I am associate professor at the Faculty of Computer Science of the Free University of Bozen-Bolzano (FUB). I received a M.Sc. degree in CS from the TU Vienna (1989) and a Ph.D. degree in CS from the RWTH Aachen (1996). My research interests focus on database technologies for processing temporal and spatial data, data warehousing and analytics, and approximate query answering. The adopted research methodology combines fundamental research, system development, and empirical evaluation. The research problems originate from different application areas, such as government, tourism, health-care, and agriculture.
The Temporal RDBMS project aims at extending RDBMs with full-fledged support for querying interval-timestamped data. The basic idea is to reduce the temporal operators to the non-temporal counterparts with the help of two primitives. Our solution is implemented in the kernel of PostgreSQL. [more]
In the DASA project we aim at developing solutions for managing/analysing time series data coming from weather stations in agriculture. Specific research problems include the imputation of missing values and the search for similar time series or episodes in time series (e.g., most similar Summer). [more]
The Isochrones project aims at studying isochrones as a tool for reachability and catchment analysis in spatial network databases. [more]
