I am a Ph.D. candidate at The University of Iowa studying issues related to security and privacy under the supervision of Zubair Shafiq. My research focuses on systematically investigating various types of abuses (e.g. spam, fraud, data misuse) on popular online social networks such as Facebook and Twitter. To this end, I perform longitudinal measurement studies to design data-driven countermeasures that can help online social networks in mitigating this abuse.
