Seolha Lee – Graduate Research Assistant

I’m a graduate student in the Master of City and Regional Planning program at Georgia Institute of Technology. My research interest lies in visualizing overlooked human activities and interactions in a built environment through data technology. Also, I’m interested in studying the relationship between online activities (social media, e-commerce, etc.) and spatial behaviors in pursuit of human-centered urban planning and design. Before joining the Friendly Cities Lab, I worked as a research assistant in Maturepolis Lab at KAIST in South Korea and City Regional Studies Center at the University of Alberta, Canada. I also worked as a researcher in YANGJI.CO., an urban planning and design consulting firm in Seoul. I hold a BA in Civil & Environmental Engineering with a Geography minor at Seoul National University. Currently moved to Atlanta from Seoul, I’m continuing my exploration in cities with different fabric filled with intriguing dynamics.

Shaarif Sajid – Graduate Researcher

I am a first-year Ph.D. student in the College of Computing at Georgia Tech.



Xiaofan Liang – Graduate Research Assistant

I am a Ph.D. student in the School of City and Regional Planning, advised by Dr. Clio Andris. My research interests revolve around understanding how human movements (e.g., trajectories) and activities (e.g., consumption) at a micro-scale give rise to the spatial and network structures that further characterize cities on a macro-scale (segregation, street scenes, industrial structure, etc.). My ongoing projects include measuring the urban environments conducive to chain restaurants and analyzing a multiplex network of mobility, investment, knowledge, and social media friendship flows in China. Occasionally, I consult new businesses with a mix of commercial and social (or cultural) goals to better understand the meanings and impacts of their moves on cities as the Data Lead at MaxLab. In the future, I hope to contribute to building more socially sustainable cities in Asia.
I received a Bachelor’s Degree in Sociology from UC-Berkeley (2015). I pursued another Bachelor’s Degree in Computer Science from Minerva Schools at KGI (2019), through which I rotated to study in six different countries over four years and grew my interests in cities! Before coming to Georgia Tech, I was an REU at Santa Fe Institute (2017 and 2018), from where I fell in love with complexity science and Clio’s work.
