'''Vladimir Batagelj''' (born June 14, 1948 in [[Idrija]], [[Socialist Federal Republic of Yugoslavia|Yugoslavia]]<ref name=slovbio>{{cite web|url=https://www.slovenska-biografija.si/oseba/sbi1003800/|title=Batagelj, Vladimir|website=Slovenska biografija (in Slovenian)|access-date=September 26, 2019}}</ref>) is a [[Slovenians|Slovenian]] [[mathematician]] and an emeritus professor of mathematics at the [[University of Ljubljana]].  He is known for his work in [[discrete mathematics]] and [[combinatorial optimization]], particularly [[data analysis|analysis]] of social networks and other large networks ([[blockmodeling]]).

==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, where he was a professor of sociology and statistics, while also being a chair of the Department of Sociology of the [[Faculty of Social Sciences, Ljubljana|Faculty of Social Sciences]]. As visiting professor, he was taught at the [[University of Pittsburgh]] (1990-91) and at the [[University of Konstanz]] (2002). He was also a member of editorial boards of two journals: ''[[Informatica (journal)|Informatica]]'' and ''[[Journal of Social Structure]]''.<ref name="gener-black">{{Cite book |last1=Doreian |first1=Patrick |last2=Batagelj |first2=Vladimir |last3=Ferligoj |first3=Anuška |title=Generalized Blackmodeling |publisher=Cambridge University Press |date=2005 |isbn=0-521-84085-6}}</ref>

His work has been cited over 11000 times.

His book ''Exploratory Social Network Analysis with Pajek'' on [[blockmodeling]], 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.<ref name=amc70>{{cite journal|url=https://amc-journal.eu/index.php/amc/article/view/1812/1272|title=Vladimir Batagelj is 70|journal=Ars Mathematica Contemporanea|date=2 October 2018|volume=15|issue=1|access-date=September 27, 2019|last1=Pisanski|first1=Tomaž}}</ref>

In 1975, 11 years before completing his PhD, Batagelj published a solo paper<ref name="Batagelj1975">{{cite journal|last1=Batagelj|first1=Vladimir|title=The quadratic hash method when the table size is not a prime number|journal=Communications of the ACM|volume=18|issue=4|year=1975|pages=216–217|issn=0001-0782|doi=10.1145/360715.360737|s2cid=15485469|doi-access=free}}</ref> in Communications of the ACM.<ref name=amc70 />

Batagelj authored more than 20 textbooks in Slovenian, covering topics like [[TeX]], [[combinatorics]] and [[discrete mathematics]].<ref name=amc70 />
He has also written extensively in the Slovenian popular science journal ''Presek''.<ref>{{cite web|url=http://vlado.fmf.uni-lj.si/vlado/refs/01467mar07.pdf|title=Vladimir Batagelj's publications 1967-2007|website=Vladimir Batagelj's homepage|access-date=September 27, 2019}}</ref>
