• MoWe: Mobile Wellness September 2010 - August 2011, Stockholm (Sweden)

  MoWe investigated the use of mobile mashups to aggregate and visualize multiple well-being sensors and data with different time scales and how these data streams can be presented to encourage interaction, increased awareness and positive behavior change.

  The project developed a mobile mashup platform for mobile health and well-being that was tested in the field with two users groups (10 participants) in Stockholm and Chicago for a 10 week period.

  The platform provided aggregation of data and analytics across multiple sensors and context. From this, we produced a set of significant correlations and deviations which were displayed to the user in a feed on a mobile phone widget and through a website.

  In this project I was in charged of the backend development as well as the mobile web interface. Additionally, I was involved in the design, interviews and data analysis of the results using a grounded theory based affinity analysis.

  
• Melange February 2011 - July 2011, Stockholm (Sweden)

  Given the adoption of mobile data services of the last couple of years, evaluating the potential benefits of context-aware content delivery schemes, in terms of network and terminal resource utilization, together with user service perception (QoE), is of paramount importance for the success and sustainability of providing future data intensive services in cellular networks.

  Melange was a novel approach for evaluating service provision in cellular networks in a testbed oriented living laboratory setting. Its goal was to identify, test and evaluate key indicators affecting QoE and QoS for mobile services and networks under real scenario conditions.

  I was the lead developer of this project. The platform was built using Ruby on Rails on the backend and an Android mobile application client. These components were glued together using the Google Cloud to Device Messanging Server (C2DM).

  
• Food marketing towards children in India April 2011 - May 2011, Vellore (India)

  Food marketing targeting children constitutes an important risk for overweight and non-communicable disease. In this study we assessed exposure to marketing of unhealthy food products and its effects on children aged 3-13 from different socioeconomic backgrounds in southern India.

  We recruited 306 child-parent pairs at a pediatric clinic in the Christian Medical College. We developed a test including 18 brand logos assessed logo recognition ability and an indicator for marketing exposure using an graphical tool that I developed for Android tablet devices. Information about children's food preferences, nutritional knowledge, weight and height was obtained. Finally, a parental questionnaire collected information on children's socioeconomic characteristics, eating and purchase requesting behavior.

  
• MIT Media Lab: Health and Wellness Innovation 2011 January 2011, Boston (USA)

  I was a participant in the Health and Welness Innovation 2011 workshop. The workshop was organized by the New Media Medicine group of the MIT Media Lab.

  As the population ages and the burden of chronic disease grows, there is a pressing need for technology to improve the delivery of healthcare and to help individuals to take greater control of their health and wellness. Hence, the focus of the workshop was to innovate in the areas of chronic disease management, disease prevention, healthy habit formation, and psychological and social wellness.

  As a result, We extended Indivo, a personal health records system, in order to support rich queries of time-series data such as pedomenter or heart-rate information. Using this, we created a watch interface that allows a person to see if they are ahead of or behind their step count goals for the day and another visualization that showed a radial progress bar of steps taken towards a goal.

• The Future of Talent January 2010, Ahmedabab (India)

  I was a member of The Future of Talent, a Think Tank in India organized by the National Institute of Design of Ahmedabad and the Stockholm School of Entrepreneurship.

  The thesis of the think tank was that many talent management systems misses that talent derives not from single individuals, but from groups of individuals with varying competences and skills i.e. an Interdisciplinary Team. The interdisciplinary settings result in talented and dynamic transactions and in the creative economy we must therefore combine talent with an interdisciplinary perspective.

  Interdisciplinary work groups were setup to discuss the topic from different perspectives and field trend spotting trips on the city of Ahmedabad, India, were carried out. Part of the final result of these work groups was a video report of the findings.
