Stephen Wan

  • Associate Investigator


Dr Stephen Wan is a computer scientist specialising in computational linguistics, an inter-disciplinary field that draws on both linguistics and computer science. His research employs natural language processing and text mining methods, in conjunction with machine learning, information retrieval and human computer interaction techniques.

With over 20 years of research experience, Dr Wan leads a team of software engineers and researchers to build information management systems for a variety of text data types. A common element in these systems is the need to extract actionable nuggets of information that will help with a user’s task. His team has developed systems used by both the government and private sector for areas such as business intelligence, social media monitoring, and information systems for scientific literature.

Currently, Dr Wan’s team is investigating research directions in natural language processing and information retrieval that supports research in other scholarly fields. The work, part of Data61’s “AI for Science” direction, currently spans multiple disciplines, including computational social science, mental health, precision health, ecology and conservation, and agronomics.
