I’m a research scientist at Yahoo in Sunnyvale, California.
My work revolves around better understanding of user needs and intent, to facilitate surfacing personalized & contextual content – while respecting user expectations in terms of transparency and social norms in the process (i.e. understand user’s priorities and needs, don’t get in the way, be transparent and don’t embarrass). This includes the effects of interaction and service design on user behavior. My research specifically focuses on people’s reactions to systems that adapt/personalize themselves to users and their (social) context.
I combine quantitative, controlled and in-depth qualitative methods to understand both what behavior is happening, and the underlying reasons why.
My projects at Yahoo have focused on:
On a very general level, I’m interested in how people perceive technologies and integrate them into their daily lives. My past 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.
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.
