Development of a Picture-Identification Software Tool for Collecting Social Network Data

This pilot project entailed the development of a new social network data collection software tool called Netriks. The new version of the tool was successfully completed and is capable of capturing...

Networks Can Be Used to Analyze the Genomes of Humans and Model Organisms

Soon, sequencing one’s genome may become as commonplace as getting an X-ray. Consequently, personal genomes will increasingly serve as the lenses through which the public views biology....

Social Networks Help Explain Gun Violence

Tragic acts of violence like the Sandy Hook shooting in Newtown, CT, or the slaying of 15-year old Hadiya Pendalton in Chicago, IL, redirect political and public attention towards gun violence. And,...

Understanding Networks of Neurons in the Primate Brain

Networks, Institutional Transformation, and Emergence

Social networks are fluid and interstitial social objects. When social networks link otherwise distinct social groups, they often fundamentally transform those groups and the societies they are a...
