I recently defended my PhD in the College of Computer &
Information Science at Northeastern University. My advisors are Alan Mislove and David Lazer.
In my research I am investigating the impacts of personalization in
various Web sevices. I am also interested in data mining and
measurements on online social networks and learning new tools for
analyzing large data sets.

I am currently a visiting researcher at the Computational Social Science group of GESIS in Cologne.
Fact-Cheking interventions on Online Social Networks
The prevalence of misinformation within social media and online communities can undermine public security and distract attention from important issues.
Fact-checking interventions, in which users cite fact-checking websites such as Snopes.com and Factcheck.org, are a strategy users can employ to refute
false claims made by their peers. We use data from Online Social Networks such as Twitter to find these conversations and to examine the contexts and consequences
of fact-checking interventions. Our preliminary results suggest that though fact-checking interventions are most commonly issued by strangers, they are more likely to draw
user attention and responses when they come from friends.
Measuring Price Discrimination on the Internet
In this project we are measuring the extent to which online purchasing sites vary the prices and the products they show to their customers.
There are many ways in which these websites are able to influence the final purchase of users, and many factors based on which they can personalize the pool
of products they offer. Our investigations include measurements on real users as well as simulations of browsing on some of the biggest e-commerce and travel sites.
