About

I am a first year PhD Student in the Technology and Social Behavior program at Northwestern University, which is a joint degree in Computer Science and Communications. I currently work with Darren Gergle, studying collaboration and coordination dynamics across different langugae speaking peer-production and collective action communities.

My research leverages both qualitative and quantitative methodologies in order to describe complex human behavior, interactions, relationships, and ovarching social mechanisms with both breadth and depth. I combine "big-data" and graph based analytical techniques, machine learning and natural language processing, and qualitative coding. I prefer to program in program in Python and UNIX.

Projects


Hyper-Lingual Collaboration

We use mixed method techniques to compare collaboration dynamics across different language communities, thereby expanding our understanding beyond the bounds of English speaking groups, surfacing mechanisms that result in content variation, and informing design solutions to better support global peer production. Our initial study uses a combination of network analysis and qualitative coding to explore Wikipedia talk and article pages from the top 25 largest language editions.

Rumoring During Crisis

This crisis informatics project explored rumoring behavior on social media during crisis situations. I used mixed “big-data” methods to analyze a ten million Tweet dataset from the Boston Marathon Bombings and to build toward machine learning based automatic detection. I published a paper to the 2015 ACM CSCW conference a short paper to the 2014 iConference, which won the “Best Note” award.

Mixed Language Identification

At Microsoft Research India I helped to build and refine a multilingual identification system that could classify bi-lingual Tweets across thirty Latin script languages in order to better understand textual code-mixing, and to ultimately inform the design of multilingual applications.
