Research

I invest most of my research energy into Avalanche, a project that I ramped up within the Systems Group here at ETH. In Avalanche, I look at how modern hardware technologies can be used effectively to accelerate or otherwise improve database processing. For instance, the Glacier query compiler that I built together with René Müller and Louis Woods takes advantages of the potential offered by field-programmable gate arrays (FPGAs) and applies that in a data streaming context; our hardware-accelerated solution to the frequent item problem significantly outperforms all existing (software) solutions.
The success of Avalanche has been acknowledged by the Swiss National Science Foundation, which sponsors me with one of the prestigious Ambizione grants for young researchers.

The transport mechanisms offered by modern network cards that support remote direct memory access (RDMA) significantly shift the priorities in distributed systems. Together with Philip Frey, I developed the RDMA-part of Data Cyclotron, a research effort that I work on jointly with the database group at CWI Amsterdam. Based on a simple ring-shaped topology and an RDMA-accelerated network, Data Cyclotron offers ad-hoc querying over data of arbitrary shape and arbitrary size.

Much of my past research work has revolved around the Pathfinder XQuery compiler. Pathfinder compiles expressions from the W3C XQuery language into a text book-style relational algebra, enabling traditional relational database back-ends to operate as high-performance XQuery processors. Pathfinder is distributed as MonetDB/XQuery, together with its primary database back-end MonetDB. In addition, Pathfinder provides support for SQL:1999-compliant databases, as well as for the commercial main-memory database kdb+.
