His expertise is in leading the funding, planning, design and construction of large, complex, multi-agency infrastructure programmes, with a particular focus on post-disaster reconstruction of resilient infrastructure.
Warren’s research is focused on post-disaster decision-making, and the development of methods to incorporate quantifiable social benefits into infrastructure investment decisions.
Amila Wickramasekara is a PhD researcher attached to the Department of Civil and Environmental Engineering at The University of Auckland. In Amila’s PhD, he focuses on utilizing serious games for controlled experiments in construction project management research. In general, his research interest is to apply OR and Analytics to solve real-world decision-making problems. Before starting his PhD, Amila worked as a Senior Lecturer at the Department of Decision Sciences, Faculty of Management Studies and Commerce, the University of Sri Jayewardenepura in Sri Lanka. He completed his BSc (Statistics) at the University of Sri Jayewardenepura and MSc (Operational Research) at the University of Moratuwa in Sri Lanka.
Kian Wee Soh
Kian Wee Soh completed his MSc in Mathematics at the National University of Singapore and PGDE with specialisation in teaching at junior college (pre-university) level at the Nanyang Technological University/National Institute of Education. He has recently completed his PhD in Operations Research at the University of Auckland. His PhD thesis studied novel approaches for predicting surgery durations and evaluating sessions.
Kian Wee’s research interests include domination and graceful labelling (graph theory) as well as statistical modelling and machine learning (artificial intelligence).
Precision Driven Health
Mike O’Sullivan and Cameron Walker both work in projects and partnerships with Precision Driven Health, a public/private research partnership with the goal of stimulating and supporting research and development of digital tools to help people better manage their own health or the health of patients.
Professor Matthew Parsons PhD MSc BSc (Hons) RGN NZRN
Matthew holds the position of clinical chair in gerontology, a joint appointment between Waikato District Health Board and the University of Waikato. His role focusses on service development around older person health and the training of health professionals in the Midlands region. He has spent his career researching, implementing and evaluating new health services to improve the lives of older people and people with disabilities.
His particular area of interest concerns the creation of new evidence around health services in order to change health service behaviour and improve quality of service delivery.
Professor Paul Rouse PhD, MCom Accounting (1st Class Hons), BCom Accounting, CA
Paul Rouse’s research area is performance and productivity measurement with specialist applications to transport, education and health. Current research includes productivity modelling, case mix funding models, complexity, cost and performance in hospitals and revenue and cost management systems.
Dr Mohammed Adel Abdelmegid
Mohammed Adel is a Professional Teaching Fellow at the Graduate School of Engineering, mainly involved in engineering management-related courses. In addition to teaching and supervision of masters students, part of his role is to manage industry collaboration with the Graduate School of Engineering with a focus on maximising engagement through taught masters projects. Before moving to New Zealand, and while doing a master’s degree part-time, he worked for seven years as a structural and construction engineer in a number of major projects in the Middle-East such as the Hilton King’s Ranch Hotel in Egypt and the Holy Mosque of Mecca in Saudi Arabia.
Mohammed Adel finished his PhD in Construction Management in July 2020 at the University of Auckland. Through his PhD research, he developed a construction-specific framework to facilitate the formulation of conceptual models for construction simulation studies. The proposed framework was inspired by the Hierarchical Control Conceptual Modelling (HCCM) framework, developed by ORUA in 2015, integrated with other well-recognised frameworks and construction methodologies to suit the nature of construction systems. The framework was implemented in three major local and international construction projects to test its applicability for the construction industry.
Currently, Mohammed Adel is leading the Master of Engineering Project Management Programme at the University of Auckland. He is an active member of the Project Management Institute (PMI) and a certified Project Management Professional (PMP).
