About me

Johanne Trippas is a Postdoctoral Research Fellow at RMIT University, Melbourne.

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.

Article: The Search for Diversity in Tech

Johanne Trippas learnt about more than just computer science during her PhD: she also came to appreciate how technology impacts lives and why women need to be a part of it.

Article: Teaching search engines to know what you need

Information scientists are figuring out how to make search engines better at listening, so they can give us search results before we even ask.
