I am a Professor of Informatics and Computer Science at the Indiana University School of Informatics and Computing, and a member (and former director) of the Center for Complex Networks and Systems Research. I also have courtesy appointments in Cognitive Science and Physics, serve on the Scientific Leadership Team of the IU Network Science Institute (IUNI), and am a Senior Research Fellow of The Kinsey Institute and a Fellow at the ISI Foundation in Torino, Italy.
Research in my group, NaN, spans computational social science, network science, Web science, and data science, with a focus on analyzing and modeling the spread of information and misinformation in social media. We also study social computing, Web search and data mining, and science of science.
My calendar is a bit crowded. You may schedule an appointment with Tara Holbrook, our center’s administrative assistant. Or you can try your luck by Doodle MeetMe, email, phone (+1-812-856-1377), fax (+1-812-855-0600), or in person (Informatics East room 314).
Prospective students interested in joining my group, NaN, should look at this advice before contacting me. Then, if still interested, they should apply to one of our PhD programs: Informatics (Complex Systems track), Computer Science, Cognitive Science, or a combination. I am usually unable to respond to inquiries from prospective students unless they have already been admitted to one of these programs.

- ICWSM 2017 Workshop on Digital Misinformation
The deluge of online and offline misinformation is overloading the exchange of ideas upon which democracies depend. Many have argued that echo chambers are increasingly constricting the ability of alternative perspectives to provide a check on one’s viewpoints. Suffering fragmentation and declining public trust, the Fourth Estate struggles

- Why we study digital misinformation
If you get your news from social media, as most Americans do, you are exposed to a daily dose of hoaxes, rumors, conspiracy theories and misleading news. When it’s all mixed in with reliable information from honest sources, the truth can be very hard to discern.
- Cracking the stealth political influence of bots
Among the millions of real people tweeting about the presidential race, there are also a lot accounts operated by fake people, or “bots.” Politicians and regular users alike use these accounts to increase their follower bases and push messages. PBS NewsHour science correspondent Miles O’Brien reports on how CNetS computer scientists can analyze Twitter handles to determine whether or not they are
