Meet the FCL Team

Clio Andris
Lab Director

        I am an assistant professor in the schools of City Planning and Interactive Computering at Georgia Tech. I teach GIScience classes at multiple levels. At Penn State, I am involved in a diverse set initiatives. I am on the Graduate Faculty of the Social Data Analytics (SoDA) Program, Associate Faculty of the Institute for CyberScience, Affiliate of the Population Research Institute (PRI) and Faculty Member of the Operations Research Program. I was a postdoc at Los Alamos National Laboratory (2014), Santa Fe Institute (2012-2014), MIT Dept. of Urban Studies and Planning (2012), and Singapore-MIT Alliance for Research and Technology (SMART) (2011-2012). I have a Ph.D. in Urban Information Systems (MIT, 2011), MS in Geography (U. South Carolina, 2008) and a BA in American Studies with Geography minor (Boston U., 2006). I was a National Defense Science and Engineering Graduate (NDSEG) Fellow during my Ph.D. and was a member of the Senseable City Lab under Carlo Ratti. I have been advised by Luis Bettencourt (SFI), Joseph Ferreira Jr. (MIT) and David Cowen (USC). I’m originally from Washington, DC, and I live in Boalsburg, PA in a very old house with a bunny.

Sambhavi Joshi
Graduate Research Assistant

        I am a Masters in Geographic Information Science and Technology candidate at Georgia Institute of Technology. My research interests are on the threads of analysing Socio-Economic Attributes using GIS. I am also interested in studying use of geographic data to understand interaction between physical spaces and human activities.
        I have a Bachelor’s Degree in Urban Planning from Maulana Azad National Institute of Technology, India (2018). Before joining Georgia Tech, I worked at Indian Institute for Human Settlement as a Geospatial Intern, analysis housing situation of lower income group in the city of Delhi.

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.

Matthew Lim
Undergraduate Assistant

        I am a bachelor’s student in Computer Engineering at Georgia Tech pursuing a minor in Sustainable Cities. I have interests in Human-Computer Interaction and educational maker spaces. I’m also interested in Computer Architecture, UX design, and software development. I’m currently on the executive board of Georgia Tech’s ECE Makerspace and have worked at companies like Siemens, Autodesk, and Georgia Tech Research Institute. I hope to continue my education at Georgia Tech in either a Masters in ECE or Human-Computer Interaction.

Josh Baker
Undergraduate Researcher

        My name is Josh Baker. I am a graduating Computer Science major at Georgia Tech, focusing on Modeling/Simulation and CS Theory. My particular fields of interest are in the intersection of computing and mathematics, specifically in Optimization and Algorithms.

        I heard about the Friendly Cities Lab last year, and was immediately interested in the work they were doing. The intersection space of interpersonal relationships with geospatial networks is a new one to me, but I have been thoroughly enjoying the opportunity to learn more about it.

        I am soon to begin working for Innovative Defense Tech as a software engineer. My previous work experience has been at Sandia National Labs as an undergraduate research associate. Some projects I have worked on include work in container systems, scientific workflow systems, and simulation studies.My primary goals at this point are to develop my computing skills in industry work, while preparing to enter a graduate program for Mathematics with the eventual aim of a PhD in Math.Some of my other interests include STEM outreach and education, Machine Learning, and collegiate fencing.
