Fang Chen

Research Leader


Previous Positions

Dr. Fang Chen was employed with Beijing Jiaotong University in China from 1995-1999. She was appointed Associate Professor of the Faculty of Electronic and Information Engineering in 1995, the Deputy Director of the Institute of Information Science in 1996 and then Dean of Faculty of Electronic and Information Engineering in 1997.

Dr. Chen began her career in industry in 1999 as senior researcher and Team Leader in Intel China Research Centre. She joined Motorola in 2000 as  Principal Researcher and founding manager of the Speech and Language Generation Research Lab of Motorola China Research Centre, where she also acted as the account manager of business relationships for the Motorola China Research Centre.

Dr. Chen moved to Australia in 2002 to work for the Motorola Australian Research Centre, where she chaired the Patent and Publication Committees.

She joined NICTA in 2004 and is currently the Research Leader at the ATP Laboratory in Machine Learning Research Group.

Qualifications

Dr. Chen holds PhD in Communications and Electronic Systems and an MBA.

Research Interests

Dr. Chen's main research interests are behaviour analytics, especially in human machine interaction, cognitive load modelling, speech processing, patterm recognition, human and system performance prediction and evaluation. She has more than 100 refereed publications and filed 27 patents in Australia, US, Europe, Canada, China, Japan, Korea and Mexico.

NICTA Past Projects

Dr. Chen was the Research Group Manager for the Making Sense of Data (MSD) research theme at the ATP Laboratory. Projects under this theme:

  • The Decision Support for Incident Management (DSIM) project aims to research and develop core technologies for a new generation of human computer interfaces that support critical decision-making for users in high-performance and time critical environments. The research focuses on i) measuring the cognitive load experienced by human operators of large volume and complex information systems, in real-time and in an unobtrusive way; ii) optimising joint human-system integration via adaptive decision support based on human cognitive status and situational context.
  • Human Performance Improvement (HPI). When elite athletes become fatigued their competitive edge may be lost. In Emergency Services and Defence, fatigue may be fatal. Monitoring human performance is critical to ensure safety and peak competitive output. Coaches and commanders need to monitor personnel in training and in the field, and to have instant feedback on performance. At present, athletes and soldiers are monitored under special laboratory conditions, have data returned to base after several days of logging, and may fill out surveys to determine their own performance. Coaches and commanders want real-time feedback of performance: the challenge is to interpret, transmit and display the information. There are two work packages from HPI is under MSD theme at ATP lab.
  • The STaR-UI project proposes to introduce multimodal input technologies and the fusion of these inputs and cognitive load based multimodal output generation to address the need of control rooms. The project is developing technologies that efficiently guide control room operators through processes such as incident response, to automatically generate reports and present other relevant information to the operators as they proceed. The project is also developing and implementing cognitive load management techniques to streamline interaction with various traffic management centre applications enabling more effective application integration and more reliable traffic management operations.
  • The Braccetto project is a collaborative project in human-machine interaction. It aims to develop sophisticated information sharing technology that can help geographically distributed teams collaborate more effectively. The project is developing new methods for supporting simultaneous work on software applications between sites in conjunction with tightly linked, high-quality, multi-party telepresence technology. The project will evaluate how these methods improve the productivity of teams and team members’ awareness of co-workers.
  • The DMiST project combines the areas of computational geometry, data mining, data bases and algorithm design. The movement of objects (e.g. cars, people, animals) can be represented by trajectories in the plane. Analysing these provides and trying to find interesting patterns such as where animals meet to form a flock is the aim of the project.

Affiliations

Dr. Chen has received Conjoint Professor and Honorary Associate positions with the University of New South Wales and the University of Sydney. She is also an adjunct professor in Beijing Jiaotong University.
