## Education and career

Vladimir Batagelj completed his Ph.D. at the University of Ljubljana in 1986 under the direction of Tomaž Pisanski. He stayed at the University of Ljubljana as a professor until his retirement.

His work has been cited over 11000 times.
His book *Exploratory Social Network Analysis with Pajek*, coauthored with Wouter de Nooy and Andrej Mrvar, is Batagelj's most cited work and has over 3300 citations. The book was translated into Chinese and Japanese. The revised and expanded third edition has been published by Cambridge University Press[2].

He is particularly known for his work on *Pajek*[3], a freely available software for analysis and visualization of large networks[2].
Batagelj began work on Pajek in 1996 with Andrej Mrvar, who was then his PhD student.

In 1975, 11 years before completing his PhD, Batagelj published a solo paper[4] in Communications of the ACM[2].

Batagelj authored more than 20 textbooks in Slovenian, covering topic like TeX, combinatorics and discrete mathematics[2].
He has also written extensively in the Slovenian popular science journal *Presek*[5].

## Awards and honors

- In 2007 the book
*Generalized blockmodeling*was awarded the Harrison White Outstanding Book Award by the Mathematical Sociology Section of American Sociological Association[9] awards.pdf. - In 2007 he was awarded (together with Anuška Ferligoj) the Simmel Award by INSNA[10].
