Xi liu - Graduate Associate
I am a PhD candidate in the Department of Geography at Penn State. I have broad research interests in urban computing, social networks, and complexity. Before working at the Friendly Cities Lab, I was a member of the Geosoft Lab at Peking University, where I received a master’s degree in GIS. My bachelor’s degree is also in GIS from Tongji Univeristy, with a minor of economics from Fudan University. My niche, methodologically, is a combination of data-driven techniques (e.g. network analysis, data mining) and geographical theories. My previous work focused on using ‘big’ geo-data to enhance our understanding of human mobility and urban structure. The topics I am currently working on including urban complexity, social flows, spatially embedded social networks, etc. I am trying to bring in more social perspectives into my research.
sohrab rahimi - Graduate Associate
I am currently enrolled in the PhD of Architecture with a minor in Applied Statistics as well as the Master of GIS program at Penn State. I have been working with Friendly Cities Lab since 2015. My primary research interest pertains to interactions between humans and the environment from a socio-spatial point of view. Currently, my research focuses on using non-traditional data sources that inform us about the cultural and societal characteristics of neighborhoods and cities. So far I have been involved in a number of projects in this lab including: the environmental indicators of social capital, the spatial determinants of romantic relationships and the analysis of interior spaces of Airbnb units in 10 major cities, and the effects of geographical space on candy tastein the USA.
Dr. Li-San Hung - Post-Doctoral Researcher
I recently received my Ph.D. from the Department of Geography at Penn State (minor in Demography), and joined FCL as a post-doctoral research associate in August, 2016. I am a human/environment geographer with the research interests in human dimensions of natural hazards and human behavior in the natural environment. My dissertation research used a dyadic approach to understand household hurricane preparedness, and this study spurred my interest in understanding how interpersonal relations influence human/environment relations.
Sara cavallo - Graduate Assistant
I am a PhD Candidate in the Department of Geography at Penn State. I have MS in Geography from Penn State and a BA in Geography & Economics from Colgate University. My research Interests are political ecology, agri-food studies, geographies of health, and mixed methods. What draws me to geography is its inherent interdisciplinarity and how it allows us to examine nature-society relationships through multiple perspectives and approaches. Broadly, I’m interested in understanding the links between ecological health and human health, particularly through the lens of nutrition. For my dissertation work, I am looking at plant disease in western Uganda and its relationship to food practices and nutritional attainment. My previous work has revolved around the tea industry in Uganda and its connections to conservation and development via agroforestry policy and practice.
Margret Logan - undergraduate Researcher
I have always appreciated technology, learning new tools, and creating things. At Penn State, I am working towards my goals as a designer by mastering new technical skills, and exercising my brain creatively. I am currently a Junior majoring in Industrial Engineering.

Mengchen wang - undergraduate Researcher
I am a senior in Petroleum and Natural Gas Engineering at Penn State. I joined the team to work on topics in geography and to broaden my horizon. My job is dealing with big data sets through programming and data analysis. I have learned a great amount so far. Though my work at FCL is outside of my major, I will extend the knowledge I gained here into my major and I will look at problems from another angle. It is a pleasure to work in the Friend City Lab.
I am currently a Ph.D. student in the Department of Statistics and a first year BDSS-IGERT trainee. I have a wide variety of interests that bridge the gap between statistics and the social sciences, including spatial statistics, human interactions, data mining, and data privacy. Currently, my research centers on the movements of undergraduate students that have studied at Penn State. A lifelong Penn Stater, I completed my undergraduate degrees in Statistics and Economics (2015). As an undergrad, I had the opportunity to work on some interesting projects, ranging from maximizing athletic ticket sales to quantifying social loss related to different diseases.

LUBA Hristova - undergraduate Researcher
I am currently 3rd year undergraduate student in GIS. I have a lot of passion for GIS and the capabilities it has as a tool to visually explain different patterns and connections. I also love the outdoors, traveling, geography and everything in-between. I joined the team to discover more about social distance and the connections that occur across boarders. I'm really happy to be helping out!
I am a senior majoring in geography and minoring in horticulture and anthropology at Penn State. I have multidisciplinary interests, and my current focus is applying spatial statistics to analyze sociodemographic variables of trips.
