The Community Data Science Collective (CDSC) is an interdisciplinary research group made up of faculty and students at the University of Washington Department of Communication, the Northwestern University Department of Communication Studies, the Carleton College Computer Science Department, the School of Information at UT Austin and the Purdue University School of Communication.
We are social scientists applying a range of quantitative and qualitative methods to the study of online communities. We seek to understand both how and why some attempts at collaborative production — like Wikipedia and Linux — build large volunteer communities and high quality work products.
Our research is particularly focused on how the design of communication and information technologies shape fundamental social outcomes with broad theoretical and practical implications — like an individual’s decision to join a community, contribute to a public good, or a group’s ability to make decisions democratically.
Our research is deeply interdisciplinary, most frequently consists of “big data” quantitative analyses, and lies at the intersection of communication, sociology, and human-computer interaction.
To learn more about the CDSC, please check out our about page (especially the links there). Prospective students should also review these materials.
Courses
In addition to research, we teach classes and run workshops. Some of that work is coordinated on this wiki. A more detailed lists of workshops and teaching material on this wiki is on our Workshops and Classes page. In this page, we only list ongoing classes and workshops.

Public Data Science Workshops
Community Data Science Workshops — The Community Data Science Workshops (CDSW) are a series of workshops designed to introduce some of the basic tools of programming and analysis of data from online communities to absolute beginners. The CDSW have been held six times in Seattle between 2014 and 2020. So far, more than 100 people have volunteered their weekends to teach more than 500 people to program in Python, to build datasets from Web APIs, and to ask and answer questions using these data.

Research Resources
If you are a member of the collective, perhaps you're looking for CommunityData:Resources which includes details on email, TeX templates, documentation on our computing resources, etc.
About This Wiki
This is open to the public and hackable by all but mostly contains information that will be useful to collective members, their collaborators, people enrolled in their projects, or people interested in building off of their work. If you're interested in making a change or creating content here, generally feel empowered to Be Bold. If things don't fit, somebody who watches this wiki will be in touch.
This is mostly a normal MediaWiki although there are a few things to know:
- There's a CAPTCHA enabled. If you create an account and then contact any collective member with the username (on or off wiki), they can turn the CAPTCHA off for you.
- Extension:Math is installed so you can write math here. Basically you just add math by putting TeX inside <math> tags like this: <math>\frac{\sigma}{\sqrt{n}}</math> and it will write .

- Community Dialogue Wrap Up: Zarine Kharazian and Paul Gowder Discussed the Role of Community Governance
- We held our 11th Science of Community Dialogue on April 4th, with Zarine Kharazian (University of Washington) and Professor Paul Gowder (Northwestern University) sharing their research on misinformation and propaganda in online communities, limitations of approaches that neglect community governance, and insights on democratizing platforms and society. Zarine kicked off the conversation by highlighting recent …

- Half-Baked, Full-Throttled
- We all wear a lot of hats as researchers. Cowboy hats as we lasso and wrangle data. Noir-style fedoras when we are pinning post-it’s to a wall and stringing together our evidence. Berets when we ponder over the perfect artistic metaphor to describe our results. Sitting dusty in the corner is the tocque, the baker’s …

- Online Communities as a Support System
- As I’m sure many before me can relate to… after a class here, a conversation with someone there, and a hop, skip, and a jump later, somehow I tumbled my way into grad school! When I began graduate school, I knew I was interested in the intersection of health communication and online communities, but beyond …
