| Prof Benjamin P. Horton | 200 million people worldwide live along coastlines less than 5 meters above sea level. By the end of the 21st century this figure is estimated to increase to 400 to 500 million. These low-lying coastal regions vulnerable to changes in sea level brought about by climate change, storms or earthquakes. My research uncovers fundamental knowledge about how sea level has changed in the past and how it may change in the future. My findings therefore impact upon important ethical, social, economic and political problems specifically facing such coastal regions.
The Intergovernmental Panel on Climate Change (IPCC) re-emphasized the importance of sea level as a barometer of climate and drew attention to the potentially devastating consequences of future climate change. The IPCC highlighted the uncertainty with which the driving mechanisms of recent sea-level change are understood and the disconnect between long-term geological and recent observational trends. My research directly addresses the rates and geographic variability of sea-level change, which was highlighted at the top of the list of the eight priority science questions in the “Sea Change: 2015-2025 Decadal Survey of Ocean Sciences” report. The study of sea-level change was subsequently recommended as Strategic Research Priority I in “A Strategic Vision for NSF Investments in Antarctic and Southern Ocean Research”.
An incomplete understanding of the earthquake and tsunami hazards associated with the Sunda and Japan subduction zones contributed to the devastating societal impacts of the 2004 Indian Ocean and 2011 Tohoku events. Instrumental records of previous earthquakes and tsunamis proved too short to estimate the potential magnitude and recurrence interval of such great events that recur centuries to millennia apart. My earthquake and tsunami records on centennial and millennial temporal scales are necessary to understanding long-term subduction zone behavior and the occurrences of large, but infrequent events.
Tropical Cyclones and their associated storm surges are among the most destructive natural disasters to impact coastal regions. The severity and frequency of coastal floods is increasing (and will worsen in most locations over the 21st century. But the short timescale and narrow range of 20th century forcing captured by the instrumental record may not address important mechanisms underlying the dramatic changes expected in the late 21st century. My reconstructions of paleo storms reveal spatial and temporal variability of tropical cyclone activity and provided insight into their relationship with global climatic changes.
I have forged very strong international collaborations with developed and developing countries (e.g., Indonesia, Iran, Malaysia, Philippines, Vanuatu and Thailand). My research involves partnerships between fellows, graduate and undergraduate students of geology, archaeology, geophysics, oceanography, fluvial hydrology, statistics and atmospheric science. My research portfolio extends beyond the collection and interpretation of sea-level data to include topics as diverse as: development of Gaussian process models for the statistical analyses of paleoclimate data; the socio-economic impact of the 2004 Indian Ocean tsunami; the application of diatom analysis in forensic science; 20th century inter-decadal variability in temperature and precipitation; and the timing and location of emerging civilizations in relation to the productivity of coastal margins. I have thus assembled multinational, interdisciplinary research teams. This has enriched my own thinking and that of my postdoctoral scientists and graduate and undergraduate students. I am/have been supervisor to 22 students to the degree of PhD and 11 postdoctoral scientists. |
| Assoc 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? |

Brief summaries of my research projects are listed below.
Catalytic advanced oxidation processes (AOPs)
I have 15 years of research track records in redox technologies for surface water, wastewater and groundwater treatment. For the oxidation technologies, my research activities cover sulfate-radical based advanced oxidation process or SR-AOP (homogeneous and heterogeneous), UV-based AOP (homogeneous and heterogeneous), Fenton processes (heterogeneous), photocatalysis (heterogeneous), electrochemical oxidation, and sonochemical oxidation, and hybrid AOPs. On SR-AOP, my group has made significant contribution to the scientific community in terms of advancing the understanding of the mechanisms of the heterogeneous SR-AOP with metal oxides (monometallic oxide and bimetallic oxides) and carbonaceous materials as catalysts to activate peroxymonosulfate (PMS) and peroxydisulfate (PDS). We have discussed our works in our numerous scientific papers and 3 critical reviews in the top journals. Specifically, we have provided insights into the radical and non-radical reaction pathways associated with transformation and mineralization of a wide range of organic emerging micropollutants such as antibiotics, cytostatic drugs, bisphenol A and industrial chemicals. On the homogeneous SR-AOP, our group is among the leading contributor to post-formation mitigation strategy for controlling iodinated disinfection by-products such as iodinated trihalomethanes and iodoacids in RO water. Our group also developed composite catalytic materials which comprise mixed metal oxides, bimetallic oxides, and catalyst-nanocarbon composites that exhibit multifunctional properties such as combined catalysis, adsorption-promoted catalysis, “switchable” catalysis, etc. Our iron-based catalytic composites can function as Fenton catalyst, photo-Fenton catalyst and photocatalyst, such that their applications can be switched over the day/night cycle. When irradiated with sunlight, they trigger sunlight-driven photocatalytic redox degradation of organic pollutants without any chemical addition. The materials can be recovered from the treated water using magnet. We have also developed a hybrid TiO2-activated carbon composites, which can be used as solar-driven photocatalyst or solar-regenerable adsorbent. This invention has been approved for PCT filing as a recognition of our intellectual property.
