In general, my research focuses on spatial algorithms for pervasive computing environments that anticipate, adapt, and respond to the needs of users. In my work I address a key research challenge: how to efficiently collect and process an abundance of heterogeneous, possibly imprecise data and how to transform it into useable information. The continuous collection of data with a high degree of spatial precision also holds privacy risks, and my research investigates privacy-aware algorithms that ensure high-quality location-based services without revealing the precise location or identity of a user accessing those services.
