Patrick Doreian is an American mathematician and social scientist, whose specialty is network analysis.
His specific research interests include blockmodeling, social structure and network processes.
[4] With Norman P. Hummon in 1989, he proposed a main path analysis, a mathematical tool,[5] to identify the major paths in a citation network, which is one form of a directed acyclic graph (DAG).
In 1994, with Vladimir Batagelj and Anuška Ferligoj, he introduced the generalized blockmodeling.
[6] His co-authored book Generalized blockmodeling (with Vladimir Batagelj and Anuška Ferligoj), was in 2007 awarded the Harrison White Outstanding Book Award by the Mathematical Sociology Section of American Sociological Association.
