work experience in managing and working in dynamic production environments. Experienced in 3D CAD modelling using various software: Solidworks, Autodesk Inventor and Pro-Engineer (now CREO). Considerable work experience using FEM software: ANSYS. Attended Workshops/ Training program on DELCAM, ANSYS; learning, teaching technical education and research methodology.

Teaching Areas:
