Yong-Yeol Ahn, PhD: Finding Hidden Structure in Complex Networks



Our life relies on various complex systems: the intricate mechanisms of our bodies, social systems in our society, and many more. The basic structure of these complex systems can often be described as a network that consists of individual elements and the interactions between them. For example: interacting genes, proteins, and metabolites form biological networks; interacting neurons form a brain network; and interacting people form a social network. In this talk, I will overview why the science of networks matters, discuss a fundamental topic called “network communities”, and introduce an application of network science to our culinary practices.


Yong-Yeol Ahn joined Indiana University School of Informatics and Computing as an Assistant Professor October 2011.

He earned his Ph.D. in physics from KAIST in 2008.  He was a postdoctoral researcher at the Center for Complex Network Research of Northeastern University and a visiting researcher at the Center for Cancer Systems Biology at Dana-Farber Cancer Institute from 2008 till 2011.  He is interested in various complex systems such as biological and social networks.
