| 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 Emma Mary Hill | Research interests involve the application of space geodesy to understanding climate change and natural hazards, including measuring sea-level rise, tectonic deformation and melting glaciers using the Global Positioning System (GPS), GRACE gravity satellites and the global tide-gauge network. Future research will particularly focus on the regions of South and Southeast Asia. A particular focus is the development of techniques to combine different geodetic data sets for the purpose of separating the effects of the many different geophysical processes occurring in the Earth system. |
| Assoc Prof Federico Lauro | Dr Lauro has an aptitude matched with a passion, to discover the ways in which microorganisms evolve, adapt and function to drive the ecological processes that are critical for sustaining the health of global marine environments. He has purposefully developed skills in both experimental and computational sciences – in particular, deep-sea microbiology, and the latest “omic” technologies that are essential for deriving a clear and thorough understanding of microbial communities and ecosystem function. Importantly, Lauro has also gained an expert level of proficiency in microbial genomics – this has been achieved through the pursuit of creating bioinformatic tools for analyzing and modelling large datasets, involving a broad range of PERL-programming and implementation of open-source software. Along with his pursuit of marine microbial environments, Lauro is extending his exploration of microbial environments to that of the air microbiome. |
| Assoc Prof Fidel Costa Rodriguez | I'm interested in understanding the formation, transport, and eruption of magmas
(silicate melt, gas and crystals) on the Earth's surface. Main focus are the conditions
(pressure, temperature, volatile contents) at which magmas are stored prior to
eruption, the processes that lead to the erupted magma compositions
(magma mixing, crystallization), the rates and time scales at which these
processes occur, and, finally how all this information relate to volcanic monitoring
data and unrest phenomena. I have expertise and use a large variety of geochemical
(SEM, electron microprobe, SIMS, FTIR, LA-ICP-MS, XRF, INAA), experimental
(high pressure and temperature apparatus for phase equilibria),
and modeling (finite differences for kinetics in solid state) approaches. |
| Dr Grahame John Henderson Oliver | Past Research
After graduating from Sheffield University (1970), I worked in mineral exploration for a year in New Zealand and then undertook PhD research at Otago University on the lower crustal rocks exposed adjacent to the Alpine Fault in Fiordland (1976). There then followed two years of post-doctoral research: Rb-Sr dating Fiordland rocks (Cambridge, UK) and basement geology of the Navan Pb-Zn mine (University College Dublin, Ireland) before taking a Lectureship at St Andrews (1978). During 30 years at St Andrews I researched the sub-greenschist (prehnite-pumpellyite) metamorphism of the British Caledonides, zircon geochronology of the Polish Caledonides (with a sabbatical year of zircon dating in Canada), geodynamics of the Main Central Thrust and Lesser Himalayas; metamorphic core complexes and regional detachments in the Damara Belt, Namibia; the Outer Isles Fault Zone, Outer Hebrides; the Ballantrae Ophiolite, and the geodynamics of Scottish Caledonian granites (including a sabbatical year of zircon dating in Australia with Prof S Wilde). I have been collaborating with Dr J Najman (University of Lancaster) and Dr Ruth Robinson (University of St Andrews) on the type and age of detrital minerals in the Ganges and Irrawaddy river systems and the timing of the Himlayan Orogeny and river capture.

| Prof Kerry Edward Sieh | My principal research interest is earthquake geology, which uses geological layers and landforms to understand the geometries of active faults, the earthquakes they generate, and the crustal structure their movements produce. My early work on the San Andreas fault led to the discovery of how often and how regularly it produces large earthquakes in southern California.
More recently, my students and colleagues and I investigated Taiwan's multitude of active faults and figured out how their earthquakes are creating that mountainous island. We are currently exploring the earthquake geology of Myanmar (Burma). Our principal current research interest is the subductionmegathrust that produced the devastating giant Sumatran earthquakes and Indian Ocean tsunamis of 2004 and 2005. That research suggests that the megathrust is poised to produce yet another giant earthquake in western Sumatra.
I am also now involved in creation of the Earth Observatory of Singapore, which aims to conduct basic and applied research related to earthquake, tsunami, volcanic, and climate hazards. |

