In aerobic treatment, there is interest in the MBR applied with granulated biomass. The interest is on biofouling mitigation using this modified biomass morphology. There is also interest in using the MBR and the concept of "back seeding" to achieve better nutrients removal and degradation of resistant organics eg textile dyes. Aerobic processes are also used to produce enzymes, phytohormones, and beneficial microbial consortia from horti-and agri-wastes.


NG now leads his own research group, the Environmental Bio-innovations Group EBiG , which as its name would suggest has focus on solutions which can be applied on the issues faced in the region. While not limited to bioprocesses, there are more numerous such solutions with intention to achieving more sustainable and circular approaches. His current research works focus on Nanostructured Magnetic Materials Prof Peter Preiser My research interests focus on the molecular mechanisms by which the malaria parasite is able to avoid host immunity and adapt to changes in the host cell environment.

One of the main problems in developing an efficient malaria vaccine is the ability of the parasite to evade host immune responses. Immune evasion happens both at the level of the infected red blood cell and at the process of invasion, the step at which the parasite infects a new cell. A key focus area of the lab is to understand the mechanisms on how the malaria merozoite recognizes and penetrates the erythrocyte.

An introduction to nanoparticles and nanotechnology

To address these questions we have particular focused on the role of the Reticulocyte Binding Protein Homologues RH family of proteins which is found in all malaria species and has been implicated on playing a role in immune evasion and parasite virulence. Using both the human parasite Plasmodium falciparum as well as the rodent parasite P. An interesting upshot of this work is the possibility of using them as part of a malaria vaccine formulation. My research group has focused on developing a range of reagents that allow us to address what the role of STEVOR is in parasite development.

We have recently been able to show that STEVOR is highly expressed in patient isolates and may play an additional role in immune evasion. The PIR gene family provides a unique opportunity to study antigenic variation in a rodent model and possibly utilize the information gained in this system to understand how these genes may work in the intractable human parasite P. Currently, our efforts focus on understanding how the pir genes are transcriptionally regulated. A more recent effort is to gain new insights into how human malaria parasites interact with their host. Until recently most research efforts have focused on using culture adapted parasites but it has become clear that significant information in relation to host parasite interactions are lost in this system.

We are therefore interested in using the P. This effort has recently given significant new insights into the biology of P. His group uses a combination of physical, chemical, biological and computational methods to investigate and manipulate properties of biomolecules.

Associated Data

He has been working on design, simulations and fabrication of novel electromagnetic devices including metamaterials, plasmonic resonators and complex oxide transition materials, while simultaneously exploring their applications in information, sensing and energy. Metamaterials have been found to possess exotic properties and effects that are beyond the realms of materials that exist in nature.

His contributions in the field so far has been in the terahertz region where he demonstrated classical active and passive analogues of electromagnetically induced transparency through near field coupled metamaterial resonators, sensing with metamaterials, chiral metamaterials, ultra-high quality factor Fano resonances, and ultrafast superconductor metamaterials. Some develop stress-related psychopathology, anxiety, depression, dementia, while others weather it well and even emerge healthier.

What makes some individuals resilient and others not? Stress is known to cause brain damage, shrink neurons of hippocampus memory center of brain and enhance emotional learning along with neuronal growth in amygdala emotion center of brain. Our research Resilieo is geared to find out how we can minimize and prevent brain damage caused by stress.

With this backdrop, we venture into 4 different lines of investigation. Is there any difference in brains of resilient and vulnerable individuals? Our study on rats exposed to predator stress showed distinctive pattern of neuronal branching within amygdala of resilient individuals.

Well-adapted resilient animals had more densely packed neuronal branching and maladapted vulnerable animals had more spread out neuronal branching of amygdala neurons. Questions we are pursuing now include, what determines individual variation in neuronal branching? And what are the possible factors mediating this? How to rescue or prevent stress-induced damages enhance resilience?

In addressing this question we employed gene therapy as a technique to deliver genetically altered proteins through viral vectors into specific brain regions. Targeted infusion of therapeutic molecules within amygdala rescued stressed animals from maladaptive anxiety, abnormal stress-response and neuronal over growth hypertrophy. We continue to identify newer molecules for therapeutic intervention within amygdala and other brain regions.

Developing animal model of resilience Enriched environment is known to induce positive behavior and protection against brain damage. We are testing different enrichment paradigms to develop a testable animal model of resilience. Initial results are promising. Short term enrichment rescues maladaptive fear response in stressed animals.

Are resilient individuals better adapted? In an interesting new finding we showed that male rats exposed to enriched environment for a short 2 week period were more attractive and preferred as mates by females over non-enriched males. The enriched male rats also had stronger defense response against predator. Thus resilience not only makes individuals cope better with stress, but also has a bigger scope of adaptability in an ever-changing environment.

We continue to investigate how enrichment drives basic physiology to be more adaptive? What are the pathways and molecular factors triggered by enrichment in this context? He has also worked extensively on the design, fabrication and characterization of high frequency, high power and high temperature SiC power devices. His current research works focus on silicon nanowires and their applications.
