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.
