I am a Ph.D. student in Computer Science at MIT CSAIL, advised by Prof. David Karger and a member of the Haystack Group and UID Group at MIT.

I work on designing and building systems to improve discourse, collaboration, and understanding on the web, with applications to social media, news, political discourse, education, and civic engagement. I also conduct research on computational analysis of large-scale social data to understand topics in the social sciences. My general interests are social computing, HCI, and computational social science.

Prior to MIT, I worked as a software engineer, completed a Masters in CS as a Gates Scholar at Cambridge, and a Bachelor in CS from Rutgers.

My research is supported by a Google Fellowship and NSF Graduate Research Fellowship.


coarse discourse

Characterizing Online Discussion Using Coarse Discourse Sequences

We present a novel method for classifying comments in online discussions into a set of coarse discourse acts towards the goal of better understanding discussions at scale. We collect and release a corpus of over 9,000 threads comprising over 100,000 comments manually annotated via paid crowdsourcing with discourse acts and randomly sampled from the site Reddit. Using our corpus, we demonstrate how the analysis of discourse acts can characterize different types of discussions, including discourse sequences such as Q&A pairs and chains of disagreement, as well as different communities. Finally, we conduct experiments to predict discourse acts using our corpus, finding that structured prediction models such as conditional random fields can achieve an F1 score of 75%.

Using Student Annotated Hashtags and Emojis to Collect Nuanced Affective States

Determining affective states such as confusion from students' participation in online discussion forums can be useful for instructors of a large classroom. In this work, we harness affordances prevalent in social media to allow students to self-annotate their discussion posts with a set of hashtags and emojis, a process that is fast and cheap. From a dataset of over 25,000 discussion posts from two courses containing self-annotated posts by students, we demonstrate how we can identify linguistic differences between posts expressing confusion versus curiosity, achieving 83% accuracy at distinguishing between the two affective states.

Wikum: Bridging Discussion Forums and Wikis using Recursive Summarization

Large-scale discussions between many participants abound on the internet today, on topics ranging from political arguments to group coordination. But as these discussions grow to tens of thousands of posts, they become ever more difficult for a reader to digest. In this article, we describe a workflow called recursive summarization, implemented in our Wikum prototype, that enables a large population of readers or editors to work in small doses to refine out the main points of the discussion. More than just a single summary, our workflow produces a summary tree that enables a reader to explore distinct subtopics at multiple levels of detail based on their interests.

Mavo: Creating Interactive Data-Driven Web Applications by Authoring HTML

Many people can author static web pages with HTML and CSS but find it hard or impossible to program persistent, interactive web applications. We show that for a broad class of CRUD (Create, Read, Update, Delete) applications, this gap can be bridged. Mavo extends the declarative syntax of HTML to describe Web applications that manage, store and transform data. Using Mavo, authors with basic HTML knowledge define complex data schemas implicitly as they design their HTML layout. They need only add a few attributes and expressions to their HTML elements to transform their static design into a persistent, data-driven web application whose data can be edited by direct manipulation of the content in the browser.

Exploring Social Browsing

While the web contains many social websites, people are generally left in the dark about the activities of other people traversing the web as a whole. We explore the potential benefits and privacy considerations around generating a real-time, publicly accessible stream of web activity where users can publish chosen parts of their web browsing data. We also develop a new social media system for collecting, sharing, and visualizing aspects of one's browsing history.

Gender and Ideology in the Spread of Anti-Abortion Policy

In the past few years an unprecedented wave of anti-abortion policies were introduced and enacted in state governments in the U.S., affecting millions of constituents. We study this rapid spread of policy change as a function of the underlying ideology of constituents. We examine over 200,000 public messages posted on Twitter surrounding abortion in the year 2013, a year that saw 82 new anti-abortion policies enacted. From these posts, we characterize people's expressions of opinion on abortion and show how these expressions align with policy change on these issues.

Conference Recommendation and Meetups

Confer is a tool for conference schedule organization and session/paper recommendation. Using the interface and the data, we are exploring ways to facilitate meetings, particularly between new and established members of research communities using this tool. We piloted a meetup session at CSCW '15 called "Confer Coffee", creating groups from people who liked similar papers on Confer, who then gathered in person at the conference, and we are interested in piloting more sessions in future conferences that use Confer.

mailing lists

Reimagining the Mailing List

Mailing lists have existed since the early days of email and are still widely used today, even as more sophisticated online forums and social media websites proliferate. We explore why members prefer mailing lists to other group communication tools. But we also identify several tensions around mailing list usage that appear to contribute to dissatisfaction with them.

Modeling Ideology and Predicting Policy with Social Media

We study the many voices discussing an issue within a constituency and how they reflect ideology and may signal the outcome of important policy decisions. Focusing on the issue of same-sex marriage legalization, we examine almost 2 million public Twitter posts related to same-sex marriage in the U.S. states over the course of 4 years starting from 2011.

Visualizing Text Corpora to Compare Media Frames

We develop a visualization technique and visual analytic system that enables the study of media frames across text corpora. In particular our system allows scholars or other analysts to compare media frames in a visualization called the Compare Cloud, which explicitly maps word prevalence and context information between two corpora.

Spreadsheet-backed Web Apps

We present a system for creating basic web applications using such spreadsheets in place of a server and using HTML to describe the client UI. Authors connect the two by placing spreadsheet references inside HTML attributes. Data computation is provided by spreadsheet formulas. The result is a reactive read-write-compute web page without a single line of Javascript code.

Kinetic Scrolling on Mobile and Tablets

To support navigation of long documents on touchscreen devices, we introduce content-aware kinetic scrolling, a novel scrolling technique that dynamically applies pseudo-haptic feedback in the form of friction around points of high interest within the page. This allows users to quickly find interesting content while exploring without further cluttering the limited visual space.

Moral Framing in Climate Change Blog Discourse

In this work we develop a novel operationalization of moral evaluation frames and study their use within a corpus of blogs discussing climate change. We develop a text visualization tool called Lingoscope that allows the user to observe and filter the contextual terms that convey moral framing across large volumes of text, as well as to drill down to specific examples.

Controversy and Sentiment in Online News

In this work, we take a data-driven approach to understand how controversy interplays with emotional expression and biased language in the news. We begin by introducing a new dataset of controversial and noncontroversial terms collected using crowdsourcing. Then, focusing on 15 major U.S. news outlets, we compare millions of articles discussing controversial and non-controversial issues over a span of 7 months.

Visual Analytics of Media Frames

There is interest in trying to identify new frames around issues, and to compare how types of frames vary across different news outlets, or over time. We consider these analytic needs in the context of two use-cases relating to news producers and news consumers, and describe the initial design of a visual analytics tool, the LingoScope, in terms of how it supports these use-cases.

Diurnal Urban Routines on Twitter

We study and characterize diurnal patterns in social media data for different urban areas, with the goal of providing context and framing for reasoning about such patterns at different scales. Using one of the largest datasets to date of Twitter content associated with different locations, we examine within-day variability and across-day variability of diurnal keyword patterns for different locations.
