Complex Networks and Systems

Are you interested in exploring and understanding how the parts of a system interact with each other to drive the behavior of the system as a whole, in areas as diverse as social networks, the human brain, a language, power grids, financial markets, or gene regulatory networks? The complex networks and systems (CNS) track may be for you.

When you study CNS, you’ll explore new solutions for problems in computer science, physics, math, biology, health, and cognitive and social sciences. You might determine what makes a certain YouTube video go viral, examine Instagram data to discover adverse reactions caused by drug interactions, or develop a model that can accurately predict the spread of misinformation online.

The complex networks and systems track includes:

Training in this track is consolidated and enhanced by the Center for Complex Networks and Systems Research ( CNetS) and the Center for Social and Biomedical Complexity ( CSBC).

See how the National Science Foundation Research Traineeship (NRT) award to Indiana University will address a growing need with an integrated dual PhD program that trains students to be "bidisciplinary" in Complex Networks and Systems (CNS) and another discipline of their choosing from the natural and social sciences.

Description of the video:

00:00 [Music]
00:06 NRT are the top graduate education
00:09 programs at the National Science
00:10 Foundation funds we have been here at
00:13 Indiana University training PhD students
00:16 for over 14 years in complex networks
00:19 and systems in network science and
00:20 complexity I was attracted to the
00:23 program by the opportunity to work with
00:25 such a diverse group of students and
00:28 faculty who had all kinds of interests
00:30 but were united by a common desire to
00:33 study complexity one of the big
00:35 advantages for students in this program
00:37 is that they can pair their interesting
00:39 and complex networks and systems but yet
00:42 deep in training into another area
00:45 merging this complex systems informatics
00:47 approach with the like cognitive science
00:50 approach which is my other field we had
00:52 a lot of sense in terms of what I want
00:53 to research they gave me an option to
00:55 pull together my own program essentially
00:58 by merging these two fields weiu is an
01:02 ideal place to do this program because
01:05 it is one of the very top places in the
01:07 world in complex networks and systems
01:08 every day it feels like there's a talk
01:11 that I want to attend or it seems like
01:13 there's a class that I want to be taking
01:16 if you have a sense of what you want to
01:19 pursue but you can't you feel like it
01:21 kind of sits in between spaces that are
01:23 they exist the energy is really great
01:25 for that
