Modeling the propagation and defense study of internet malicious information

 Dr. Wen's research includes modelling the propagation dynamics of malicious information, exposing the most influential people and source identification of epidemics in social networks. His research is beneficial to both academia and industry in the field of Internet social networks.

Security and privacy of users' personal Information on smartphones

 This research investigated the proliferation of malicious applications on smartphones and a framework that can efficiently detect and classify such applications based on behavioural patterns was proposed. Additionally the causes and impact of unauthorised disclosure of personal information by clean applications were examined and countermeasures to protect smartphone users’ privacy were proposed.

Information discovery in multi-dimensional autonomous wireless sensor networks

 The thesis proposed four novel algorithms of information discovery for Multidimensional Autonomous Wireless Sensor Networks (WSNs) that can significantly increase network lifetime and minimize query processing latency, resulting in quality of service improvements that are of immense benefit to Multidimensional Autonomous WSNs are deployed in complex environments (e.g., mission-critical applications).

Exploiting side information in Bayesian nonparametric models and their applications

 My research is to exploit side information into advanced Bayesian nonparametric models. We have developed some novel models for data clustering and medical data analysis and also have made our methods scalable for large-scale data. I have published my research in several journal and conference papers.

Acceptability of videoconference technology for the delivery of continuing education to rural pharmacists

Aim: To investigate whether a rural continuing education (CE) program delivered by videoconference can enhance access to, and uptake of, CE among pharmacists and determine their satisfaction with videoconference for the delivery of CE. Method: A postal survey was sent to 33 registered pharmacists in south-west Victoria and south-east South Australia who had attended at least one videoconference CE session organised in that region. Results: Respondents worked in different areas of pharmacy, and 40% worked in more than one area of pharmacy. The use of videoconference facilities has increased access to and participation in CE generally, and most participants (88%) have found it to be an acceptable medium for delivery. Increased access to high-quality CE opportunities, and reduced travel time for CE were seen as the principal benefits of the medium. Negative aspects included technical glitches, organisational issues, and the time-lag in voice transmission. Overall, most participants were happy to receive a substantial proportion of their contact CE using this medium. Conclusions: Videoconference technology is a valuable tool for the delivery of carefully structured CE sessions in rural and remote areas with an appropriate information technology infrastructure.

Assimilating healthcare information systems in a Malaysian hospital

The importance of information systems/information technology (IS/IT) to healthcare organisations is being recognised today as paramount and critical in order to realise superior healthcare delivery. Successful assimilation of IS/IT, which is the central focus of this study, then becomes a key consideration in ensuring that IS/IT is appropriately and systematically deployed into a healthcare organisation. The key findings from this research indicate that there are people, process, technology and environment elements that should be considered as facilitators to the healthcare information systems (HIS) assimilation process, as well as barriers that the healthcare organisation should overcome throughout the entire assimilation process or at specific stages. This research, therefore, is not only topical but especially beneficial to management and administrators in the web of healthcare players as they grapple with trying to successfully assimilate HIS into their respective organisations. © 2014 by the Association for Information Systems.

Securely sharing dynamic medical information in e-health

This thesis has introduced an infrastructure to share dynamic medical data between mixed health care providers in a secure way, which could benefit the health care system as a whole. The study results of the universally data sharing into a varied patient information system prototypes.
