I design experiments and software to study the ways in which humans and algorithms interact in digital spaces, especially as they pertain to information seeking. Currently, I am a postdoctoral fellow at the Stanford Internet Observatory. Before coming to Stanford, I completed my PhD in Network Science at Northeastern University, and was lucky to be advised by Christo Wilson, a computer scientist, and David Lazer, a political scientist. Prior to that, I worked with research psychologist Robert Epstein at the American Institute for Behavioral Research and Technology (AIBRT).
The research I've been involved with has been published in journals and conference proceedings including: PNAS, Proceedings of the ACM: Human-Computer Interaction, Proceedings of the International AAAI Conference on Weblogs and Social Media (ICWSM), Behavior Analysis: Research and Practice, and Proceedings of the Web Conference (WWW).
Although my publications to date have largely focused on political topics in web search, I am interested in applying my tools and methods to study online information seeking with respect to other topics, like race, gender, and health, and to study other online platforms, like social media. Feel free to drop me a line at ronalder[at]stanford.edu if you'd like to get in touch or talk about a project or idea.
