Research Interests

Advanced noise control material and structure:
The novel soundproof material was prepared by similar ionic polymer structure design and the weighted sound reduction was 24dB with 1mm thickness. Based on the novel soundproof material, a new noise control structure was designed and applied to the highway noise control engineering in the shape of the noise barrier. By realistic measurement, the transmission loss of the barrier can reach 12dB with 6m height.

Psychology and Physiology Study of Noise Signal:
The different noise signals were simulated in term of sound characteristics. The subjective psychology assessment was carried out to analyze the effect of noise signal parameter. The object physiology index, especially brain activation index, were collected to study the relationship of psychology feeling and physiology reaction.

Sound quality control of city environment:
A new type composite structure was developed by containing good sound absorption property and good sound diffusion property. The transmission loss of barrier with composite structure top can improve 10dB in the low frequency. According to the state standard, sound quality can be controlled by analyzing the city environment noise property. The relevant treatment and management policy were developed.

Research Interests

Main objective is to reduce or eliminate persistent organics from water or soil. The method is to produce highly active radicals, such as hydroxyl radicals, by catalytic activation of O2 or H2O2 through approaches like photocatalysis or Fenton-like catalysis. I am trying to explore the mechanism on how to fabricate advanced functional materials with high catalytic activity, to understand the primary processes in the catalytic reactions, and to promote the applications of these materials and related technologies for water purification or soil remediation. My recent projects include two parts: to remove antibiotics and other organic micropollutants from water; and to remediate polycyclic aromatic hydrocarbons polluted soil.

In geotechnical engineering his interest is principally in the design of offshore foundations, although in the past he has also worked on in-situ testing, reinforced soil and tunnelling. He also works on the applications of numerical methods (both finite element analysis and other methods) to solution of geotechnical problems, and on the development of constitutive models for soils.

Much of his recent research has been applied to the area of marine renewable energy. He has carried out research on foundations for offshore wind turbines, and is currently working on the development of a novel tidal turbine for power generation. He also has a substantial group working on the understanding of tidal resources at every scale from single devices through to tidal basins.

My second research line is aimed to unravel chemical and microbial processes that control the cycling of trace metals and to see how these processes are affected in the context of global climate change. Overall, I strive to use my knowledge and skills to solve the myth of environmental toxicology and biogeochemistry of trace elements, and to address real world environmental problems that confront us.

Research Interests

Researches mainly in reclaiming heavy metals from polluted soils/sludge, wastewater treatment models and software, utilization methods of energy resources. A lot of toxic organics are produced and released into the environment each year. Their hazards and treatment techniques are always a heated topic. Advance chemical oxdation is an effective method and its test experiments are sufficient. The degradation of organics in oxidation process must take place under three main steps, (1) oxiants (OH radical, O3 at all) closely approaching to organic molecule; (2) oxidants adding to active organic rings. (3) Breaking down of the main or several interring chains and producing small compounds. Based on this oxidation mechanism and QSAR models, a “three-factor” mechanism of oxidation process is proposed. It is beneficial to predict the treatment effect or environmental degradation behavior of toxic organics.

Research Interests

Focus on emerging contaminants, including environmental behaviors and fates, trace analysis, wastewater treatability, health effects and human exposure assessments of the antibiotics, bisphenol A, personal care products and algae toxins etc. He initiated several studies on the adverse effects of mode organism and human cell exposed to low dose/environmental relevant concentration of emerging contaminants. The specified proteins, genes and molecular docking studies are carried on to understand the mode of action, gene-environmental interaction and epigenetics modification. In addition, indoor dust and human urine samples are being collected and analyzed to investigate the exposure risk and human disease associations.

Research Interests

Focus on the detection of nanoparticles and emerging contaminants in the water environment, and their environmental implications, including their behavior, fate, and biotoxicity. The asymmetrical flow field flow fractionation coupled with multi-angle light scattering (AF4-MALS), combining with ICP-MS or LC-MS-MS to separate the nanoparticles and identify and quantify pollutants carried by nanoparticles in the water. Our results show nanoparticles (<20nm) in the water carried a large amount of organic constitutes, and might get away from the water treatment process and exert the risk for the environment and human health. Manufactured carbon-based and metal, metal-oxide based nanomaterials are selected as model nanomaterials to study their biotoxicity on plankton and invertebrate animals by transcriptomic and metabolomic ananlysis. Our results show these nanomaterials form aggregates while entering the water, and their toxicities are complicated, depending their size, surface coating, and environmental factors. The transcriptomic and metabolomic analysis are effective methods to detect their biological effect at environmental relevant concentrations.
