With increase in usage of the Internet, there has been an exponential increase in the use of online social media on the Internet. Websites like Facebook, Instagram, Twitter, Tinder, YouTube, and many others have changed the way the Internet is being used. There is a dire need to investigate, measure, and understand online social media from various perspectives (computational, cultural, psychological). Real world scalable systems need to be built to detect and defend security and privacy issues on online social media. I will describe some cool projects that we work on: Distracted Driving, Elections, (Mis)Information / Fake content on Twitter, Facebook, and WhatsApp; Selfie deaths and KillFies; and Manipulated followers. Many of our research work is made available for public use through tools or online services at precog.iiitd.edu.in <precog.iiitd.edu.in/> including datasets precog.iiitd.edu.in/resources.html <precog.iiitd.edu.in/resources.html> that we have used in our research work. Our work derives techniques from Computational Social Science, Data Science, Statistics, and Network Science.
