Co-authorship is one of the most tangible forms of research collaboration. A co-authorship network is a social network in which the authors through participation in one or more joint publications are linked (undirectedly) to each other. The present work used social network analysis to study co-authorship network of UPM journal publications database for the first four years of Research University (2007-2010) with the aid of Mathematica 11. The structure of the coauthorship network of publications between 2007 till 2010 was analyzed using the micro-level indicators such as degree centrality, closeness centrality, betweenness centrality and assortativity to observe changes of structure in the network over the early research university years. The study also determines the most connected authors and their influence among coauthors through comparison of their centralities. Community structure is another typical structure found in social networks. Using modularity approach, the community structures are analysed for each year’s co- authorship network and found that then fall naturally onto closely associated areas.
