If it breaks, or shakes, I love it. Precambrian? Awesome! Neogene? Superb! Brittle? Heck yes! Ductile? Any day of the week! In the field? Yesyesyes! In deep ocean core? OMGYes! On seismic? Always. With more geophysics? Yes please! Real rocks? Fantastic! Remotely-sensed data? Give me more! Basement reactivation? Makes the world go round. With Mass transport deposits? Yes please! Education and outreach? It's the only way to share the love.

Structural Geology/Tectonics: I work on structural geology and tectonics in rocks of all ages, from ductile deformation and microstructure in the Precambrian to Quaternary deformation and recent earthquake-generated landslide deposits

Seismic interpretation: much of my work is with seismic data, both shallow (exploration scale) and deep-crustal (20 seconds TWT), both onshore and offshore. I look specifically  for deformation, fault reactivation, inversion, basement control, active faults, and landslide deposits. For younger deformation I am interested in links with present-day and palaeoseismology. I also work with sub-bottom profile data, which can also recorded surface deformation and mass transport deposits.

Seismo-tectonics/neotectonics/geohazards: I investigate links between earthquakes and mass transport deposits in both interplate and intraplate tectonic settings, both onshore and offshore. There are strong links between seismicity, geohazards and landscapes in Western Australia. In the course of this work over many years I have investigated both onshore and offshore seismicity, and deployed seismic monitoring networks in remote areas of NW Western Australia.

Marine Geology: part of my interest in seismicity and tectonics takes me offshore. In recent years I have been part of two scientific expeditions, SO257 and IODP Expedition 386. Expedition SO257, aboard the German vessel RV Sonne, travelled from Darwin to Perth, collecting sediment cores and imaging of shallow crustal deformation. I was part of a geophysics/seismic team that collected a number of new, shallow, multichannel seismic lines across the North West Shelf, as well as also collecting bathymetry and sub-bottom profile data. Our results identified a number of new, young landslide deposits across our work areas, allowing us to document structural processes and links to seismicity. IODP Exp 386, Japan Trench Seismology, collected deep oceanic sediment cores and detailed bathymetric and sub-bottom profile imagery to identify records of past mega-earthquakes in the Japan Trench. As Team Leader Hydroacoustics I work mainly with the remotly-acquired data (bathymetry, sub-bottom profiles) to map the extent of the many mass transport deposits identified in the data, and processes that affected them.

Basement inheritance: It is clear from our large regional interpretations of deep crustal seismic data, that basement reactivation, mainly of Precambrian stuctures,  plays a large role in controlling the locations of active faults in NW Western Australia. We have documented this across the NW Shelf of Australia, linking basement inheritance and reactivation to multiple pulses of shortening and inversion throughout the Phanerozoic.

Tectonics of East Timor: Having started UWA’s geology research program in East Timor in 2003, I have made dozens of trips and spent months in the field in East Timor, conducting field research and training generations of Australian research students and East Timorese undergraduate and postgraduate students. I continue to work with government agencies in supporting their ongoing development efforts.

Planetary geology: I've maintained an interest in planetary geology since my PhD days, and continue to offer student projects, especially interpreting Magellan data on Venus. This incredible dataset still has much to offer in terms of understanding crustal processes on our sister planet.

Teaching Outdoors: I'm passionate about education and outreach, and have developed an award-winning microcredential to encourage teachers to develop multi-disciplinary outdoor learning programs.

As Team Leader for Hydroacoustics for IODP Exp 386, I continue to work on the various datasets acquired during the voyage, and collaborate with the extensive scientific team to identify and interpret palaeoseismicity in the Japan Trench.

The neo- and seismo-tectonics of the northwestern Australia

Anything young on seismic that has breached the surface or is near surface, preferably with some lovely MTDs nearby. Especially if it links with deeper structures.

Tectonic evolution of East Timor
We have been working in East Timor since 2003, looking closely at the structural relationships and re-mapping and re-dating the formations, with a view to constraining and formulating models for the tectonic evolution of this part of Timor Island.   See also the page of my colleague, Dr. David Haig.

Hydroacoustic and seismic data, NWS
I continue to work on and integrate the seismic and other hydroacoustic data from SO257 into our broader NWS databases.
