A PhD student in the Department of Information Science at Cornell University. My major concentration is Human-Computer-Interaction, and minor is Communication.
I am currently working with Prof. Dan Cosley and Prof. Susan R. Fussell in Information Science Department, and also Prof. Natalie Bazarova in Communication Department. They are also my committee members. My research mainly focus on Human-Computer-Interaction, Social Aspect of Information and Social Psychology of Communication.
Having been trained as a system developer and UX designer prior to coming to Cornell, now I see myself as who combines design, system and theory together to seek advances to improve people’s connection and communication.
Here is my
My research interests are mainly Human-Computer-Interaction, Computer-Supported-Collaborative-Work and Social Media. I have led several projects including stranger-orientated social networking, event-based social networks, social ephemerality, machine-translation-aided communication and visualization-supported communication.Research Projects
As a master student, I was trained as a developer and designer concentrates on social mobile systems. I designed and developed social systems for Tsinghua University, academic conferences and Nokia China. I also led a student group in a joint project of Tsinghua University and Nokia Research Center.Research Projects
My undergraduate major concentration is information and signal processing. I worked with Pro. Gang Xu on facial recognition, which won University's undergraduate honorable thesis of year 2008.
I worked as a research intern at IBM Watson Cognitive Computing Group. My research here focuses on designing cognitive tools that supports remote collaboration.
I worked as PhD research intern at IBM Watson USER group. My research here focuses on designing tools for personality presentation on social media.
I worked for almost two years as UX research intern in the team of Mobile Social Experience team, where we seek innovations on mobile social technologies and researchers. It was a great experience to work closely with researchers, developers and designers together on various projects for such a long time. During that time, my work was mainly focused on data analysis and system design and development, and here are some works I did:
For about a semester, I worked in the Visual Information Processing Lab led by Pro. Liao Qingmin on Image processing systems. My work is mainly on researches on Pattern Recognition. I was involved in the algorithm development in a Vehicle Platte Recognition project.
As a Software Engineering Intern, I worked in Mobile Social System team led by Dr. Hao Wang. By working with experience Backend and Front-end developers, I was trained as a mobile system developer. Back to 2009, before Android OS and iOS dominating mobile OS, with the vision of Nokia as a leader in mobile business, we were the early explorers of mobile technologies in social contexts. I worked with other developers and built a conference and office meeting system using Wi-Fi-based indoor positioning technology to support meeting people offline and social networking online.Projects
I am developing this concept called "Ephemeral Sociality" based on a fact that even though we form persistent relationships with others, the social interactions between are still transient and ephemeral. In another word, the network consists of fleeting and transient, yet iterative social relations; of ephemeral but intense interaction. Being ephemeral means the achieve-like posting and sharing behaviors in most social system would raise questions when people would like to share not persistent interactions. For example, we see Snapchat as a system that regulates a norm of ephemerality that other system does not. The goal of developing this topic is to probe the temporal domain of social interactions and self-disclosure in social systems and let the designers rethink the persistency and ephemerality of digital systems. One former related work is "Ephemeral Social Network" where we looked at the importance of ephemeral physical co-location and encounters in networking, but we did not explore the system-level ephemerality. More reading of my work on digital ephermality can be found here at my Medium
I work with Tina Chien-Wen Yuan, Pro. Dan Cosley and Pro. Susan R. Fussell on this topic. We want to investigate how to use social media data to facilitate people's connection and communication, especially in cross-cultural domain. [Slides in CSCW2014]
I work with Pro. Dan Cosley on this project. We are interested in how events in people's real life promote, maintain and change social networks , as well as how social networks in these events influence the creation, diversity, participation and also reminiscence of events.Studying this relationship is crucial to better understanding the factors influencing social network development and its expression in both the physical and digital worlds, and to provide implementation guidelines in the design of social networking applications, recommendation systems and social organizations.

I work with Dongwook Yoon and Huaishu Pengon this project. We aim to understand the share-ability of contents for ebook systems with two different sharing mechanism - the page-based one and the content-based one for the appropriate reference fashion for e-books. We expect this study will render design implications for future electronic documents in general. [Poster in CHI2013]
Social networks between people are not simply social graphs where nodes are connected by links, there are sharing objects between people, like parties, events, places in physical world, or pages, photos, groups in online world. Social objects are either binding, or bridging people together. In a word,it is through social objects that people connect to each other, not only the links between them. Inspired by Jyri Engeström’s article on “Object-centered sociality”, I want to look at different social objects: what are the existing social objects in a social system that mediate the interaction inside the system and in physical life, how the objects work, how to improve their sociality by design, and what new beneficial objects could be. An example of this topic is the "Event-based Social Network" project where we found smaller events as a shared object between event participants, would promote more social connections rather than large events. I would like to investigate more social objects like photos on Pinterest, sharing on Facebook, etc. The goal of investigating social objects is not only understand the sociality, but re-think the graph-like anatomy of current social network, to approach new model to capture the interactive aspects in social networking life.
I work with Ge Gao , Pro. Susan R. Fussell and Pro. Dan Cosley on this topic. We are aiming to better understand and support communication between people who speak different native languages by enhancing MT output with other information, such as keyword highlighting, accuracy info, etc.   
I used a mobile location-based system and conducted several filed trials to collect a certain scale of users' location data and social links information. Then data are employed to analysis the attributions of the multi-mood networks built by users, including analyses in user behavior patterns under different application scenarios, the mining of correlation between networks regarding to their formations and evolutions, the study of relationship between user behavior and network developing, and then the explorations of correlation model between users' attributions and their actives.

I worked with Dr. Zhen Liu, Dr. Xia Wang and Dr. Alvin Chin on the concept of Ephemeral Social Network (instantaneous social networking)to provide users with a truly mobile social networking experience, and discuss some research issues and challenges.
