I am a PhD Candidate in Explainable AI (XAI) in the AI and
Autonomy Lab,
School of Computing and Information Systems, The
University of Melbourne, under the supervision of
Tim Miller (primary supervisor),
Liz Sonenberg
and
Ronal Singh. My research interests include explainable AI,
human-computer interaction, human-centered decision
support and human-AI planning.
I apply mixed methods in my research by using machine
learning techniques, designing/conducting behavioural
experiments and doing qualitative/quantitative data
analysis. My skills include (1) Python, PyTorch,
Scikit-learn, Pandas, (2) machine learning/reinforcement
learning techniques, (3) high performance computing (HPC),
(4) building web-based applications for human-AI
interaction.
My PhD research focuses on building AI-assisted decision-making systems by explaining model uncertainty and developing a more reliable decision-making model that can reduce reliance on AI.
My research have been applied in various application domains, such as economics and healthcare, including supporting skin cancer diagnosis.
