I am a human-computer interaction (HCI) and UbiComp researcher with a background in Cognitive Science. I am a tenure-track researcher at Centrum Wiskunde & Informatica (CWI), within the Distributed & Interactive Systems (DIS) group. Previously, I did my Postdoc at the HCI Oldenburg lab, part of the Media Informatics and Multimedia Systems group at the University of Oldenburg / OFFIS (Germany). I received my PhD in Computer Science from the University of Amsterdam (Netherlands), working at the Information and Language Processing Systems (ILPS) group.
My research focuses on people-centric pervasive sensing. My work ranges from developing sensor-based tracking technologies for behavior change, investigating core usability issues in mobile 3D gesture based interaction across domains, understanding mapping and GPS failures in the developing world, mining large-scale social media traces (e.g., Flickr, Twitter) for behavioral insight, to using computer vision techniques to enable more natural mobile interaction.
Research Interests:
- Affective computing
- Wearable sensing & behavior prediction
- Human activity recognition
- Social media data mining
- Urban mobility and interaction
