I have worked with many research groups within our faculty and I find it excellent that there is always somebody to ask if I need new knowledge about any computer science related issue, and any other matter I might add. My current research unit is in the Faculty of Information Technology and Electrical Engineering, find our pages: Center for Ubiquitous Computing where I lead the Interactive Edge research group. In research, enabling situation awareness is my job and I utilize different kinds of sensor networks that produce data for this.I design data collection, participate in sensor installations, collect and store data, clean the data and draw conclusion from selected features utilizing machine learning and data fusion methodologies. I am also interested in solving the not-so-technical barriers of leveraging artificial intelligence - regulatory, ethical restrictions and possibilities but also how can we enhance the digital skills and AI literacy of people.

    Interactive Edge Research Group (iEdge)

    Our research focuses on adaptive, reliable, and trusted edge computing. Edge computing distributes applications between the cloud, data producing devices, and devices at the edges of wireless and fixed networks. This computing paradigm promises more bandwidth, reduced latencies, and more control on data access and consent management. Edge computing brings AI methods closer to the physical environment. This enables deep integration of AI with applications supporting humans in their activities and with machines to realise autonomous systems. AI is integrated with the edge computing platform as well, for example, to decide optimal locations for computations.We study situation-aware, self-organizing and self-managing software platforms that use efficiently edge computing infrastructures for 5G and beyond. We enable trust with distributed ledger technologies and privacy-by-design methods. We push edge computing to the limits by embedding computations and AI into physical objects that are digitally fabricated to fit to their purpose. We use distributed artificial intelligence, big data tools, and machine learning methods to explore situation awareness for both end-user applications and the edge computing platform. We implement AI methods in ethical manner and emphasise testing in real environments. We expect our research to shed light on how humans can benefit from edge computing and how it can be used to realise resource-efficient systems.
