About me

Johanne Trippas is a Doreen Thomas Postdoctoral Fellow at The University of Melbourne, Australia.

I am a Postdoctoral Fellow interested in Intelligent Systems, in particular, on next-generation capabilities for digital assistants including spoken conversational search, collection of complex datasets and task progression through ubiquitous sensing. I am also working with Ambulance Victoria, using artificial intelligence (AI) to efficiently identify cardiac arrest emergency calls to accelerate critical care and spare lives.

My main research interests are Conversational Systems, Human-Computer Interaction (HCI), Interactive Information Retrieval (IIR), and experimental design, with the aim of 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 am awarded the RMIT University Deputy Vice-Chancellor’s Higher Degree by Research Prize for my doctoral work and thesis.

I am appointed as Vice-chair of the ACM SIGIR Artifact Evaluation Committee (AEC) promoting the reproducibility of research results.

Article: Hey Siri, how’s my mental health?

Conversational systems may play a key role in future mental healthcare and have the potential to help cut down global e-waste – but there are caveats. By Dr Johanne Trippas



Article: What do pilots think of having more AI in the cockpit?

Pilots are keen to explore using new technology like digital voice assistants in the cockpit but they also need to be central in the design of any new systems. By Dr Fabio Mattioli, Dr Johanne Trippas, Sarah Gosper, Dr Fraser Allison, Sara Khorasani, Dr Harriette Richards, Cynthia Sear and Gabby Bush



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.
