Research Interests:

Identity Verification Systems:
The use of alternative human identification techniques (e.g. face and voice recognition) in order to increase the security of accessing critical resources. So far a demo system for mapping user names and passwords to real users to gain access to a workstation has been developed.

Data Mining & Knowledge Discovery: 
The research on data mining concerns the discovery of interesting patterns from large amounts of data. Particular focus is given to association rules discovery. Contributions so far include the development of an optimized association rules discovery technique and the implementation of a flexible framework used for testing and comparing different data mining algorithm implementations.
