Work
In 2007, he proposed a solution to the
generalized valued blockmodeling by introducing
homogeneity blockmodeling with the basic idea "that the inconsistency of an empirical block with its ideal block can be measured by within block variability of appropriate values". The newly-formed ideal blocks, which are appropriate for blockmodeling of valued networks, are then presented together with the definitions of their block inconsistencies.
He also (in 2007/08) developed an
implicit blockmodeling approach, based on previous work of
Batagelj and
Ferligoj (2000).
In 2014, he proposed a new approach to the
blockmodeling
