|Assoc Prof Adam Douglas Switzer||Adam Switzers main research interest lies in using coastal stratigraphy to define the recurrence interval of catastrophic marine inundation events (tsunami or large storms).
His most significant contributions to the field include:
* the first study of modern storm deposits from the Australian southeast coast;
* the recognition that immature heavy mineral suites in coastal sandsheets may indicate tsunami deposition rather than storm deposition in coastal settings;
* the recognition of an erosional signature of large scale washover of coastal dunes using Ground Penetrating Radar;
* initial evaluation of the sedimentary processes associated with the 2004 Indian Ocean tsunami on the southeast coast of India
a definitive review and re-analysis of large boulder accumulations in coastal settings on the southeast Australian coast.
|Prof Benjamin P. Horton||My research concerns sea-level and environmental change. I aim to understand and integrate the external and internal mechanisms that have determined sea-level changes in the past, and which will shape such changes in the future. Fundamental to this aim is bridging the gap between short-term instrumental records and long-term geological reconstructions and geophysical predictions. To this end, I have developed, tested and validated a new methodological approach that uses microfossils to quantitatively reconstruct former sea levels. By applying this approach and simultaneously developing cross-disciplinary collaborations, my work has led to new knowledge, in particular predictive models of relative sea-level, and has impacted upon important societal and economic coastal problems.
|Asst Prof Benoit Taisne||Benoit Taisne’s current research focuses on the early anticipation of the style and size of volcanic eruptions. He uses new tomographic methods (muon telescopes) to shed light on two crucial parts of the volcanic system that have so far remained elusive for volcanologists and hazard managers, and which are key inputs for ash dispersal models:
- The structure (i.e. density distribution) and geometry of the volcanic conduit,
- The characteristics of ash columns.
Results from the muon tomography experiments will be complemented by more traditional data and methods from different disciplines like geophysics (seismologic studies), geodesy (GPS studies), and geochemistry (petrology and gas chemistry). All these data will be jointly inverted in near real-time with physics-based models of magma migration to get quantitative values for key physical parameters controlling the eruption style, and hence anticipate the style and size of eruptions to come.
His main research interests are:
- Magma migration
- Eruption dynamic
- Development of realtime monitoring technics
- Numerical simulation
- Laboratory experiments in fluids dynamics
|Asst Prof Caroline Bouvet De Maisonneuve||The development of increasingly precise geophysical monitoring tools has led to progress in the field of eruption forecasting, but predicting the size and vigor of an eruption remains a major challenge in the assessment of risks. The vast majority of active volcanoes display wide ranges in eruption styles over long and short time scales, from effusive lava flows or dome growth to explosive Strombolian, Vulcanian, or Plinian eruptions. My long term goals are to shed light on the combinations of processes and physical parameters that govern the magnitudes and styles of eruptions, and to enhance our ability to interpret geophysical and geodetic monitoring signals in terms of magmatic processes.
My main research interests, therefore, focus on:
What processes control the magnitude and style of a given eruption?
How and why do these controlling factors change from one eruptive center to the next?
Why does the magnitude and style vary from eruption to eruption at a same volcano?
In addition, the fact of addressing these questions may also bring elements of response to more petrology-based problems such as: How to reconcile the plutonic and volcanic record? How and where do magmas differentiate (e.g. assimilation vs. fractional crystallization)? How do the transport, accumulation, and differentiation of magma affect the formation of continental crust?

|Assoc Prof Danne Ojeda Hernandez||Her current research is devoted to the disciplinary redefinitions of Graphic Design and its implications in contemporary visual culture. It analyses antithetical aspects within the evolution of graphic design, like its communicative and allegoric nature, autonomy and social commitment, and expressivity and new media standards. The theoretical basis of this research includes binary concepts like natural/artificial, original/copy, public/private, and physical/virtual. The research is methodologically structured upon close readings of a variety of visual objects from the perspective of graphic design. These objects are discusses in connection with different sorts of conceptual platforms, like manifestos, (un)realized projects, curatorial proposals and critical reviews among others sources within today's dominant orientations in graphic design.
Moreover, her areas of interest can be summarized as follow: Issues in Visual Communication/Contemporary Design, Design Theory, Design and Science and Art and Design relations. Her areas of specializations regarding professional practice are mainly editorial and exhibition design.
