Currently, I am an independent researcher in the area of hierarchical graphs, i.e. graphs which can be decomposed into or are created from modules which are reused several times in the hierarchy. I am interested in their representation, mathematical properties, their recognition and decomposition, and efficient algorithms for solving logical and quantitative problems on them.

The first step in the hierarchical graphs research is the open source HRDAG project used to decompose hierarchical graphs. This may be useful to reverse-engineer human constructs like electronic equipment, manufactured machines, or bureaucratic hierarchies; but also to decompose natural constructs like gene-relation or protein-relation nets.

I am also interested in Software/Hardware Formal Verification, Logic and Graph Theory, Finite Model Theory, and Graph Polynomials.


Education:

I hold M.Sc. (2008, Cum Laude) and B.Sc. (1996, Summa Cum Laude) from the Computer Science Department at the Technion - Israel Institute of Technology.

My M.Sc. thesis title: Regression Verification: Theoretical and Implementation Aspects , under the supervision of Prof. Ofer Strichman.
