The SPARTA Lab is currently looking for self-motivated students seeking a Ph.D. in Computer Science and interested in pursuing research in topics related to computational social science, online privacy, and Internet measurement. Send an email to "rishab[-]-nithyanand[at]uiowa[dot]edu" with the subject "you NEED to hire me!" if you're interested in working with us and have a demonstrably strong background in any of the following areas: computer networking, statistics, text analytics, or experiment design.
Our focus is on identifying avenues and understanding the mechanics of online radicalization. Our end-goal is to use this understanding to develop better (more effective and scalable) interventions for vulnerable individuals on the cusp of radicalization.
We are currently working on several projects to (1) identify how radical ideologies flow between online communities and from online to offline communities, (2) measure the impact of algorithmic bias in search and recommendation systems on the ideologies of vulnerable individuals, and (3) understand how the misuse of new technologies (e.g., push notifications) can unintentionally result in populations more vulnerable to radicalization.
