ABOUT ME

Daphne Lai is a Computer Science Lecturer at the Faculty of Science, Universiti Brunei Darussalam where she has been a faculty member since 2004.

Daphne completed her Ph.D. at Nottingham University, MSc at University of Kent, Canterbury and and her undergraduate studies at Strathclyde University.

Her research interests lie in the areas of data mining and artificial intelligence, ranging from applied as well as design. In recent years, she has been investigating on better techniques for cluster analysis. She is collaborating with researchers in several disciplines of health care, particularly cancer registry and cardiac rehabilitation.

She currently serves on the Steering Committee for ASEAN-IVO under NICT and is also a IEEE member.

Daphne is currently lecturing in Programming Fundamentals and Computer Programming.

SOCIAL, ECONOMIC, or ACADEMIC BENEFITS

Patterns that are not easily determined can be found using data mining techniques, allowing the prediction of outcomes on new data records. Applied in the biomedical field, this enhances the understanding of the disease and its outcome through characterisation of these patterns based on the parameters.
