Research interests:

My interests focus on applications of logic to computer science, including:

I am currently working on Bounded Set Theory and computability over sets thereby developing a set theoretic approach to querying (nested, complex) databases, in particular Web like (semi structured) databases by using an anti-founded version of BST with the possibility of arbitrary cycling in the membership relation. The latter roughly corresponding to hyper-links between Web-pages. This is also related to descriptive complexity and finite model theory. E.g., the typical result says that queries definable in a set theoretic language are exactly those computable in polynomial time.

My other interests concern bounded and feasible arithmetic, including intuitionistic one (with corresponding realizability approach). Formerly I worked and still am interested in lambda calculus, domain theory, sequentiality and degrees of parallelism for finite type continuous functionals.
