I currently work on as a Postdoctoral Research Fellow on Intelligent Systems, in particular, on next-generation capabilities for digital assistants including spoken conversational search and task progression through ubiquitous sensing.
My main research interests are Conversational Systems, Human-Computer Interaction (HCI), Interactive Information Retrieval (IIR), and
experimental design (both qualitative and quantitative), with the
aim in making information accessible to everyone.
I completed my PhD in Computer Science focussing on Conversational Systems at RMIT University in 2019 under supervision of Professor Lawrence Cavedon, Professor Mark Sanderson, and Doctor Damiano Spina.
I teach subjects such as Usability Engineering and User-centered
Design at both undergraduate and postgraduate level.
I am appointed as an ACM SIGIR Student Liaison,
feel free to contact me with questions about SIGIR-student matter.
