As part of her PhD research, Sandra developed new interaction techniques for emerging PIM systems and at the same time to offer mechanisms for digitally augmenting a user's existing organisational structures (e.g. piles of papers) in order to guide and help users in managing and re-finding their physical and digital information items. Additionally, she investigated how context awareness can be integrated in PIM systems from a user-centric viewpoint. By providing a unified perspective on our personal information space and by including a context-aware component, she developed a solution to help users in keeping, organising and re-finding their information which provides the right personal information at the right time and across physical and digital information spaces.