Catalytic ceramic membrane for removing recalcitrant organics
Over the last 10 years, my group has advanced the research of coupling catalytic oxidation and membrane separation process. The synergistic processes were enabled through our catalytic ceramic membrane research. We developed three types of such hybrid membranes: (1) photocatalytic membrane, (2) catalytic sulfate-radical oxidation membrane, and (3) catalytic ozonation ceramic membrane. One of our inventions, Ag-decorated photocatalytic TiO2-coated alumina membrane, has three functionalities: antibacterial and antibiofouling property, photocatalytic activity, and separation function with membrane pore sizes down to 4 nm.

| Asst Prof Marek Mutwil | Dr. Marek Mutwil and his research group combine computational and experimental biology to obtain a genome-wide understanding of gene function in plants. Despite decades of intensive research, only ~15% of genes of the most popular model plant Arabidopsis thaliana have been functionally characterized. To remedy this paucity of functional information, which prevents us from tailoring plants to our needs, the group produces large-scale transcriptomic (in form of RNA sequencing) and protein-protein interaction (PPI) data with the aim to build gene co-function networks. These networks can reveal genes that operate together in the same metabolic pathway, protein complex or regulatory circuit which makes them powerful tools to understand how gene products work together in the cell. The group uses gene co-function networks to answer three questions:
1) What are the functions of plant genes? To generate cutting edge gene function predictions we utilize our own and publicly available large-scale biological data, together with state-of-the-art ensemble prediction algorithms. We make these predictions publicly available with our popular online databases, such as GeneCAT and PlaNet.
2) How are biological networks evolving? Biological features (e.g. secondary metabolites or disease resistance) are encoded by polygenic gene modules, which often cannot be identified by genomics. To uncover them, we use a massively multiplexed protein-protein interaction assay which allows rapid elucidation of genome-wide PPI networks. By constructing and comparing networks of green algae, mosses, vascular-, seed- and flowering plants, we will gain a systems-level, kingdom-wide understanding of when these modules appear and how they change in plant evolution.
3) Which gene modules biosynthesize high-value compounds found in plants? Co-function networks based on RNA sequencing data are a proven tool to identify genes involved in biosynthesis of plant secondary metabolites. The group will focus on elucidating module-metabolite relationships with a special focus on plants of importance to Singapore and the bioprospecting of the rainforest. The functions of the elucidated modules, i.e. production of the secondary metabolites, will be tested by expression in heterologous systems, such as bacteria and/or yeast. |
| 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 |
| 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 interests 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.
The main focus of my research is to understand how land-derived organic carbon is processed biogeochemically at sea. South-East Asia's coastal peatlands are a globally significant source of dissolved organic matter to the ocean, but we do not understand well what happens to this organic matter at sea, and what the environmental consequences of this input are. Using a combination of in-situ observations, laboratory experiments, and remote sensing, we are trying to understand better how extensively this organic matter is degraded by microbial and photochemical processes, and how its presence influences light availability in coastal waters. We are also developing methods to better quantify land-derived organic matter in the sea both in the present (using optical spectroscopy and stable isotopes), and in the past (using palaeoceanographic reconstructions from coral cores).
