Asst Prof Brendan Patrick Orner
The overall research undertaken in our lab has two fundamental goals, both focused on the chemistry/biology interface. One goal is to develop new methods and technologes, while the second goal is to investigate fundamental questions. The philosophy of the lab is to mesh each of the goals so that they can feed into the other in a smooth and dynamic manner. The new technologies will be utilized to help answer fundamental questions and this basic research will necessitate the development of additional methods. The novel techniques will be developed with an eye on generality and additional applications. They will initially focus on combinatorial techniques that not merely employ vast collections of molecules, but unleash the power and intellectual statisfaction of focused design. The fundamental biological systems of interest will be focused on understanding the role protein-protein interactions play in the key cellular process of apoptosis (controlled cell death), how primary, secondary, and tertiary structure of proteins afeect their quaternary structure and self assembly proceses, and wheter it is possible to convert overly reactive, non-specific compounds into specific ones that target key HIV and Alzheimer's Disease proteins.

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.

Prof Ng Wun Jern
NG WUN JERN's research interests are largely in the area of water and wastewater management. The focus of his efforts has been on investigations into water quality, treatment science, and development of treatment technologies. These investigations span the water quality spectrum - ranging from ultra-pure water to high strength and potentially inhibitory wastewaters. His research output may be found in some 400 publications. These include journal papers, conference presentations, book chapters and monographs, reports, and patents. His latest book publication is titled "Industrial Wastewater Treatment" (Imperial College Press). He is currently working with colleagues on a book on engineered wetlands in tropical applications and one on water reclamation. Current R&D interests revolve around effluent treatment and include dehalogenation under bioreductive conditions. Of particular interest are the chloro-compounds and dehalogenation under acidic conditions with biomass sculptured into granules. The interest in bioreductive (instead of bio-oxidative) processes stems from concern over energy costs and carbon footprints of treatment processes. Anaerobic processes are therefore of interest when used to manage strong wastewaters from industrial and agro-industrial sources. Current R&D interest focuses on thermophilic anaerobic processes and gas productivities and quality. Conceptually there is a shift from viewing the anaerobic process as a wastewater pretreatment device to one which is intended to recover energy from the wastewater. Extending this interest is the work on biosorption where sorption is used to concentrate carbonaceous material from low strength wastewaters prior to anaerobic degradation of the sorbent with gas recovery. This approach deviates from the conventional approach of using anaerobic processes such as the UASB or anaerobic filter to address low strength wastewaters. Laboratory studies typically use the cyclic process configuration although larger scale studies can be with the cyclic or continuous flow configuration. 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).

Prof Peter Rainer 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. 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. yoelii we have been able to address question relating to mechanisms regulating parasite virulence as well as getting a cleared understanding on how these large proteins mediate their function. An interesting upshot of this work is the possibility of using them as part of a malaria vaccine formulation. In addition to merozoite invasion the lab has also spend significant effort in elucidating the biological role of the STEVOR and PIR multigene families identified in P. falciparum and P. vivax respectively. While STEVOR is unique to P. falciparum the PIR multigene family is found not only in P. vivax, but also rodent and simian malaria parasites. 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. We are now further characterizing how STEOVR functions. 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. vivax. 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. falciparum and P. vivax microarray platform developed here at NTU (in collaboration with Professor Zbynek Bozdech) to investigate differences in the transcriptional profile of parasites obtained directly from patients with different clinical symptoms. This effort has recently given significant new insights into the biology of P. vivax.

