Career Summary

Biography

Environmental pollutants are pervasive throughout the human food chain. One of the major challenges in environmental chemistry is determining contaminants in situ rapidly and reliably prior to significant changes may occur. Determining chemicals of interest in soil, water, food or organism tissues in situ has the major advantage of minimizing chemical transformations that may occur with transportation to laboratories for measurement.

My research interest lies is coupling chemometric computational methodologies to environmental processes and problems. These include rapid determination of contaminants in food stuffs, coupling of erosion processes with in situ measurements and also applying advanced analytical measurements to ecotoxicological processes. This includes high resolution mapping of contaminants in a range of environmental media.

Following my PhD graduation, I continued my research direction as a full-time postdoctoral researcher. From 2011 to present time, I have worked full-time as a postdoctoral researcher at University of South Australia and the University of Newcastle.

My research contributions and interests include:

  1. Computational methodologies and chemometrics
    • My work developed and patented a methodological system for automatic analysis of Fourier Transform Infrared spectral data to simultaneously determine six BTEX components (benzene, toluene, ethylbenzene and three different xylenes) in mixed vapour samples. It became evident that organic compounds can be comprehensively and simultaneously determined using FTIR spectral data located in the fingerprint region;

  • Application of a genetic algorithm (GA) to modify one of the most popular Independent Component Analysis (ICA) methods, the fast fixed-point algorithm for ICA (fastICA), to avoid the local maxima problem commonly observed with fastICA. This patented method, geneticICA, can be used as a data pre-processing method to improve the accuracy of prediction of BPNNs;

  • Furthermore, in order to simplify the recalibration procedures of ion selective electrode array for practical utilities, my work developed and patented mathematical models to describe the characteristics of an ion selective electrode (ISE) array’s response. By using the models with measuring only a very few standard solutions, the ISE array can be automatically recalibrated. These methods increase the simplicity of measurement of multiple ions simultaneously with ISEs.

  1. Ecotoxicological modelling
    • My work coupled the factorial design experiment with artificial neural networks and genetic algorithms to develop a model for predicting the interactive toxicological effects using a soil microalga. The chemicals included in the mixtures were two polyaromatic hydrocarbons (PAHs), phenanthrene and benzo[a]pyrene, and two heavy metals (HMs), cadmium and lead. Three bio-chemicals implicated in oxidative stress, viz., malondialdehyde (a measure for lipid peroxidation, LPO), catalase activity and proline accumulation were used as the toxicity criteria;

  • My work applied computational methodologies to optimize the parameters of a terrestrial biotic ligand-like model (BLM) including carbonate and phosphate. Estimated effective concentrations from the BLM-like parametrization were strongly correlated to measured arsenate values in pore-water; this approach has also been applied to copper, lead and zinc.

  1. Complementary chemometric and environmental modelling

  • Combining chemometric techniques to environmental and ecological processes provide detailed in situ information on chemistry and environmental processes. I have developed erosion models to evaluate the fate and transport of a range of environmental contaminants based on the landscape and soil properties.

  1. Environmental monitoring

Development of on-line monitoring sensor array’s such as chemical sensors and FTIR. The research involves applying computational and mathematical methods to the design and selection of optimal procedures and experiments to maximise information obtained from analysis of chemical data. I have developed on-line monitoring integrated with chemometric methods, including:

  • Development of both combined sensor probes with capacity to monitor multiple contaminants in the field;
  • Development of software tools and smart phone access for remote monitoring of pollutants in the environment;

© 2018 by Taylor & Francis Group, LLC. Historically, mining of metalliferous ore bodies was a relatively dispersed activity, with numerous small mines occurring throughout many western countries including the United States, the United Kingdom, and Australia (Soucek et al. 2000, Grant et al. 2002, Mayes et al. 2009). Many metalliferous mine sites began operation in the late eighteenth and early nineteenth centuries and were abandoned in most instances before the environmental movement in Western countries. As such, there was very little recognition of the potential impacts caused by the dispersal of metal toxicants such as arsenic (As), cadmium (Cd), copper (Cu), lead (Pb), and zinc (Zn) into the surrounding environments from these sites. Many of these contaminants are cariogenic in humans (e.g., As), cause a range of human health-related impacts (Pb, Cd), and are toxic to ecological receptors in nearby streams and surrounding terrestrial environments (Cu, Zn, Mn, Ni). As a result of the lack of regard for potential impacts, much of the mining waste was discarded carelessly throughout mining sites, and in some cases, directly into nearby watercourses

