I am a 5th year PhD Candidate in the Department of Politics at NYU and a member of the Social Media and Political Participation (SMaPP) lab. In fall of 2018, I will join the Princeton Center for the Study of Democratic Politics as a postdoc, before beginning as an Assistant Professor in the Department of Political Science at Penn State University in the fall of 2019. My dissertation studies the political implications of new forms of communication enabled by the internet and social media. This work involves developing innovative methods for performing online behavioral experiments and creating new ways to use text as data.
An urgent example of these changes is the explosion of uncivil discourse online. In contrast to deliberative communication, which is essential to a functional democracy, uncivil political discourse polarizes participants and inhibits learning. My Job Market Paper (invited to revise and resubmit, American Political Science Review) describes an experiment I conducted during the 2016 US Presidential election designed to decrease high-profile poltical incivility. I find that various kinds of moral suasion can cause people to be less incivil, but that these interventions tend to be more effective on subjects who are more inveseted in their online identities. This work builds on methods I developed to combat the online harassment of African Americans. In "Tweetment Effects on the Tweeted" (published in Political Behavior), I used bots (fictitious personae with social media accounts I create and control) to sanction Twitter users engaged in racist harassment. I found that sanctioning can have a substantial, durable effect in reducing racist harassment--but that this sanctioning is most effective when the sanctioner and subject share a relevent social identity. These online behavioral experiments represent an important innovation, allowing researchers to conduct controlled experiments on difficult-to-reach populations at scale and with high levels of ecological validity. I recently conducted (with Jorge Gallego, Juan D. Martinez and Mateo Vasquez) a similar experiment aimed at informing politically interested citizens during the 2016 Colombian Peace Plebiscite.
Modern media technology has also enabled more targeted and personalistic elite political communication. Using an innovative design that matches panel surveys with objective measures of respondents' social media diets, I find (with Patrick Egan, Jonathan Nagler, Jonathan Ronen and Joshua Tucker) that information from traditional media sources does in fact increase factual political knowledge while information from parties increases knowledge of those parties' platforms (invited to revise and resubmit, American Political Science Review). Elite communication on social media takes a slightly different form in non-democratic contexts; in research with the SMaPP lab (published in Political Science Research & Methods), I find that the Venezuelan regime strategically distracted their followers from large-scale protests.
Much of my research has entailed methodological innovation, especially in the use of Text as Data to analyze trends in political communication. In more explicitly methodological work (with Arthur Spirling and Ken Benoit), I have developed an improved measure of textual complexity using crowdsourcing and machine learning to discover the textual features that best capture empirical textual complexity. In a forthcoming book chapter, we demonstrate that the State of the Union address has declined in complexity relative to other corpora of political text.
My research agenda and teaching have been strongly complementary. In addition to one semester of undergraduate Intro to American Politics, I have served as a teaching assistant for four semesters at NYU's Center for Data Science: one semester of (Master's-level) Text as Data, and three semesters of (Master's-level) Intro to Data Science. NYU was the first school in the world to offer a MS in Data Science, and for the past two years, I've been responsible for teaching incoming classes the basics of Data Science using Python.
