About me

I’m a research scientist at Yahoo! Labs’ Mobile Sensing and User Behavior group in Sunnyvale, California.

On a very general level, I’m interested in how people perceive technologies and integrate them into their daily lives. My research revolves around mobile location-based services and people’s perceptions of their surroundings, ‘Research in the Large’: using wide distribution channels and existing services for research purposes, and people’s perceptions of applications and ‘things’ that use data around -or about- them to adapt and personalize themselves. My user studies combine quantitative and qualitative methods to understand both what is happening, and why; grasping the human-scale motivations behind the web-scale data.

Before I joined Yahoo! in Nov 2012, I was a senior researcher and project leader at the Mobile Life Centre in Kista (Stockholm), Sweden where I led Mobile Life’s Mobile 2.0 project and activities of SICS within the European LIREC project on human-robot interaction.

Keywords: mobile interaction, personalization & context-adaptation, location-based services, urban informatics, instrumentation & data quality, services as design materials, interaction with (semi-) autonomous ‘things’, user control, trust and situated user experiences.

Introducing Phobot to Barbapapa

I have a PhD from the Human-Computer Studies lab at the University of Amsterdam (April 2010). My dissertation focused on user interaction with user-adaptive and semi-autonomous systems and involved user studies to gain more insight in user behaviour, social-affective reactions and trust. My studies involved interaction with personalised recommenders and information filters, mobile devices and human-robot interaction.

Some of my personal interests include photography, dancing (Lindyhop/Swing), electronica, and spending time in tents amidst lots and lots of summer festival noise.
