My research is in the area of information access and retrieval, focusing on understanding how systems such as search engines can assist users to resolve their information needs, and how their effectiveness can be measured.
I'm Deputy Director of the RMIT Centre for Information Discovery and Data Analytics (CIDDA), which brings together experts across different academic disciplines, schools and colleges including computing technologies, science, maths and statistics, engineering, and business.
Some of my other key research activities involve the ARC Center of Excellence in Automated Decision-Making and Society -- focusing on issues around fairness, accountability, transparency and ethics of systems and algorithms -- and the RMIT FactLab research hub -- focusing on misinformation, fake news and fact-checking.
I teach a range of courses, including on web development and programming, data science, HCI, databases, and information retrieval. I'm also the Program Manager for the postgraduate Master of Data Science.
In the area of human research ethics, I am Chair of the STEM College Human Ethics Advisory Network (CHEAN), and a member of the RMIT Human Research Ethics Committee.
