Hi! I'm Ruogu. I am a 5th year PhD student at Human-Computer Interaction Institute, Carnegie Mellon University. My advisor is Prof. Sara Kiesler .
My research is about understanding how people share information and supporting better information sharing. More information transparency could facilitate collaboration and innovation. However, people do not always know what is the right information to share with others and may not be willing to share some information because of privacy and security concerns. My research about Internet anonymity and information sharing in collaborative work starts to investigate these problems.
Before entering CMU, I got my Master's degree in Human Factors from University of Illinois at Urbana-Champaign. I worked with Prof. Wai-Tat Fu there on information search and social tagging.
I was born in Xi'an, Shaanxi, China. I came to United States in 2008. Before that I did my undergraduate study at Tsinghua University, and worked at the Institute of Human Factors and Ergonomics.
In my spare time, I enjoy watching movie, travelling, and swimming.

My current research focuses on these two directions:
Internet anonymity and information transparency
2010 - now | with Sara Kiesler, Stephanie Brown, and Laura Dabbish | CMU
This project investigates people's experience with anonymity on the Internet and their attitudes about managing personal information online. It was developed under the XIA project about the next generation of the Internet. I conducted interviews with people from seven different countries to find out why they want to be anonymous and what method they use to achieve anonymity online. I also designed and analyzed an international survey and a U.S. representative survey (collaborated with Pew Research Center) on how people manage their online information and their opinions on anonymity and privacy.

Paper 3: Social transparency in networked information exchange [paper]
Information and knowledge sharing in asynchronous collaborative analysis
2010 - 2014 | with Sara Kiesler, Aimée Kane, and Susan Fussell | CMU
This project is about supporting implicit information sharing in asynchronous collaborative work. The goal of this study is to make analysts' work more transparent so that it could help another person perform better on the same task.
Study 2: The influence of sensemaking tools and partners' information quality on collaborative analysis [paper]
Study 1: The use of annotations in asynchronous collabortion [paper][poster]
In the past, I have worked on several other projects.
Crowdsourced Learning on the Job: A Case Study in Collaborative Translation
Fall 2010 | with Jeff Rzeszotarski, Kerry Chang, Peter Kinnaird, and Niki Kittur | CMU
We investigated translation tasks on Amazon's Mechanical Turk crowdsourcing market. By examining workers translating both individually and in groups, we provided a use case for interface development that supports collaborative translation and we showed that crowdsourcing can gainfully employ workers in developing regions while at the same time allowing workers to learn language skills.
Information searching and domain expertise
2008 - 2010 | with Wai-Tat Fu, Jibo He, and Thomas G. Kannampallil | UIUC
This study compared how domain experts and novices performed exploratory search using a traditional search engine and a social tagging system. Results showed that social tagging systems could facilitate exploratory search for both experts and novices. We found a dynamic interaction between knowledge-in-the-head and knowledge-in-the-social-web that although information seekers are more and more reliant on information from the social Web, domain expertise is still important in guiding them to find and evaluate the information.

Understanding factors affecting perceived sociability of social software
2006 - 2008 | with Qin Gao, Yusen Dai, Zao Fan, and Yuancheng Yang | Tsinghua University
The goal of this study was to identify factors that affect Chinese users' perception of the sociability of social software. We conducted interviews and questionnaires to understand how people use different social software to supplement their social life and to explore the possible factors that influence the users' utilization of social software. Results show that sociability is influenced by social climate, benefits and purposes, people, interaction richness, self-presentation, and support for formal interaction.