| Assoc Prof Lim Teik Thye | Prof Lim's scope of research projects encompasses both practical application of environmental technologies for pollution control and investigation of the process fundamentals. His core areas of research interest focus on application of advanced oxidation processes for water and wastewater treatment, developing novel functional materials for water purification, and developing innovative subsurface remediation technologies. He has over the years developed a range of nanomaterials for treating organic and inorganic micropollutants in surface waters, industrial wastewaters, and groundwater. He has also worked on projects exploring innovative use of industrial wastes for various applications, such as construction, earthwork, and environmental preservation.
His current research projects are as follows:
Novel photocatalysts
This research engineers a novel photocatalyst for enhancing photocatalytic redox processes under solar radiation to remove emerging contaminants in water. It leverages off the complementary strengths among environmental process engineering, materials engineering and advanced materials characterization to develop a new-generation photocatalyst system. The advanced photocatalyst is a composite of nitrogen-doped titania (N-TiO2) supported on the powdered activated carbon (AC), or N-TiO2/AC. The composite have dual functionality, exhibiting high adsorptive properties for a variety of organics and photoactivity under visible light. The synergistic properties of the N-TiO2/AC composite enables its on-site regeneration, producing zero waste stream.
Selective nanoporous adsorbents
The goal is to develop various functional nano-structured materials such as layered double hydroxides (LDHs), zeolites, calcium aluminosilicates and nanoporous carbons to selectively adsorb trace inorganic contaminants, organic contaminants, and biomolecules that are difficult to be sequestrated using conventional adsorbents. The materials, such as LDHs and zeolites, can also function as catalysts to remove recalcitrant contaminants in water and air. Several types of LDHs have been synthesized in our laboratory. The LDHs have been evaluated for sorption of Cr(VI), As(III), As(V), Se(VI), and other oxyanions found in groundwater, surface waters and industrial wastewaters. Removals of up to 99% of certain oxyanions are possible.
Bimetallic zerovalent metal particles
The research group has synthesized nano-scale, bimetallic particles such as Ni/Fe and Pd/Fe for catalytic reductive transformation of halogenated alkanes and haloaromatics. The transformation pathways for these contaminants have been established for different types of synthesized bimetallic particles, through kinetic and mechanistic examinations of the experimental findings. The effects of catalyst content and particle ageing on their reactivities are investigated. Aqueous matrix effect on the transformation kinetics has been also examined in order to understand the possible performance of these reactive particles in industrial wastewater and contaminated groundwater. |
| Assoc Prof Low Bak Kong | Reliability analysis in geotechnical engineering, soil and rock slope stability, ground improvement, rock engineering, and engineering analysis accounting for uncertainty.

| Asst Prof Martin Skote | Prof Skote's areas of expertise are Direct Numerical Simulation, Turbulent Boundary Layer Flow, Separation, Atmospheric Flow, Urban Air Quality, Turbulence Modeling, Plasma Actuator Modeling. His current research works focus on fundamental studies of turbulence aiming at the control of turbulent boundary layers. |
| Assoc Prof Massimo Pica Ciamarra | We are interested in understanding the physics of disordered many-particle systems via statistical mechanics tools and numerical simulations, which is arguably one of the most pressing needs in material science. Such an understanding is crucial to 1) design atomic or polymeric disordered materials with specific mechanical and rheological properties; 2) rationalize natural catastrophic events, such as earthquakes and avalanches; 3) improve the many industrial products and processes handling particulate media, from the food to the pharmaceutical and the electronic industry. The main difficulty is the developing of a theoretical framework connecting the macroscopic and the microscopic scales in the presence of disorder. Some topics of specific interest are:
1. glass transition
2. suspensions of soft deformable particles, e.g. microgels
3. liquid with density anomalies
4. rheological properties of disordered particulate systems, with applications to earthquakes
5. pattern formation in driven particulate systems, e.g. segregation
6. transport properties in disordered media |
| Asst Prof Mikinori Kuwata | His research goal is to understand chemical processes in the atmosphere, those are important for both global and regional environments.
His specific research interests include:
(1) Haze originated from forest burning
Including Singapore, many countries in Southeast Asia are experiencing haze originated from forest burning. Those haze plumes have significant adverse effects on regional environments such as human health and visibility. Chemical reactions in the atmosphere form compounds responsible for those phenomena. He is trying to understand emission and formation mechanisms of those compounds by atmospheric observation and laboratory experiments.
(2) Atmospheric chemistry in tropical region
Tropical rainforest is a globally important source of atmospheric trace gas species. Chemical reactions of those species form some key materials for the global climate such as nuclei of cloud droplets. Human activities in tropical areas, including Southeast Asia, are changing those naturally occurring chemistry. For instance, emission of trace gas species from plantation is significantly different from original tropical rainforests, altering chemistry in the atmosphere. Enhanced human activity in the tropical region provide a higher chance for anthropogenic species to react with biogenic origin compounds, perturbing original chemistry in the atmosphere. He is interested in quantifying how interaction between human activities and tropical environment changes chemistry in the atmosphere, and how the perturbation affects the global climate. |
| Dr Natasha Bhatia | Dr Bhatia's research interests are centered around understanding the interactions between environmental economics and the marine environment. Through the identification and valuation of ecosystem services, policy and management decisions can be made in a way which promotes the sustainable use of the environment, something which impacts us all. Specific projects have previously included socio-economic valuation of Special Areas of Conservation along the east coast of England; Non-market modelling of the changing value of coastal ecosystem services in the wake of the 2013 UK storm surge; the FP7 project ‘VECTORS’ which investigated the drivers, pressures and vectors of change in marine life and its impact on marine economic sectors; and the EU project ‘DEVOTES’ which aimed to develop innovative tools for understanding marine biodiversity and the assessment of good environmental status, as well as creating conceptual models for the effects these pressures have on society. |

