Vg Asst Prof Andrea Nanetti	All results of my research career convey into Engineering Historical Memory (EHM) (http://www.engineeringhistoricalmemory.com). EHM is both an experimental methodology and an ongoing research project for the organization of historical information in the age of data revolution, that I theorized when I was Visiting Scholar at Princeton University in 2007, to develop and test new sets of shared conceptualizations and formal specifications for content management systems in the field of heritage science. What sets it apart from other approaches is a focus on developing and applying computationally intensive techniques to achieve this goal (e.g. pattern recognition, data mining, machine learning algorithms derived from other disciplines, and visualization solutions). The preliminary sets of formal specifications and results of tests on highly cross-linked historical data have been published in Italy in 2008 (local urban historical memory transmission), 2010 (world views and networks), and 2011 (regional man-heritage-landscape systems) when I was Adjunct Lecturer in the Faculty of Cultural Heritage Conservation of the Alma Mater Studiorum-University of Bologna (Italy). For details, see the publications list on my personal homepage http://www.andreananetti.com The master plan designing and the Web strategies of EHM are developed by Meduproject Ltd. (a company that I established in 2002 as academic spin-off of the Department of History and Methods for Cultural Heritage Conservation of the University of Bologna, after having been awarded in 2001 a prize in the first Italian business plan competition devoted to projects with high content of knowledge and having been financially supported by the Italian National Agency for New Technologies, Energy and Environment). Research teams and fundraising are working in Venice, People's Republic of China, Australia, USA, Turkey, Russia, Egypt, India, and Singapore. Using English as lingua franca, heritage science scholars of all countries are invited to use EHM to organize and share literary, documentary, art historical, cartographical, archaeological, photographical, oral, and musical data sets. EHM, as a research project, is based on the question “What shall the historian do having all data available in a digitalized form?” What the implications will be for studying the past when ALL archival materials will be digitized and available in any language? From a media perspective, the challenge is to let the system work on a visual base for art historians interested in investigating technological intercontinental networks: data mapping and visualization of the diffusion of technologies related to art (ceramics/porcelain, silk, glass, paper, lost-wax casting bronze production, pottery kilns, and so on). If the general spirit is shared with Wikipedia, Wikimapia (where users and guests mapped over 20'000'000 objects on an interactive global map), and other collaborative databases, what makes the difference here is the application of the highest standards of scholarly edition and publication for each different typology of historical source. The most recent engagement of the project is to develop and test tools (technologies and processes) that can be readily adopted by all users to visualize high volumes of data through maps, timelines, tag clouds, and/or interconnected graphs on different scales. Because, not only historians and art historians, but also artists, students, and all sorts of other users will be welcome to create and share their own narratives, by tagging, connecting and recognizing links among elements of the historical landscape.

Assoc Prof Arul Indrasen Chib	Dr. Arul Chib focuses on mobile phone healthcare systems, and pursues action-oriented research in varied cross-cultural contexts, particularly in resource-constrained environments. He investigates the key factors influencing the adoption of technology for positive health outcomes, and has engaged in the design and development of healthcare technology systems spanning online and mobile platforms. Global collaborations with IDRC, UNICEF, and UNFPA have led to research grants of S$3.7Mn. His work with Acehnese midwives has led to great interest in the field of mobile health (mHealth) technologies. Of note is that the original JAVA application for mobile phones was developed in 2006, well in advance of the latest innovations in mobile-based applications. This ground-breaking technology to improve maternal and infant health was developed for 223 rural midwives based in the tsunami-affected region of Aceh Besar, Indonesia, impacting as many as 600 villages. This ICT project, facilitated by cell phones and data sending mobile technology, uses the existing pool of knowledge in the rural health system to bolster local resources. Prior to working on tsunami relief, Dr. Chib collaborated with a Peruvian NGO, Instituto Peruano de Paternidad Responsable, to develop an interactive computer-based multimedia game to deliver information about sexual and reproductive health, particularly about HIV/AIDS. Dr. Chib is currently extending his work in mHealth by examining issues of power and influence caused by the mobile phone usage amongst community healthcare