© 2017 Elsevier Ltd Arsenic (As) and zinc (Zn) are common co-contaminants in mining impacted soils. Their interaction on solubility and toxicity when present concurrently is not well understood in natural systems. The aim of this study was to observe their interaction in solubility (soil-solution), bioaccumulation (shoot uptake) and toxicity to cucumber (Cucumis sativa L) conducting 4 weeks pot study in 5 different soils spiked with As (0, 2, 4, 8 to 1024 mg kg-1) individually and with Zn at two phytotoxic doses. The As pore-water concentration was significantly reduced (df = 289, Adjusted R2 = 0.84, p < 0.01) in the presence of Zn in the whole dataset, whereas Zn and Zn2+ activity in pore-water was reduced significantly only in the two alkaline soils. This outcome may be due to adsorption/surface precipitation or tertiary bridging complexation. No homogenous precipitation of zinc arsenate could be established using electron microscopy, XRD or even equilibrium calculations. For bioaccumulation phase, no significant effect of Zn on As uptake was observed except acidic MG soil whereas, Zn uptake was significantly reduced (p < 0.05) by As in whole dataset. However, an additive response was observed mostly except acidic MG soil. The synergistic response (more than additive) was predominant in this soil for a wide range of inhibition concentration (0¿80%) at both Zn EC10 and EC50 levels. Since additive response is mostly considered in risk assessment for mixtures, precautions should be implemented for assessment of toxicity for As-Zn mixture in acidic soil due to their synergistic response in some soils.

© 2015 Elsevier B.V. Work reported in this manuscript takes into consideration the possible use of NH3 gas by terrorists and the potential for an effective and rapid removal of such toxic substance from air using a modified clay material. In this study, a series of clay/polymer composites were synthesised for ammonia gas (NH3) adsorption. The adsorbents were prepared by polymerisation of acrylic acid with N,N'-methylenebisacrylamide (MBA) as cross-linker in the presence of a large amount of highly dispersed clay nanoparticles, followed by interaction with copper ions (Cu2+). Two kinds of clays were used. One was an acid-treated bentonite that had a specific surface area (SSA) of 395 m2/g and the other was natural palygorskite with a SSA of 87 m2/g. The materials were characterised by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), nitrogen adsorption-desorption and Fourier transform infrared spectroscopy (FTIR). The materials' ability to remove NH3 was investigated using NH3 breakthrough dynamic test while the strength of NH3 retention was characterised by Thermogravimetric Analysis (TGA) coupled with FTIR. The results indicate that clay/poly-acrylic acid composites are highly efficient adsorbents of NH3 after binding with Cu2+. Trapping NH3 on such adsorbents can lead to colour change and this makes it possible to predict the lifetime of the adsorption bed visually. In addition, the result of NH3 release from the material following adsorption showed that majority of the adsorbed NH3 desorbed at temperature above 180°C. The clay/polymer composites can potentially be used in air filters. They may provide an effective and cheap way for removing NH3 from contaminated air.

© 2015 Elsevier B.V. This study introduced a patented novel methodological system for automatically analysis of Fourier Transform Infrared Spectrometer (FTIR) spectrum data located at 'fingerprint' region (wavenumber 670-800 cm-1), to simultaneously determinate multiple petroleum hydrocarbons (PHs) in real mixture samples. This system includes: an object oriented baseline correction; Band decomposition (curve fitting) method with mathematical optimization; and Artificial Neural Network (ANN) for determination, which is suitable for the characteristics of this IR regions, where the spectra are normally with low signal to noise ratio and high density of peaks. BTEX components are potentially lethal carcinogens and contained in many petroleum products. As a case study, six BTEX components were determinate automatically and simultaneously in mixture vapor samples. The robustness of the BTEX determination was validated using real petroleum samples, and the prediction results were compared with gas chromatography-mass spectrometry (GC-MS).

Analyte ion detection methods and tools$493,105

Controlling the quality of irrigation water is important for successfully promoting crop and plant growth and can be monitored in situ using an ion-selective electrode (ISE) array with suitable data processing algorithms. CRC CARE has developed a novel technique (probeCARE™) for the real-time measurement of metal ions in solution using Ion Selective Electrode (ISE) Arrays. The outfit of probeCARE™ is demonstrated in Fig.1. The technique includes software that has been developed to allow real-time measurement of a multitude of free ions simultaneously in solution. probeCARE™ allows common ions such as sodium, potassium and calcium to be measured in complex solute matrices, even in coloured solutions. This is of value to agricultural irrigators and for monitoring water quality in lakes and streams. Existing techniques utilise laboratory equipment whose size and weight render them inappropriate for in-field measurements. Consequently, process time and equipment costs can be prohibitive. probeCARE™ supports cost-effective, in situ, real-time monitoring, together with improved management strategies for cropping, improved fertigation (applying fertilisers or other soil amendments through an irrigation system), effective use of recycled water, and monitoring for possible pollutants to ensure EPA standards are achieved. probeCARE™ is being developed with internet connectivity to truly support remote sensing and continuous monitoring of critical resources.

I am now learning new skills in supervising research colleagues and building a collaborative relationship with Dr Cheng. She supports my research while I help to develop her own experience.&amp;nbsp;