| Asst Prof Patrick Martin | My research interest focus on the cycling of carbon, nitrogen, and phosphorus in the marine environment. The cycling of these elements is an essential part of the global climate system, and is also critical in supporting healthy marine ecosystems. My research concentrates on biogeochemical processes in plankton communities (microscopic algae, bacteria, zooplankton), but spans a range of temporal and spatial scales, with work ranging from laboratory cultures to ocean basin-scale transects.
Specific topics concern how plankton communities sequester carbon from the atmosphere in the ocean, how physiological responses by marine plankton to nutrient starvation affect the cycling of phosphorus in the sea (which is critical for supporting continued productivity of marine ecosystems), and how land-derived dissolved organic matter is processed in coastal waters. |

| Prof Satish Singh | Professor Satish Singh has a very broad research interest in geophysics, covering theoretical developments, design of innovative field experiments, analysis and interpretation of a variety of geophysical and geological data using advanced techniques and has made fundamental contribution in several disciples of Earth Sciences. Some of the research achievements below highlights his research interests:
Modelling and Inversion: Singh is a world leader in modelling and inversion of seismic data and has established one of the most productive research groups in Europe. He was the first to recognise the importance of jointly inverting seismic reflection and refraction data and developed 2D and 3D tomographic inversion techniques. Long before waveform inversion became one of the main areas of research, he developed 2D full elastic inversion and applied to long offset streamer data, to ocean bottom cable data, and time lapse seismic and included electromagnetic data in a joint inversion.
Mid-Ocean Ridges. Singh started working on Mid-Ocean Ridges in late nineties when he first applied seismic full waveform inversion to seismic data from the East Pacific Rise and showed that axial magma chambers are segmented along the ridge axis between 2-4 km pure melt lenses at 15-20 km mush zones, and published his seminal paper in Nature in 1998. In 1997, in collaboration with colleagues from Scripps Institution of Oceanography, he led the world's first 3D seismic reflection-refraction seismic experiment at the northern East Pacific Rise and discovered the widest melt lens beneath 9ºN overlapping spreading centre and imaged the Moho beneath the axial magma chamber and published two papers in Nature (2000, 2006). In 2005, he led another 3D seismic experiment at the Mid-Atlantic Ridge, and discovered axial magma chamber at a slow spreading ridge for the first time (Nature, 2006).
Subduction Zones. After the 2004 great Sumatra Andaman earthquake, Singh launched an ambitious research program, which was not just funded by government funding agencies, but also by industry that provided their best technology to image the faults and rupture zone. Using these exceptional technologies, he was able image the subducting oceanic crust (top and Moho) down to 60 km depth. He showed that the down-going subducting plate breaks, bends and unbends as it subducts, possibly rupturing a part of the oceanic plate during great earthquakes, such as Sumatra 2004 (Nature Geoscience, 2008). He has imaged the deepest subducted seamount (30-40 km) beneath the Sumatra forearc continental mantle and suggested that subduction of seamounts can lead to a weak coupling, can act as barrier for rupture propagation, and hence reduce the maximum size of earthquakes (Nature Geoscience, 2011). Using these high-resolution seismic data, Singh suggested that large tsunamis during the 2004 and 2010 earthquakes were due to frontal rupturing, which was supposed to be aseismic; same thing happened during the 2011 Tohoku earthquake.
Gas Hydrate: Singh made a major impact on the study of gas hydrates when he inverted seismic data from the Cascadia margin and showed that bottom simulating reflections (gas hydrates) are mainly due to a small amount of free gas and the amount of hydrate above is also very small and therefore the total amount of methane present in gas hydrate stability zone along the continental margins would be an order of magnitude smaller than predicted previously and hence its effect on its energy potential and the global warming would be much small (Science, 1993).
Singh has also worked on the inner core suggesting that upper part of the inner core is partially molten (Sience, 2000). Now he wants to study the whole of the lithosphere, particularly the lithosphere-asthenosphere boundary and is organising series of marine experiments across Atlantic Ocean. |

