I work on query processing in databases, and the use of artificial intelligence to boost database performance. Regarding the application of databases, I investigate the potential of collecting the queries first and then derive the database design from them.
Research projects
Query-driven database design, integration, and optimization
Using modern hardware (FPGAs) to speed up database-query processing
Investigate AI methods for the improvement of database technology (e.g. autoencoder)
Build a repository of neural-ne
