I am a postdoctoral researcher at the University of Chicago, Department of Computer Science. I am a member of SUPERgroup and work with Prof. Blase Ur. I completed my Ph.D. in Computer Science on November 2017 at the Max Planck Institute for Software systems where I was advised by Prof. Krishna P. Gummadi.

I am broadly interested about incorporating human factors in security and privacy, and consequently designing usable online services. My recent research focus is on developing systems to provide usable privacy and security mechanisms to online users while minimizing system abuse.

Research Interests

I design, implement and analyze usable private and secure online systems. My work integrates security and privacy, human-computer interaction and systems research. My prominent ongoing research projects are as follows:

Improving usability of retrospective access management in online archives [PoPETS'19] [SOUPS'18]

We are investigating the effectiveness of tools which enable users to retrospectively modify (delete/edit old content or retrospectively change the audience) their past content in online archives (like social media or cloud storage). Our final goal is to design new mechanisms and systems which will let online users better manage the security and privacy of their old content.

Managing online data privacy and security via exposure [IJAESAM'17] [IC'17] [SOUPS'16] [USEC'14] [SOUPS'14] [CoNEXT'12] [EuroSys'12]

We developed the model of exposure control (controlling who actually views a piece of online content), an extension of existing access control (controlling who has access to the online content) for building more secure/private systems. We show that, in multiple real-world scenarios, exposure control enables us to better capture user intention and design more private and usable systems compare to the state of the art.

Limiting abuse (hatespeech) in online platforms [THAM'18] [HT'17] [ICWSM'16] [ICWSM'15]

We also investigated user behavior in online anonymous platforms. We identified that privacy and anonymity is a blessing to most of the user since they enable users to upheld free speech. However, a few users abuse the system under the veil of anonymity in the form of posting content like hatespeech. To that end, we work on developing techniques to detect and investigate hate speech in online platforms.

Systems developed

We created some online systems as part of our research to help social network users better understand and manage their data privacy.

  • Check Your Secondary Digital Footprint on Twitter: In Twitter, people may converse with you by mentioning your name in their tweets. These conversations constitute your secondary digital footprint. Secondary digital footprints are not created or controlled by you. However, they can still leak your personal information. Our Twitter application aims to help you check what information others leak about you on Twitter (You will need a Twitter account to use it ).

  • Friendlist Manager: Friendlists in Facebook are a great way to share your content with the people you intend to. But they are a huge pain to create and update. Our Facebook application was designed to facilitate and simplify management of your friendlists. Unfortunately the new version of Facebook API do not allow developers to fetch the data the app needed to use, consequently the app is not live any more. You can check the functions of this (now discontinued) app here.

  • Privacy IQ: Privacy IQ is a quiz that measures both your understanding of how privacy works on Facebook and your knowledge of your own privacy settings. However due to the change in Facebook API this app too is not live any more.