Furthermore, I am interested in nutrient cycling processes in tropical coastal waters. Using time-series measurements, we are trying to understand how the rates of coral-associated nitrogen fixation are controlled by environmental conditions, and how the cycling rates and bioavailability of dissolved organic nitrogen and phosphorus on coral reefs are controlled. Nitrogen fixation is a potentially important process that contributes new nitrogen to coral reef environments, while the cycling of organic nitrogen and phosphorus is essential for maintaining productivity in nutrient-poor waters. |
| Asst Prof Perrine Hamel | Perrine’s research focuses on the services provided by natural infrastructure in urban and rural environments, with a particular interest in hydrologic services. She has extensive experience in urban hydrologic modelling and has led the development of several ecosystem services models that support management decisions, now incorporated into the InVEST (integrated valuation of ecosystem services and tradeoffs) software. She has conducted natural capital assessments in partnership with environmental NGOs and public and private actors around the world, most recently in Latin America and Southeast Asia. Her research on Southeast Asian cities focuses on three broad themes: i) natural infrastructure for integrated urban water management, ii) climate vulnerability and urban resilience; and iii) incorporation of ecosystem-based management approaches into urban planning. |
| Prof Redfern Simon Anthony Turner | Professor Redfern's work explores how minerals control and reflect Earth processes and he has worked in collaboration with a wide variety of Earth and environmental scientists, from climate scientists to volcanologists to palaeontologist to seismologists and even exoplanetary “geo”scientists. In all cases he is interested in how insights into nanometre scale features provide understanding of global processes. His work has extended to using insights from nature to develop new materials in the context of materials design and engineering.
His research interests focus on the physical and chemical properties of minerals and associated fluids in planetary interiors. He uses experimental and computational methods to understand the role of minerals in Earth and planetary processes at extreme pressures and temperatures. I has published more than 270 peer-reviewed papers in the scientific literature (H-index 46 [ISI], 54 [Google Scholar]), in internationally leading journals including Nature, Science, Physical Review Letters, Advanced Materials, Earth and Planetary Sciences Letters, JACS, Applied Physics Letters, and GRL. His research is highly inter-disciplinary and he has as many papers in the materials physics/chemistry literature as in geosciences.
Professor Redfern pioneered the development of combined high-pressure high-temperature methods for the study of materials and minerals by neutron scattering and was at the vanguard of researchers using neutron methods in Earth and planetary sciences, and built new facilities at Rutherford Appleton Laboratory (UK) for the wider user community, including the first high-temperature high-pressure Paris-Edinburgh Cell for deployment at neutron sources, now used worldwide. From 2003 to 2006 I was Chair of the working group that designed and implemented the Extreme Conditions Beam Line (I15) of the Diamond Light Source synchrotron.
He has edited several thematic sets of papers resulting from international scientific meetings that he convened, including a volume of Reviews in Mineralogy (Mineralogical Society of America) on "Transformation Processes in Minerals", his primary area of expertise. I have held several competitive UK research grants (total funding of more than £25m) and has led collaborations with a strong group of postdoctoral fellows and research students. He has supervised over 30 PhD students in Cambridge, and acted as postdoctoral mentor and advisor to more than 20 postdoctoral researchers, most of whom have gone on to permanent academic, business or governmental science positions. |

| Dr Sylvain Rigaud | Micropaleontology
Carbonate Sedimentology
Macroevolution
Biostratigraphy
I am comparing fossil and sedimentological archives. Convinced that the co-evolution of life and rocks through time will help resolving major questions about life inner workings and past climatic, environmental and oceanographic changes, I intend to develop innovative scientific projects, bridging disciplines, on various aspects of paleontology and sedimentology, with a special focus on the foraminiferal evolution over the Phanerozoic. The scientific questions I would like to address are:
• When and why did major foraminiferal radiations and extinctions occur?
• What controls the spatial and temporal distribution of foraminifers?
• How do foraminiferal tests reflect the biological and genetic complexity?
I therefore focus my research on questioning, refining and expanding our current knowledge on the taxonomy, evolution, phylogeny, ecology, biology, and geographic and stratigraphic distribution of foraminifers through time and space, with the final objective of constraining controls and mechanisms involved in life development and evolution and anticipating future impacts on life and climate. |
| 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. |

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. |
