One of my lab’s major research areas is technology ethics – including related topics such as privacy and ethics education – and this is also a focus of my own public scholarship and outreach.


Research ethics for pervasive data. What can we learn from social media users about privacy and content norms that can inform best practices around research? What are the current practices of researchers? Focuses on Terms of Service violations, social media privacy, public perceptions, and controversy analysis (including the Facebook emotional contagion study).

Ethics and design for vulnerable populations. As researchers or designers, how should we take into account norms and special safety considerations for vulnerable communities online? Our first case study for this question is LGBTQ fandom communities. (Lead Researcher: PhD student Brianna Dym) [Funded in part by the NSF project PERVADE] [Publications: CSCW 2018 poster, TWC essay 2018, forthcoming TWC article 2020]

Ethics prep for tech companies. What are the most relevant ethical concerns for tech companies? This ongoing research focuses on controversy analysis, with future plans for working directly with start-ups. (Lead Researcher: PhD Student Natalie Garrett)

Ethics education. How can we best teach technology ethics? Integrated across curriculum? With speculative fiction? This research involves both classroom innovation and analysis of existing practices among those teaching tech ethics. (Collaboration with PhD student Natalie Garrett, former CU grad students Mike Skirpan and Nate Beard, and CS faculty Tom Yeh) [Publications: forthcoming SIGCSE paper 2020, SIGCSE 2018 (Third Best Paper Award)] [Press: Boing Boing 1, Boing Boing 2, The Conversation, The Daily Texan, The Nation, WIRED] [Public Scholarship: Tech Ethics Syllabi (Medium), CS Ethics Education (How We Get to Next), Black Mirror (How We Get to Next)]

Ethics through design fiction. How can we use creative speculation and negative design patterns to think through the ethical implications of technology? We are creating design fictions ourselves, as well as exploring how to support this practice for others. [Publications: GROUP 2018, TWC essay 2018] [Press: Boing Boing, WIRED] [Public Scholarship: Black Mirror (How We Get to Next)] [Workshop: CHI4Evil (CHI 2019)]


Public perceptions of tech ethics. Analysis of attitudes towards tech ethics and policy “in the wild” via public reactions to data sharing and privacy controversies in the media. (Collaboration with CU Comm student Blake Hallinan) [Publication: CHI 2018] [Press: local news (ABC7, ABC13, FOX31, and FOX8 in Denver), Refinery29, ] [Public scholarship: TOS (Slate), Facebook (Medium), Privacy & Digital Footprints (Medium)]

Data risk perception. How do experts and non-experts perceive risk around emerging, big data technologies? Recreation of a class risk perception survey in the next context of big data. (Lead Researcher: Former CU CS PhD student Mike Skirpan, in collaboration with CS faculty Tom Yeh) [Publications: CHI 2018]

Content & privacy on Facebook. Qualitative+quantitative analysis of Facebook content, discerning whether there are substantive differences in content based on privacy settings. Large corpus of Facebook status updates gathered from Mechanical Turk. (Conducted as a collaboration with other social computing PhD students and faculty at Georgia Tech.) [Publications: CSCW 2017]
