Themes:

• Data and Knowledge

Interests

I am interested in query answering when there are conflicts in the database. In particular, I work with inconsistency-tolerant semantics in the ontology language of Datalog +/-. Understanding the complexity of existing inconsistency tolerant semantics and developing new more accurate semantics are my main interests. 

In addition to that, I am interested in optimisation problems and their theoretical study. 

Biography

I have obtained BA and MMath degrees in Mathematics at the University of Oxford. My master thesis "A Study of Weighted Clones" was awarded a Gibbs prize as one of the two best Mathematics master thesis at Oxford.
