Current Positions:

Snr Research Fellow - Faculty of Engineering


Phil is an Engineering Geologist and his principal area of interest lies in landslide risk management, landslide monitoring and GIS applications. Currently, Phil is a Senior Research Fellow in the School of Civil, Mining and Environmental within the Faculty of Engineering at the University of Wollongong. His research at Wollongong is industry based where he collaborates with the Wollongong City Council, the NSW Roads and Traffic Authority and the NSW Rail Corporation.
Phil has a PhD from the University of Wollongong (1998), a Masters in Applied Science from the University of New South Wales (1992) and a BA with Honours from the University of Adelaide (1984). Prior to his PhD, Phil worked as an engineering geology consultant in the Sydney Basin region for 7 years and before that as an exploration and petroleum geologist in various areas of Australia based out of Adelaide and Perth.

Research Interests:

* Engineering Geology
* Landslide Inventory Development within New South Wales
* Landslide Susceptibility and Hazard Assessment and Zoning within
the Wollongong City Council Local Government Area specifically,
but also for the wider Sydney Basin region
* GIS based methods applicable to both of the above, specifically
knowledge based 'data-mining'
* Continuous near real-time monitoring along at a range of selected
landslide and structural monitoring sites in collaboration with
the NSW RailCorp, the RTA and Wollongong City Council
* Continuous near real-time monitoring in collaboration with
Geelong City Council at Clifton Springs
* Continuous near real-time monitoring in collaboration with
Mineral Resources Tasmania Real Time Monitoring at the Taroona
landslide in Hobart - one of Australia's largest urban landslides
* The continuous monitoring has direct real-time Risk Management
implications of course, as it provides a near real-time heads up
on site developments, and thats the main reason why Authorities
are actively persuing this technology. However, our main research
interest is that the continuous record of movement, pore water
pressure and rainfall allows us to examine in detail the
relationships between these parameters and quantitatively assess
the frequency and magnitude of displacement
* Development and teaching of post graduate level/CPD courses in Geology for
Engineers, Engineering Geology and Field Techniques for Landslide Assessment

Professional Activities:

" Managing operations of Landslide Hazard and Risk research team at the University of Wollongong, Faculty of Engineering. Includes support of three main industry partners;
" The Wollongong City Council (1993 to current, with funding support approved to 2020)
" Rail Corporation (1997 to 2003, 2005 to 2015)
" The Roads and Traffic Authority of New South Wales, (2004 to 2020)
" Development of Geographic Information System based Wollongong Landslide Inventory which has been referenced by significant infrastructure projects in the City of Wollongong (e.g. the Risk Assessment of the Lawrence Hargrave Drive area between Clifton and Coalcliff, Mout Ousley Road and Bulli Pass). This inventory has also been incorporated into the Australian Landslide Database managed by Geoscience Australia.
" Development of knowledge-based Landslide Susceptibility and Hazard using GIS, with the aid of the afore mentioned GIS-based Landslide Inventory for Wollongong City Council. Whilst developed prior to, this work is in accordance with the recently published AGS March 2007 Landslide Zonation Guidelines.
" Design and construction operations of a network of continuous near real-time landslide field monitoring (CRTM) stations at various landslide sites in the Wollongong Area in collaboration with the Wollongong City Council, the Roads and Traffic Authority and RailCorp, near Geelong (as mentioned below) in Victoria and also in collaboration with Mineral Resources Tasmania at the Taroona landslide.
" Development of continuous Internet Protocol real-time communications between landslide sites and a computer server for the CRTM stations.
" Development of a web-based facility to manage in bound data from continuous real-time monitoring field stations (CRTM), associated databases and real-time display of data via the world wide web PIN protected html address:
" Collaborated with A. S. Miner Geotechnical in the geotechnical investigation of the Dell landslide site at Clifton Springs and in the design and construction of a web-based continuous real-time landslide monitoring station at this site. Then subsequently collaborated with Coffey Geosciences and A. S. Miner Geotechnical in a Risk Assessment of the site for the Geelong City Council.
" Providing supporting geotechnical advice to Coffey Geosciences as part of the RTA Alliance during the Hazard and Risk Assessment of the problematic Lawrence Hargrave Drive between Clifton and Coalcliff, Wollongong during late 2003 - 2004.
" Wollongong City Council  Providing geotechnical advice and review of Development Applications and Construction Certificates and day to day geotechnical advice for Wollongong City Council in place of staff geotechnical engineer on leave. November 2003 - February 2004
" Sought out by Police, State Emergency Services and Wollongong City Council (WCC) during the August 1998 rainfall event to be one of a three man team assessing hazard and risk of current landslide events and to facilitate the development of an effective emergency landslide management strategy

Future Research Topics:

* Site specific quantification of landslide frequency and magnitude
of displacement with the aid of continuous landslide monitoring data
