SOCIAL NETWORK ANALYSIS

My research focuses on Social Network Analysis (SNA) on online communities, especially Free/Libre Open Source Software Development (FLOSSD) communities. I am currently working on a project that focuses on analyzing online communications of online FLOSSD communities, particularly the ones that have forked, to identify common measures in such complex networks. Temporal visualization of these complex communication networks over time is another focus of the project which aims to array disparate information to make sense of the underlying structure and dynamics of such social networks.
