Main contributions to science, in inverse chronological order:
Contribution 5: Braingraphs
We created the first consensus graph server (the Budapest Reference Connectome Server) [6,1]; we proved that women’s braingraphs had better connectivity properties than that of the men [2,5,8] at the first time in the literature. We have mapped the differences in the individual variability of the braingraphs in lobes and in smaller brain areas , also first in the literature. We also have recognized – first in the literature – that most probably there is a close connection between the number of occurrences of a certain edge in the braingraphs of different subjects and the time of its development [4,9,10,12]. We have shown that the women’s advantage in brain connectedness is due to sex, and not to the size of the brain . We have made hundreds of braingraphs, computed by us, available for the community . We have published hundreds of high resolution directed connectomes , first in the literature. In  we have shown the robustness of the Consensus Connectome Dynamics (CCD) phenomenon, and we have also given a probabilistic simulation that well-approximates the CCD phenomenon, also first in the literature.

Contribution 4: PageRank-based protein network analysis
We have applied the PageRank of Google for the evaluation of protein-protein interaction networks, and introduced a modified version (the PageRank, divided by the degree of the node) [1,2,3] that is capable of identifying low-degree important network nodes.

Contribution 3: Data-mining in large biological databases and molecular modeling
We applied data-mining methods for making discoveries in large biological databases. The discoveries involved protein 3D structure analysis [1,2,4], the construction of the new protein-docking tool „Frigate” , the construction of the Metagenomic Telescope , and the identification of giant viruses in desert environments [5, 9]. In  we have shown that only four (spatial) points in the 3D structure of the large family of serine proteases determine the function of the enzyme in question.

Contribution 2: Extremal set systems modulo composite numbers and their applications
We have falsified a longtime conjecture of Frankl through a construction of mod 6-restricted intersection set systems , and found numerous applications [2,3,4] for that surprising construction, involving very fast matrix multiplication and a very dense coding method, called „Hyperdense coding” .

Contribution 1: Multiparty communication complexity and circuit complexity