| Asst Prof Susanna Jenkins | My research interests lie in volcanic hazard, vulnerability and risk assessment for the purpose of disaster risk reduction. I achieve this through the use of numerical models, field studies and the statistical interrogation of large datasets.
Recent research has focussed on investigating techniques and frameworks for probabilistic hazard and risk assessment. This includes the development of large-scale multi-source ash dispersal models that calculate the total ash hazard at a site, rather than from a volcano (used for the 2015 UN-ISDR Global Assessment Report), and the quantification of likely hazards and physical impacts arising from volcanic eruptions, through pre- and post-eruption field studies and numerical modelling.
Research areas include Indonesia, Philippines, Italy, Iceland, Cape Verde and the Lesser Antilles. |
| Asst Prof Sylvain Barbot | The goal of my research is to develop a physics-based model of the earthquake cycle to assess the full range of seismic behavior that can be expected across a plate boundary.
I use remote sensing (synthetic aperture radar, GPS, optical photographs, gravity) and seismological data to investigate the mechanics the lithosphere and fault slip. These measurements can be used to constrain models of rupture and lithosphere dynamics, which include faulting, but also more distributed deformation, such as poroelastic and viscoelastic flow. An important goal of my research is to reconcile long-term (regional tectonics) and short-term (earthquake dynamics) observations and improve our capacity to predict some aspect of the earthquake cycle. |
| Assoc Prof Tan Soon Keat | Dr Tan's research interests include application of geographical information system (GIS) in water resources, numerical simulation of flow for hydraulics and coastal engineering applications. His current research projects include hydrodynamic consideration of mega underwater structures and application of wetland technologies in the removal of pharmaceutical products from wastewater streams.
Dr Tan specilaises in urban water management, rainfall-runoff modeling as well as water quality modeling, flooding, drainage, urban response, climate change and future scenarios analysis. Managing surface water in terms of quantitative distribution, storage and transport, removal of water-borne contaminant, particularly trace quantity of drugs and pharmaceutical products from waste-water streams are challenges in the management of water resources, and in particular, supply of raw water in the face of climate change and rapid urbanisation. A viable and feasible solution is to employ wetland technology as a means to remove contaminants and management of peak runoff. Under the supervision of Dr Tan, a research team is carrying out a series of constructed wetlands experiments with raw water spiked with selected contaminants. The research work has produced meaningful results and highly cited publications since its inception in 2009.
Currently Dr Tan is leading research work on strategic development of coastal, urban scape and water resources, in response to climate change as well as developmental scenarios. |
| Assoc Prof Tan Soon Yim | Prof Soon Yim TAN's areas of expertise are electromagnetic scattering and diffraction theory, localization methodology and propagation models for wireless communication systems and sensor networks, and non-invasive cancer detection. His current research works focus on non line-of sight localization methodology for mobile communications and sensor networks, Microwave breast cancer detection and magnetic therapeutic. |

| Prof Timothy John White | Tim White has thirty years of experience in the design and demonstration of advanced materials for environmental, superconducting, ionic conductivity and hydrogen storage applications. His particular interests lie in tailoring ceramics at the atomic scale to develop or enhance particular properties. These studies have been supported and facilitated through the use of advanced characterization methods, including atomic resolution electron microscopy, crystal refinement using X-ray and neutron diffraction, and synchrotron-based surface analysis for the investigation of chemical states and molecular environments. He is author or co-author of over 200 publications, 4 conference proceedings, 3 patents and confidential reports to industry.
In 2006, he introduced a suite of teaching modules for materials scientists called On-line Micro- and Nano-characterisation Instruction (OMNI). These courses were extended by the Australian Learning and Teaching Council to create MyScope, a national curriculum in microscopy and imaging. For three years (2007-2009), he ran the first totally on-line course at NTU called Symmetry and Crystals. Together with a team from Centre for Excellence in Learning and Teaching (CELT), he is delivering the Coursera MOOC Beauty, Form and Function: An Exploration of Symmetry. |