workers in Papaua New Guinea, Thailand, India, and China. Dr. Chib's contributions have led to a number of research awards, including the 2011 Prosper.NET-Scopus Award for the use of ICTs for sustainable development. This award was accompanied by a fellowship from the Alexander von Humboldt Foundation, one of the highest honours within the European scholarly tradition. He has been awarded fellowships at Ludwig Maxmilians University and University of Southern California, and the Best Graduate Student Award of S. I. Newhouse School of Communications at Syracuse University. He serves on the editorial boards of Human Communication Research and Communication Yearbook, the flagship publications of the International Communication Association. Chib has published in the best refereed journals, such as the Journal of Computer-Mediated Communication, ranked first amongst Thompson Reuters communication journals, the Journal of Health Communication, ranked first amongst health communication journals, and Information Technologies & International Development, ranked first amongst journals in the field of information and communication technologies for development. He has contributed to book chapters from leading publishers such as Cambridge Scholars, Hampton Press, Springer, and Taylor & Francis. In 2012, along with Dr. Roger Harris, he released the edited volume, Linking Research to Practice (2012, ISEAS Singapore). His research papers have been adopted as syllabi in institutions in Copenhagen, Geneva, Manila, and Virginia. He is currently working on the authored book, mHealth in Developing Countries (forthcoming, Taylor & Francis UK). Dr. Chib’s work in as many as nine countries has been profiled in media outlets ranging from the United Nations Chronicle to the Singaporean press. He has been a guest speaker at numerous global events, and in 2012, gave the keynote speech at the Media Health Communication Conference in Munich. He is a member of the organizing committees of the IFIP 8.6 2013 and ICTD 2012 conferences. As Assistant Director at the Singapore Internet Research Center, Dr. Chib leads the Strengthening Information Society Research Capacity Alliance programme. This multi-year capacity building programme has mentored 30 emerging researchers in Asia, Africa and Latin America, and organized training events in Atlanta, Bangkok, Jamaica, and Singapore.

Assoc Prof Boh Wai Fong	My scholarship examines how information technology and other mechanisms can be used to facilitate knowledge and information sharing across individuals, groups and organizations. My research tends to focus on the problems of knowledge and information sharing, and I investigate how technology and other mechanisms can be used to effectively solve these problems. Recently, I have also began to expand my research into related areas of expertise management for innovation. I have completed several research projects ? many of which are large scale empirical studies examining knowledge and information sharing at different levels. Allocation of Human Capital Resources. My research has shown that the allocation of human capital resources to different types of work and project teams have significant implications on learning and knowledge sharing, leading to better performance. For example, my work on software developers show that organizations should consider trade-offs between allocating software developers to work on specific systems to gain specialized experience versus allocating software developers to work on related and unrelated systems to gain diverse experience (Boh, Slaughter and Espinosa, 2007). Another research project also shows that appropriately allocating experts to project teams where their expertise is required overcomes the costs of coordinating across distance (Boh et al, 2007). I am also currently engaged in a research project examining how individuals? breadth and depth of expertise influences innovation success, and how organizations should allocate individuals with different expertise profiles to work on product development projects. Knowledge Management. More recently, my work has focused on examining how various mechanisms such as the use of information technology can help organizations to more effectively share the knowledge embedded in individuals. My studies show that contrary to conventional thinking, which tends to view knowledge sharing mechanisms as either technology or people-oriented, different knowledge sharing mechanisms are complementary in nature (Boh, 2007). Hence, designing a portfolio of mechanisms (beyond simply the use of information technology) based on the characteristics and culture of the organization is critical for effective knowledge sharing. Enabling Information Sharing across Organizational Units and Organizations. I believe that information technology plays a very significant role in facilitating information sharing across business units and organizations. Hence, some of my recent work examines how organizations can make use of IT standards and enterprise architecture to facilitate the integration and sharing of data across business units in a large organization (Boh and Yellin, 2007), or across organizations in a supply chain (Boh, Soh and Yeo, forthcoming).

