About me

I’m a PhD candidate in the Department of Sociology at Cornell University. I'm supervised by Mabel Berezin, Filiz Garip, and Michael Macy (chair). I’m a member of the Social Dynamics Lab. I use computational social science, primarily social network analysis, machine learning, and natural language processing, to study sociological questions, with a focus on political sociology and the sociology of culture.

For my dissertation I am studying the interactions between the supporters of social movements and political parties in the United Kingdom using millions of posts, likes, and comments from Facebook pages. I am also studying the relationships between different types of political organizations in the build up to the Brexit referendum and in its aftermath. I recently wrote a blog post about the role of social media 2017 UK General Election and co-authored an article in the Washington Post's The Monkey Cage blog on the recent German election.

A second line of research focuses on identifying and understanding hate speech and hate speakers on social media using natural language processing, machine learning and social network analysis. You can read our ICWSM paper on automated hate speech detection here and download our data and model here. Our work has been covered in Wired Magazine, Tech Republic, and New Scientist. We also wrote a paper focusing on the commonalities between hate speech detection and other topics, including online abuse and cyberbullying, for the Association for Computational Linguistics 1st Workshop of Abusive Language Online. You can read the article in the workshop proceedings.

I have also collaborated with Paromita Sanyal at FSU to study the impact of microcredit participation on women's social networks in rural India. We find that participation in associations allows women to expand their personal networks and enhance their social capital. Our work was recently published in Social Forces.

In the summer of 2016 I was an Eric and Wendy Schmidt Data Science for Social Good Fellow at the University of Chicago. I worked on a project using machine learning to improve an early-warning system to identify police misconduct and helped develop a new model to predict risks at the dispatch level. You can read about our work here, along with media coverage in The Chicago Tribune, NPR, Mother Jones, the Economist, and Forbes. As of spring 2017 our system is being implemented into two police departments, you can read about the progress here.
