My general areas of interest include transformations of the media system, political and civic participation, and the social aspects of Internet technologies. I’m currently exploring applications of network theory and methodology to media studies problems. My dissertation at USC Annenberg takes a network perspective to the study of inter-media agenda-setting in an era of fragmentation. Issue overlap patterns across media outlets and sectors are used to evaluate the effects of specific factors (ownership, media format, news values, market forces, political ideology, etc.) on news agenda homogeneity. The study looks into the implications of network properties for the influence flow across outlets. Nationally representative data about US news consumers are further used to investigate the structure of individual media preferences.
Some of the statistical software packages I use include R, SPSS, LISREL & PRELIS, and AMOS.
The network analysis & visualization tools I’ve worked with include Pajek, UCINET, PNet family, Siena/RSiena, Statnet, iGraph, Network Workbench, LexiURL, WordIJ, NodeXL, Gephi, and Visone.