Asst Prof Martin Constable	I am deeply fascinated by the way that compositing technologies (like Photoshop and Nuke) have changed the shape of our culture. The role of the artist has been completely re-defined by these technologies, a change that is comparable to the change wrought upon painters by the invention of photography. In my work as an artist I try to cross-breed the disciplines of photography, painting and visual effects. My other line of research is in the field of computational aesthetics. I have been working in collaboration with computer engineers on problems relating to the automatic and semi-automatic augmentation of the aesthetic attributes of photographs. One key aspect of this work is the realization of how important contrast is in determining the key style aspects of an image. Though this work is ongoing, I can say that image contrast is not what most people think it is. One of my first projects in NTU was to design a Blackboard tool ('Visual Acuity') to aid the grading of visual art assignments. This was such a success that it was instituted by the university as a permanent fixture. Currently I am completely hot for the possibilities offered by the Lightfield camera (Mark Levoy et al: http://graphics.stanford.edu/papers/lfcamera/). I doubt that many people fully realize how much this technology can cnage the way that we think about images and the way that we edit them. Some wikis: (eratic server, please be patient) - My teaching Wiki on Photoshop use: http://opticalenquiry.com/photoshop - My teaching Wiki on Nuke (compositor) use: http://opticalenquiry.com/photoshop - My Wiki covering ther work produced by my artists collaborative 'Grieve Perspective': http://http://grievethink.com One of the most exciting things about working at NTU is the wonderful possibilities available for collaboration with engineers. Any form of inter disciplinary collaboration is difficult, and science and art collaboration even more so. However the rewards are substantial. One of my heros in this regard is Albert Munsell (http://en.wikipedia.org/wiki/Albert_Henry_Munsell) an artist whose asked a few simple and fundamental questions about color. In exploring these questions he developed the Munsell Color System which in turn became the Lab color space.

Assoc Prof Sia Siew Kien	Enterprise Resource Planning ERP systems represent a major change in organisational information systems in terms of their scale and scope, reliance on vendors and advocacy of best practices. They are pervasive and often mission critical. Streamlining and integrating organisational procedures and standardising them over a single platform were what these systems promised. However, cases of expensive ERP implementations going awry has led many to recognise the inherent challenges of successfully implementing such complex package software. Research is currently in progress on these themes: (1) cultural fit of the underlying ERP business models, (2) partitioning the sources of misfits in ERP, (3) challenges in analysing, designing, and implementing ERP, and (4) ERP as an leverage for enterprise integration. Achieving Global Excellence in Asian Companies: Strategy, Governance and Technology The growth of the Asian market has led to the development of a select group of Asian companies that have successfully established an international presence. How did these enterprises transform themselves to capture the opportunities in the international market? What strategy and governance principles have they used? How has information technology enabled scale, responsiveness, and innovation in the highly volatile business environment? This research study seeks to understand the practices followed by a handful of leading Asian companies that have clearly established themselves as global leaders.
Assoc Prof Siew Chee Kheong, David	Research A/Prof Siew's research interests span three areas: (1) Quality of Service (QoS) Provisioning; (2) Congestion Control; and (3) Application of intelligent control to networking problems. The underlying network could be a wired, wireless or optical network. (1) While there is no shortage of proposed packet scheduling algorithms, our approach to the problem is slightly different. We are particularly interested in practical issues in search of low computational-complexity fine-granularity scheduling together with admission control that provide per-flow deterministic guarantees using class-based traffic treatment. This work would allow efficient QoS provisioning with specific queueing delay bounds. Our approach is to provide low-complexity service-curve based scheduling and admission control. Using nice properties of service-curves, we are able to avoid packet-by-packet analysis but provide an elegant analysis of the complex end-to-end QoS provisioning. We have recently proposed a low-complexity Flow-state-dependent Dynamic Priority Scheduling (FDPS) algorithm that could provide a service-curve based packet scheduling engine that enables per-flow deterministic guarantees. My recent in-press publication on per-flow QoS using class-based treatment is listed in [2]. (2) My interest in Congestion Control is to improve the Transmission Control Protocol (TCP) fairness and prevent TCP collapse in best-effort networks. It is well-know that TCP performance is highly dependent on Round-trip-time (RTT), an issue that has attracted many investigations. While most existing works attempt to provide solutions at the transport-layer, our approach uses both the features of network-layer and transport-layer. Our recent work [1] demonstrated that our solution could improve TCP fairness by reducing dependence on RTT, and prevent TCP collapse by means of intelligent packet discarding [1]. It has been proven that classical TCP will not be efficient in such high bandwidth-delay product networks. As a result, we are currently interested in providing a comprehensive solution to networks (e.g. Grid computing networks) with high bandwidth-delay product. The issues of max-min fairness and rate of convergence are converging issues for the research. (3) We are interested to apply intelligent control to network problems would include stochastic QoS guarantees and/or wireless network carrying heterogeneous traffic. These works could involve cross-disciplinary solution using control theory, fuzzy logic or artificial intelligence. The natural progression of such works would be Application-layer QoS provisioning in which cross-layer issues dominate. We are currently interested in applying distributed algorithm for collaborative wireless networks. Solutions are needed for many challenging issues on how rate, delay and access control in this area.
