About me

I am a PhD candidate in Computer Science at RMIT University, Melbourne.

I finished my Masters in Computer Science at RMIT University in 2014. My main research interests are Human Computer Interaction (HCI), Interactive Information Retrieval (IIR), and experimental design (both qualitative and quantitative), with the interest in making information accessible to everyone.

I am currently a PhD candidate in Computer Science at RMIT University working with Associate Professor Lawrence Cavedon, Professor Mark Sanderson and Doctor Damiano Spina in Spoken Conversational Search.

My are of research is on how we can present search engine results over a speech-only communication channel without overwhelming the user with information. I am also interested in how conversations can be structured between the user and the Spoken Conversation Search System.
My focus is on the experimental design with multi method analysis as evaluation.

I am teaching subjects such as Usability Engineering and User-centered Design at both undergraduate and postgraduate level.

I am appointed as a ACM SIGIR Student Liaison, so feel free to contact me with questions about SIGIR-student matter.
