We are a research group within the School of City & Regional Planning and School of Interactive Computing at Georgia Tech. We are working on a new field of study: interpersonal relationships and social networks in geographic space. Keywords: geographic information systems (GIS), social networks, urban planning, urban analytics, information visualization, complex systems.


Research Themes

SPATIAL SOCIAL NETWORK (SSN) ANALYSIS
We analyze traditional social networks from sociology within a GIS environment. We develop metrics to show how relationships are hindered or helped by the built environment, and how powerful individuals benefit from the surrounding environment. (see Foundational Paper, Syrian Refugee Project, Facebook Project, and Mafia Project)

REGIONAL NETWORK ANALYSIS 
How connected are places? We measure how connected places are and how this reflects the culture, diversity, and idea flow of a city. We find hidden connections by developing a new measure of social distance: the strength of social flows between places. Social distance is driven by connecting over political/administrative, natural, and infrastructural boundaries, and through institutions (universities, military bases, governments), social ties, and shared culture. (see Foundational Paper, Big Brothers Big Sisters Project, and NCAA Athletes Project)

APPLIED PLANNING FOR RELATIONSHIPS IN THE CITY
We help urban planners plan better cities by finding the amenities (parks, bars, Tinder, kayaking?) that best support personal relationships such as friends, families, co-workers, organization-based relationships, and romantic relationships). (see Yelp Project and Romance in-State College Paper)

GEOVISUALIZATION + INFORMATION VISUALIZATION
We create interactive visualizations and tools for exploratory spatial data analysis (ESDA) with HCI principles in mind. (see Data and Interactive Page)


Working with us

Thanks for your interest in working with our group. If you are applying to Tech for a graduate degree, we have a great team who makes admissions decisions for our PhD, MCRP, MGIS, MSUA, etc. programs. However, our lab is NOT involved in this process and we don’t make the decisions. Instead of emailing, please write that you are interested in working with the lab and/or with Clio in your personal statement.

Email clio@gatech.edu if you fall under these categories:
If you are a college student volunteer, you can join the lab on a project for class credit. You are expected to attend weekly meetings.

If you are a high school student volunteer, you should come with a clear sense of what you may want to do, include it in your email. (Find a cool data set you want to analyze or something you are passionate about). At this time, we do not have “helping hands” kinds of tasks for those who haven’t taken a GIS class. (Sorry about that.)

If you are a funded postdoctoral scholar or visiting faculty member, we do have opportunities for visitors. If there is a project or co-teaching experience we can agree on, it is possible to arrange a visit (but I will need to seek approval for this). We do not have funding for postdocs or unpaid sabbaticals right now.

Also, please refrain from sending personal pictures, info on date of birth, marital status, and religion, and please do not put this information on your CV. 🙂 Thank you.
