I am a Senior Principal Research Scientist at the HCI & Visualization Group at Autodesk Research in Toronto, Canada. My research interests lie at the intersection of Human–Computer Interaction, Ubiquitous Computing and Information Visualization. At Autodesk, I am focusing particularly on research in HCI and Software Learning.

I'm broadly interested in addressing interaction challenges with non-traditional interactive technologies, and particularly in designing technology that puts people back in control of their digital environments. My research has included topics such as making ubiquitous computing and context-aware technologies intelligible or understandable (and how that relates to explainable AI); the design principle feedforward; addressing interaction challenges and dark patterns in proxemic interactions; situated visualization; and facilitating the design and development of multi-device and cross-device user interfaces. For more details about my work, have a look at my list of publications or my Google Scholar profile.

My research has received a number of awards. My PhD dissertation was awarded with the 2015 FWO - IBM Innovation Award; this award is given annually to the best Belgian PhD dissertation in computer science. My papers have received awards at premier Human–Computer Interaction conferences, including a Best Paper Award at DIS 2014 and a Best Paper Honorable Mention Award at CHI 2013.

Before joining Autodesk Research, I was an Assistant Professor at the Department of Computer Science at Aarhus University (2017–2020). Prior to that, I was a Postdoctoral Fellow in the Innovations in Visualization Laboratory at the Interactions Lab at the University of Calgary (2016–2017), where I worked with Sheelagh Carpendale. Before that, I did a postdoc with Russell Beale at the HCI Centre of the University of Birmingham (2015), working on mobile and context-aware technology and behaviour change intervention technologies. I received my PhD in Computer Science in December 2014 from Hasselt University, working with Kris Luyten and Karin Coninx in the EDM HCI group.


Survey on Situated Visualization Accepted at VIS 2021

April 2021

Our paper "What's the Situation with Situated Visualization? A Survey and Perspectives on Situatedness" has been accepted to IEEE VIS 2021. In this paper, we review the literature on situated visualization. We found that the majority of work in situated visualization to date is technology-centric and foregrounds a spatial understanding of situatedness. We contribute five perspectives on situatedness (space, time, place, activity, and community) drawn from prior developments in HCI that together expand on the prevalent notion of situatedness in the corpus, which we illustrate through six case studies.

Paper on QUBI Accepted at DIS 2021

April 2021

Our paper "Machine Body Language: Expressing a Smart Speaker’s Activity with Intelligible Physical Motion" has been accepted to DIS 2021. In this paper, we explore whether we can imbue smart technologies with machine mannerisms. We present QUBI, a smart speaker with expressive physical motions to complement its conversational interaction and make its activities intelligible.

Paper Accepted at OZCHI 2020

October 2020

Our paper "Intelligibility Issues Faced by Smart Speaker Enthusiasts in Understanding What Their Devices Do and Why" has been accepted to OzCHI 2020. From an online survey and interviews with smart speaker enthusiasts, we identified seven breakdown recovery strategies and found that enthusiasts particularly struggled to understand breakdowns in their IoT infrastructure. From our findings, we suggest three future research directions: infrastructural breakdowns as learning opportunities; leveraging non-verbal communication; and considering the intelligibility needs of passive smart speaker users.

We found that overall, the impact is effectively negligible for practical applications.

Paper Accepted to DIS 2018

March 2018