Asst Prof Sum Tze Chien
A. Energy Transfer Mechanisms in Doped Semiconducting Nanostructures In this work, we seek to understand the dynamics of the energy transfer processes between the host and the dopants in a doped semi-conducting nanostructure system (i.e. Mn-doped ZnS spherical nanoparticles and nanorods). We are particularly interested in understanding the spin-flip processes between the host and the dopants. The system will be probed using both time-resolved photoluminescence and transient absorption spectroscopy. The knowledge gained would aid in the fabrication of nanoparticles/nanorods with enhanced luminescent efficiency through suitable surface modifications and processing. B. Energy Transfer Mechanisms in Organic Light Emitting Devices & Organic Photovoltaic Devices In this work, we seek to understand energy transfer mechanisms in organic electronic devices under electrical and optical excitation, in particular that of the exciton and polaron dynamics resulting from interchain effects in an OLED under device conditions (field-induced changes in the optical behaviour). The radiative recombination pathways will be investigated using both time-resolved photoluminescence and time-resolved electroluminescence. The non-radiative relaxation pathways will be probed by transient absorption spectroscopy. The knowledge gained would serve to guide the design of such organic materials in improving luminescent efficiency through chemical and structural modifications. C. Relaxation Dynamics of Colossal Magneto-Resistance Manganites Colossal magnetoresistance (CMR) manganites have been subjected to extensive research due to their unique magnetic and electrical properties. The physical origin of this phenomenon has been attributed to the double-exchange model. However, this double-exchange mechanism of carriers between Mn3+ and Mn4+ ions alone cannot account for all the observed changes such as metal-insulator transition in these materials. Other factors include the highly correlated nature of the spin, lattice, charge and orbital degrees of freedom. Ultrafast optical techniques are powerful probes for investigating the quasi-particle and spin relaxation dynamics in these strongly correlated systems. D. Relaxation Dynamics of Highly Spin-Polarized Ferromagnetic Systems In this work, we seek to understand the spin-relaxation mechanisms of a highly spin-polarized ferromagnetic system (e.g. (La, Sr)Ti1-xCoxO3) on the ultrafast and Landau-Lifshitz-Gilbert time scales. These relaxation mechanisms involve electrons, spins and lattice as well as the different couplings in between them. The detailed understanding of the spin-relaxation mechanisms is still lacking. TR-MOKE measurements address the demagnetization and relaxation of the spin system while transient reflectivity measurements give an insight on the electronic and lattice relaxation processes. The knowledge gained would guide the design of oxide DMS spintronic devices such as spin injection devices and spin FETs.

Asst Prof Zhao Yang
Miniaturization of electronic and mechanical devices over the past century has brought immeasurable impact onto human lives. Commercial microelectromechanical systems have reached micron scales, and bona fide molecular apparatuses began to emerge setting the stage for upcoming integrated nanoelectromechanics. Dr. Zhao and coworkers systematically investigate carbon-nanotube-based oscillators, bearings and rotators via molecular dynamics simulation in order to establish their optimal operating conditions and to facilitate function-oriented designs. In addition, particular attention is paid to utilization of nanomachinery devices as nanolabs to study energy exchanges among various degrees of freedom, ergodicity on energy surfaces, and equipartition as systems relax, and to test fundamental hypotheses of thermodynamics and statistical mechanics. The advent of ultrafast femtosecond laser spectroscopy brings about intense research interest in relaxation dynamics of photo-excited states in liquids and solids. Newly-arrived technological capabilities to control femtosecond pulse durations and down-to-one-hertz bandwidth resolutions provide novel probes on vibrational dynamics and excitation relaxation. Dr. Zhao and coworkers formulate time-dependent polaronic wave functions that facilitate microscopic modelling of photo-generated excitation relaxation and realistic computation of various third-order optical response functions, and help to achieve a satisfactory comparison between theory and experiment. Carbon nanotubes are attractive candidates for a variety of applications thanks to their remarkable physical, chemical, and mechanical properties. Optical absorption and fluorescence spectroscopy measurements have become an important tool for structure-based characterization and DNA-assisted manipulation of carbon nanotubes. Dr. Zhao and coworkers establish visual, intuitive connections between optical absorption line shapes and their underlying nanotube structures, which are scrutinized by more sophisticated semi-empirical and DFT calculations.
