Stijn Verstichel, PhD
Senior Researcher

Stijn obtained his PhD in 2011 on the topic of distributed reasoning for context-aware services. Since then he has been a post-doctoral researcher, performing research on semantic technologies applied in a variety of domains, such as eHealth, wireless senor networks and transportation as well as being involved in the follow-up of bachelor's and master's courses at the Faculty of Engineering and Architecture of Ghent University. 

If you can't reach Stijn on his mobile, you might want to look for him in a basketball gym somewhere in Europe, satisfying his second love as FIBA table official, or even in his second (wannabe) home country - the UK.

Bram Steenwinckel, PhD
Post-doc

Bram his research tries to improve anomaly detection, and root cause analysis for the eHealth and predictive maintenance domain, using (semantic) knowledge models in combination with both black and white-box machine learning techniques. He defended his PhD in 2023 on "knowledge graph creation and embedding to realize explainable hybrid AI applications", which can be found here. As a post-doc he continues this research, mainly applied to chronic disease management and predictive maintenance. 

Besides his research, Bram likes to talk about sports as well. More specific his hobby: Volleyball and oh, he's a big Coldplay Fan.

Mathias De Brouwer, PhD Post-doc

Mathias performs research in the areas of stream reasoning & cascading reasoning. More specifically, he tries to make the semantic reasoning on data streams in complex IoT contexts more efficient by exploiting resources in the edge of IoT networks, and by adaptively deriving the necessary stream processing queries in a context-aware fashion. His research is mostly applied in the context of health care use cases, such as ambient-intelligent smart home monitoring. He defended his PhD in 2023 on "Adaptive semantic stream reasoning for healthcare". As a post-doc he performs research on semantic reasoning and project management on behavioral monitoring apps, cloud and dynamic dashboards for health. 

If Mathias is not working, chances are high he'll be traveling around somewhere on our planet. If not, he might be found in his couch watching sports, or in his kitchen baking his newest cake creation.

Kyana Bosschaerts
PhD Student

Kyana’s research is centered around digital interventions for behavioral change. She develops a chatbot to act as a personalized coach to support behavior change. In her research, the focus is on smoking cessation.

Aside from developing behind a computer, Kyana likes to run three times a week. Hiking in the mountains and woods is the ultimate travel experience, but cultural places fascinate her too. Before she even realizes it herself, she gets lost in a fantasy world, through any media whatsoever: books, manhwa, manga, anime, donghua, movies, kdramas, and tv shows. As long as it takes you on a trip, count her in!
