Asst 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 Peter 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 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.

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 Law Wing-Keung, Adrian	Research in environmental fluid mechanics with special emphasis on wastewater disposal and impact, environmental hydraulics in wastewater treatment processes, pollutant transport in coastal environment, and advanced laser imaging techniques for measurements.
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.

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.
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.

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 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 and has developed the catchment – drainage GIS map of NTU campus. The GIS map is designed to facilitate rainfall-runoff modeling as well as water quality modeling. While rainfall-runoff modelling is generally well-established, water quality modeling is not, especially in the estimate of the source concentration of the pollutants. Current research focus in the community is in the establishment of the total nitrogen (TN) and total phosphorous (TP) in rainwater runoff. The difficulty lies in the fact that TN and TP varies with time, space as well as the intensity of rainfall. Dr Tan has a PhD project on TN and TP as contaminant in rainwater runoff. Removal of water-borne contaminant, particularly trace quantity of drugs and pharmaceutical products from waste-water streams is a challenge in the management of water resources, and in particular, raw water for water supply. A viable and feasible solution is to employ wetland technology as a means to remove these contaminants. 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 since its inception in 2009. Currently Dr Tan is leading a research team to conduct research on the various hydrodynamics considerations for a mega underwater structure, looking at the effects of flow, wave and environmental loads on a single or group of surface protruding structures. The research team comprises 10 research fellows. The challenge of the project is that the structure is to be founded on the seabed, with living space on the seabed, or supported on legs or semi-submersible, and the columns also support a deck space above the water, making full use of the 3-dimensional space. The structure has to be of mega-size to make it economically viable. As such, the environmental loads, impact of flow and waves takes on a different dimension compared to a land-based structure or oil platforms. Of particular significance is the possibility of vortex-induced-vibrations, as well as trapping or building up of waves within the group of structures. Later research work includes selection of potential site for the construction of a pilot structure as well as the effects of such structure on seabed sedimentation, ecology as well as its impact on the environment.
