LEXINGTON, Ky. (Aug. 21, 2026) — A citation begins with another scholar finding something useful: an idea that reframes a question, a method that makes new analysis possible or a finding that opens another line of inquiry.
Repeat that process 100,000 times, across disciplines and over several decades, and it begins to describe the reach of Steve Borgatti’s work.
Borgatti, Gatton Endowed Chair of Management and University Research Professor at the University of Kentucky Gatton College of Business and Economics, has reached 100,000 citations on Google Scholar. The milestone places him among a small group of scholars whose work has become foundational well beyond their home disciplines.
For colleagues who have watched the modern field of social network analysis take shape, the number confirms something they have understood for years.
“Steve is an absolute legend who has played a key role in the rise and spread of the field,” said Ajay Mehra, Chellgren Endowed Chair in Corporate Strategy and director of Gatton College’s LINKS Center for Social Network Analysis. “The reach of his ideas has been deep and wide-ranging, resonating with scholars across a mind-boggling array of disciplines.”
Borgatti’s research focuses on the relationships that connect people, groups and organizations—and on the structures those relationships create. His scholarship has helped researchers examine how information travels, where influence resides, why some individuals occupy advantageous positions and how patterns of connection shape collaboration and performance.
He has contributed to both the theory and the practical tools of network analysis. His work includes influential research on centrality, brokerage, knowledge sharing and organizational networks, as well as methods researchers use to study those subjects.
He is also the author of UCINET, widely used software for social network analysis, and Anthropac, a program developed for the analysis of cultural-domain data. Those tools helped make sophisticated network and field-research methods available to a much broader community of scholars and practitioners.
“The world of organizational network research, which is now a vibrant area involving a vast number of researchers and practitioners from around the globe, is based in the work of the Big Five thought leaders that emerged in the 1980s,” said Joe Labianca, a former Gatton management professor who is now at the University of Massachusetts Amherst. Borgatti, he said, helped create “the research infrastructure in terms of the measures that we use” and advanced the view of organizations as systems of relationships rather than structures visible only on an organizational chart.
“Steve has a rare gift for turning abstract mathematical structure into something researchers could actually see and use, for showing us that a matrix of numbers could reveal the shape of a friendship, a market, or an organization. That gift became a habit of mind for an entire generation of us,” said Giuseppe Soda, Bocconi University.
Citation counts offer an imperfect measure of scholarship. They do not capture every form of influence, and they vary greatly across fields. At this scale, however, the number provides a window into how often Borgatti’s work has informed the research of others.
His ideas have traveled well beyond management and organizational studies. Scholars in anthropology, sociology, public health, education, national defense and other fields have used his theories and methods to study problems in which relationships matter.
Dan Halgin, associate professor of management at Gatton College, said the breadth of Borgatti’s contributions is as striking as the total itself.
“Steve has shaped the field of social network analysis through his development of network theory and his work clarifying the theoretical foundations of network structure and position,” Halgin said. “A common thread running through all of his work is the combination of theoretical clarity and methodological elegance.”
That combination has helped researchers study subjects ranging from employee knowledge exchange and organizational performance to disease transmission and supply chain relationships. Borgatti’s work has also clarified some of the field’s most widely used concepts, including how scholars identify central or influential actors within a network.
“Crossing the 100K threshold puts Steve in an exceptionally exclusive club, one whose membership is based not on invitation, but rather on merit and scholarly impact,” said Bill McEvily, who will join Gatton College’s management faculty in January 2027. “The study of networks would not be what it is today without Steve’s body of work.”
Borgatti’s influence is not limited to published research. His peers repeatedly point to the time he has invested in building the scholarly community around social network analysis.
That work has included developing software, teaching researchers how to use network methods, serving journals and helping sustain the professional structures through which a growing field shares knowledge.
David Krackhardt, professor at Carnegie Mellon University and one of the early leaders of modern social network analysis, has known Borgatti since Borgatti was a graduate student in the 1980s.
“It’s hard to imagine the field without him,” Krackhardt said. “What has always stood out to me is how generous Steve has been—with his ideas, the software he created, his time, and by taking on the organizational work that keeps a field and its institutions thriving.”
Ronald Burt, professor at the University of Chicago and Bocconi University, similarly described Borgatti’s contribution in personal as well as scholarly terms.
“On a score profile of integrity, intuition, skill and charitable contribution to colleagues, he has no peer,” Burt said. “The man is to us a unique gift.”
Martin Kilduff, professor of organizational behavior at University College London, first encountered Borgatti’s scholarship when Borgatti was completing his doctoral work at the University of California, Irvine. He recalled being struck by research that brought anthropology and network analysis together.
“Steve has illuminated many aspects of the social network world for us over the years,” Kilduff said. “No need to stop at 100K citations.”
Research with a continuing reach
Borgatti joined the University of Kentucky in 2008 and holds appointments in Gatton College’s Department of Management and LINKS Center for Social Network Analysis. His selected publications include work in journals such as Science, Management Science, Organization Science, Journal of Management and Social Networks.
Among his best-known contributions is “Network Analysis in the Social Sciences,” published with Mehra, the late Daniel Brass and Labianca in Science in 2009. His other influential work has examined centrality and network flow, information seeking and learning within organizations, core-periphery structures and the growing network paradigm in organizational research.
His research remains active. Recent work has addressed subjects including network dynamics in organizations, gender and citation patterns, social media networks and the structure of networks with overlapping group memberships.
Borgatti has also carried that scholarship into the classroom. Mehra said his standing as a researcher has never diminished his commitment to students.
“Steve also takes teaching very seriously and shines in the classroom,” Mehra said. “He has made a difference in the lives of many cohorts of Kentucky students since joining us here in 2008.”
That combination—developing ideas, creating tools, teaching others to use them and helping a scholarly community grow—helps explain why Borgatti’s work continues to be cited across such a wide range of disciplines.
The 100,000 citation milestone measures one part of that legacy. The larger record can be found in the questions other researchers have been able to ask, the methods they have been able to use and the fields that now see relationships and networks differently because of his work.
