Core staff

Dr Graeme Hubbert
Dr Graeme HubbertOcenographer (Melbourne Office)

Graeme has spent most of his working life in oceanographic research and is internationally recognized for his atmospheric and ocean modelling work. In 1984 he was the first person in Australia to develop and use a 3 dimensional ocean model for coastal studies. In 1985 he was the first oceanographer employed by the Australian Bureau of Meteorology where he developed marine forecast models for Australia. In 1993, Graeme left the Government research world to establish Global Environmental Modelling Systems with the aim of applying state-of-the-art numerical modelling to the many atmospheric and marine environmental problems faced world wide by Governments and industry.

Matt Eliot
Matt EliotCoastal Engineer (Perth)

Matt has been providing elite coastal engineering input to GEMMS projects for almost 20 years through his own consulting company, Damara(WA).

Matt is a coastal engineer with over 20 years professional experience covering a wide range of coastal, estuarine and maritime projects around Australia. He has been involved in all phases of coastal engineering projects, including investigations, analysis, design, contract management, site supervision, project management, project review and structure failure assessment. Matt joined Coastal Information and Engineering Services in 1993 and assisted with the Dawesville Channel Project, design of Exmouth Boat Harbour and the Western Australian State Government maintenance dredging program.

From 1996 to 2002, Matt worked with Egis Consulting Australia (formerly CMPS&F Pty Ltd) as part of the marine and coastal engineering team. Highlight projects included review of Bunbury storm surge barrier operations, refurbishment of Broome Jetty and Coral Bay boat launching facility investigations, with a wide range of design and construction projects throughout Australia and Southeast Asia.

In 2002, Matt commenced work as an independent coastal engineer, through Damara WA Pty Ltd. Within this role, he has undertaken an increasing number of projects in collaboration with GEMMS, including dredge plume modelling at Dampier and cyclone impact studies for Efate and Tuvalu. Matt has worked with GEMMS on a wide range of projects throughout the Australian region, including wave climate assessments, wave load analyses and cyclonic inundation studies.

Tim Waldby
Tim WaldbyElectrical Engineer and Marine Measurement Manager (Perth Office)

Tim is an electrical engineer with over 20 years experience designing, deploying and maintaining ocean measurement systems in the coastal zone. Formerly Tim worked for MetOcean (now RPS MetOcean) for 20 years but joined GEMMS in 2012 to help expand our involvement in ocean measurement systems.

Tim has now moved into a sub-consultant role but remains an important and active member of the GEMMS team.

Other Key Scientific Collaborators

Dr Kathleen McInnesSenior Research Scientist, CSIRO Atmospheric Research
Dr Kathleen McInnes joined CSIRO Atmospheric Research in 1990. Since 1993, she has applied her numerical modelling skills to the modelling and understanding of tides and storm surges and the physical processes leading to coastal flooding. In recognition of some of her early work in coastal research, Kathy was invited to become a contributing author on the Coastal Zones and Small Islands chapter of the Second Assessment Report of the IPCC Working Group II.

Kathy has also undertaken and coordinated a large number of contract based-research projects focussing on coastal issues during her time at CSIRO. Recent projects have seen the development of algorithms to include the effect of waves on coastal sea levels to examine the role of storm surge and wave setup on extreme sea levels on the coast of NSW.

Kathy also remains an active contributor to the underpinning science of climate change research where her specific interest is the impact of climate change on severe weather systems that are responsible for coastal flooding and degradation. She has been involved in the analysis of Global Climate Model simulations of extra-tropical cyclones and severe winds. This analysis has involved the use of automated tracking software to monitor the frequency, intensity and movement of cyclones that develop in the simulated climates.

Ian LeProvost
Require a few Ian LeProvost has over 40 years experience in environmental impact assessment and management in coastal and estuarine environments, principally in Western Australia and the Northern Territory, but also in South East Asia and the Middle East.

Ian has also served three years on the Advisory Council to the Western Australian Environmental Protection Authority, and in 2000-2002 as a member of the Authority. He has also completed the Executive Management Programme at the University of WA Graduate School of Management.

During his career, Ian has managed or directed environmental planning, assessment, management and monitoring studies for most of the major coastal developments in Western Australia, including dredging programmes in the Pilbara, Cockburn Sound and the South West of Western Australia and Bali, oil and gas developments on the North West Shelf, Timor Sea, Papua New Guinea, Myanmar and Thailand, management plans for marine parks on the north west shelf and at Shark Bay, and residential, canal and golf course developments in the South West of Western Australia and Bali. In recent years he has developed expertise in EMS, compliance auditing, and community consultation and outrage management.

Currently Ian is self-employed and until recently was president of the Environmental Consultants Association of WA.
