I am a Postdoctoral Scholar in the Department of Communication Studies at Northwestern University, a member of the Community Data Science Collective, and have just completed my PhD in the Department of Communication at the University of Washington. My scholarship studies collective action online and primarily focuses on "peer production." This form of organizing has most famously produced public information goods like Wikipedia and open source technologies and also plays an important role in social movements. I use methods of computational social science to understand what limits online organizing and how to expand its potential.
Many people invoke “ecosystem” as metaphor to emphasize complexity and interdependence in communication systems like the Internet. However, there is also a huge natural science called “ecology” which successfully learns about biological ecosystems. Organizational sociologists and communication scientists have already appropriated theories, models and methods from ecology to understand interdependence between human organizations like firms and social movements. I draw both from these social science literatures and from bio-ecology to understand how environmental contexts and interdependence between online communities shapes their growth, survival and organizing processes.
In my ICWSM 2022 paper with Benjamin Mako Hill, I use time series analysis to infer when overlapping online communities hosted on Reddit are competitors or mutualists and find that mutualism is much more common than competition. To help explain why overlapping communities are often mutualists, my collaborators and I interviewed members of these overlapping online communities. As described in our CSCW 2022 paper, people seek different types of benefits from online communities such as a like-minded community, specific information and an audience for their content. Tensions between the different benefits mean that "no community can do everything," but one can obtain a greater range of benefits from a portfolio of overlapping communities.
My research also investigates quality control and machine learning systems in peer production. My paper published in CHI 2017 with Aaron Shaw and Benjamin Mako Hill shows that quality control systems often become increasingly hostile to newcomers and difficult to change over time. These mechanisms, which limit Wikipedia's growth and diversity, are common in a range of digitally mediated forms of organizing. Online organizations increasingly use data science methods as a part of their quality control systems. In my CSCW 2021 paper with Benjamin Mako Hill and Aaron Halfaker, I used a regression discontinuity analysis to evaluate how algorithms for flagging encyclopedia edits shape the fairness of Wikipedia moderation. I also introduce an improved machine learning method for measuring Wikipedia article quality in my OpenSym 2021 paper .
My academic work has received generous support from the National Science Foundation through the Graduate Research Fellowship Program (GRFP) and through the cyber-human systems program.
In the past, I worked at Microsoft where I developed search suggestions for Bing multimedia and as a technician at the Pacific Northwest National Laboratory (PNNL) where I measured foaming molten glass as part of a project to store nuclear waste. I went to college at Whitworth University where I received a double-B.S. in Mathematics and Computer Science in 2012.

Online communities are central parts of each of our daily lives and have an important impact on our cultural, social, and economic experience of the world and each other. This course combines an in-depth look into several decades of research into online communities and computer-mediated communication with exercises that aim to give students experience applying this research to the evaluation of, and hands-on participation in, online communities.
