Social Network Analysis (SNA)
Kate is Senior Technical Staff Member in the Collaborative User Experience group at IBM Research where she uses Social Network Analysis as a research and consulting tool to gain insights into patterns of collaboration in distributed teams. She has used SNA with over 60 groups covering team dynamics, knowledge and information flow, collaboration, communities, innovation, software development and governance structure. She is currently investigating the systematic combination of social and task networks to effect more productive and efficient collaboration and coordination in distributed software teams. Kate has published academic papers on her research using SNA in the CHI, CSCW, software engineering and management science premier conferences.
Kate originally joined Lotus in 1993, where she led research and consulting on expertise location and the role of intermediaries in knowledge transfer. She returned to IBM in 2003 after spending several years as Global Solution Lead for collaboration at Viant, a professional services organization and as a visiting scholar at the Harvard Graduate School of Education.
Kate has a B.Sc in Psychology from the University of London and a PhD. in Cognitive Science from the University of Sussex, UK. She did post-doctorate work in cognitive science at University of Texas, University of Massachusetts and Yale. Kate has been active in several professional societies including the ACM SIG on Human Computer Interaction including founder of the Boston chapter and conference co-chair. She has co-chaired other professional and business conferences and she serves on the review committees of conferences and journals in CHI, CSCW and software engineering.
