Academic

Dr Sisi Liu is an Online Course Facilitator(OCF) for the Bachelor of IT & Data Analytics degree at Adelaide University Online. She received her PhD from James Cook University in 2020 and was awarded the International Research Training Program Scholarship(IRTPS) funded by the Australian Government – Department of Education and Training to support her doctoral research project. 
She has a comprehensive experience in online teaching and digital learning. Courses that she had facilitated cover the areas of Information Processing and Visualisation, Programming, Database Modelling and Systems, Advanced data analytics and Machine Learning. Currently, she is the principal investigator of a funded project(~$25k) on a GenAI-Enhanced Web Application to Capture and Personalise Student Cognitive Engagement in Asynchronous Text-Based Communication.
She is also an active researcher in the field of learning analytics, educational data mining and GenAI and have published several articles in the leading journals and international conferences, such as Knowledge-based Systems, Expert Systems with Applications and Australasian Society for Computers in Learning in Tertiary Education.
Her current research interests include Text Analytics and LLM, GenAI-enhanced Learning Analytics, Computational Linguistics.
