Social Network Analysis


Social network analysis is a technique that goes beyond sociology to influence everything from network science more generally, to epidemiology, to systems theory approaches throughout medicine.

The REACH Lab has advanced epidemiological science through the creation of the MABUSE simulation platform, a large agent based network simulator capable of modeling HIV and HCV co-infection dynamics across multiple network layers, and across a range of risk scenarios. More recently we have begun work on two network data collection techniques using smart phones on the one hand (ODIN), and tablet devices on the other (SNAPT). Together, these new software implementations will significantly improve social science network data collection in the field.
