Kate Anderson
Tom Broekel
Jose Carpio-Pinedo
Kathryn Freeman Anderson is an Assistant Professor in the Department of Sociology at the University of Houston.  She received a Ph.D. from the University of Arizona in 2016.  Within sociology, she specializes in the sociology of health and illness, urban sociology, race/ethnicity, and organizations.  Her work is generally focused on understanding the social sources of health disparities in the United States.  In particular, she examines the role of race/ethnicity and urban neighborhood dynamics to analyze how these factors may affect individual health.  As it relates to urban networks, she is specifically interested in the ways that cities can be thought of as a network and examining the urban infrastructure as a network structure which can alleviate or exacerbate urban inequalities. In particular, she examines how this structure can impact access to key resources across communities and how this in turn may affect health and health care outcomes
Tom Broekel is an Associate Professor at the Department of Economic Geography (Utrecht University, NL). My work concentrates on the empirical analysis of urban regions’ economic and technological transformation, with a focus on the development and impact of knowledge networks. I study the evolution of knowledge networks within and between urban regions. The theoretical basis encompasses the sociological literature on social networks, and the so-called proximity framework from the Evolutionary Economic Geography literature. The empirical research aims at identifying factors driving their evolution and understanding their co-evolution with organizational as well as regional (economic) characteristics. Of particular interest are policy-induced knowledge networks, i.e. inter-organizational networks emerging from organizations participation in subsidized joint R&D projects. For instance, it is still largely unknown if the substitution of joint R&D projects leads to new inter-organizational collaboration or simply reinforces existing ones. For the empirical analyses, I primarily rely on patent and (joint) R&D project data, which I analyze with (ST)ERGM, RSiena, and QAP-regression models.

Javier Delso
Cesar Ducruet
Terry Friesz
Javier Delso is a PhD student at the Center of Transport Research of the Polytechnic University of Madrid. His research is focused on the effects that barriers throughout the city could have on pedestrian behaviors and movements, working with network methodologies originally developed for environmental studies. In this research, an investigation is going to be held to assess whether previous approaches used in urban networks studies could be enhanced with methodologies and indicators developed for the characterization of habitat fragmentation. Currently, a methodology that combines a network analysis tool with the environmental concept of habitat corridors is being developed. The intention of the methodology is to undergo the implementation of pedestrian corridors in a medium size city (Vitoria-Gasteiz). These pedestrian corridors are the streets that support higher rates of pedestrian movements, in which barriers for pedestrians as crosswalks and traffic lights could be removed. Other projects Javier is involved in, is the application of circuit networks and graph theoretical network methodologies to study urban network connectivity. These methods have been widely used during the last decade to investigate habitat connectivity.
César Ducruet works since 2009 as research fellow for the French National Centre for Scientific Research (CNRS) at the research laboratory UMR 8504 Géographie-Cités (Sorbonne University). His research interests as a geographer include transport networks, territorial integration, and spatial analysis, through the looking glass of urban-port development and maritime networks, with a special focus on Europe and Asia. His past experiences in South Korea (KRIHS) and The Netherlands (Erasmus University) have resulted in several collaborations with many foreign colleagues, finalised in numerous book chapters and peer-reviewed journals. He has given regular lectures in Asia (Korea, China) and Europe (Belgium, France, The Netherlands), and is currently involved in several research projects on port cities and maritime networks such as ESPON-TIGER and Marie Curie ERG (Europe), OECD (expert), and CNRS-PE/PS (France). His current research activity is the elaboration of a global vessel movement database on the 1890-2010 period, to analyse the evolution of ports, port cities, port systems, and regionalisation/globalisation processes in maritime networks. He also coordinates an informal research group on network analysis in geography in Paris.

Irina Frost
Jorge Gil
Michael Hoyler
Irina Slepukhina is a postdoctoral researcher at the Leibniz Institute for Regional geography (IfL, Leipzig). My interest in urban network analysis is focused on the historical, economic and political dimensions of the formation of city networks in globalizing post-Soviet space. In my studies I use the quantitative and qualitative research methods. On the one hand, based on the analysis of locational strategies of global service firms presenting within the post-Soviet space and employing the interlocking city network model, I am trying to uncover the network patterns among post-Soviet cities. On the other hand, utilizing qualitative research methods, I am focused on the comprehension of networking processes, which plug cities in globalizing economy. Recently I work on two topics. The first one is "External urban relations in post-Soviet space through intra-firm networks". The second is “A special regime of globalization: the case-study of Minsk”, where by means of qualitative research I am trying to shape the political and economic networks in which Minsk is embedded.
Jorge Gil is a researcher at Chalmers University, Architecture and Built Environment, at TU Delft, Department of Urbanism, and honorary research associate at the Bartlett, UCL. My primary focus has been the modelling and analysis of integrated urban network models based on open data and open source GIS technologies, applied to different fields, such as sustainable mobility, green energy, or freight transportation. These models use the mobility networks, including street networks and multimodal public transport networks, integrated with other layers, e.g. land use, socio-economics, landscape, at the highest dis-aggregation possible. Currently, my research on urban networks has two main interests: (1) the modelling and analysis of multiplex networks, using unified graph representations that integrate those levels and accommodate their idiosyncrasies, allowing their comparative analysis without resorting to different models; (2) the development of urban network typologies, at the scale of individual urban elements (streets, buildings, public transport stops), but also identifying typologies of “whole” networks such as cities, districts or public transport networks.
Michael Hoyler is reader in Human Geography at Loughborough University. My research interests are in urban economic and social geography with a particular focus on the formation of transnational networks in a globalising world. This work theorises and maps new geographies of globalised urbanisation, advancing the development of a relational approach in global urban analysis.My specific urban network research interests have focused on a) The theorisation of external urban relations as ‘central flow theory’, critically engaging with and advancing traditional central place thinking; b) The empirical study of urban networks through application of network analytical techniques at different scales and for a variety of actors including advanced producer services, media corporations, film production firms and scientists, both contemporary and historically; c) Qualitative investigations of inter-city relations to evaluate the processes behind the formation of urban economic networks, for example through interviews with key personnel in global financial and business service firms.

Alasdair Jones
Neil Hyynh Hoài Nguyên is an A*STAR International Fellow at the Institute of High Performance Computing (IHPC) in Singapore, concurrently appointed a Research Fellow at CI and a Scientist at IHPC from 2014 to 2016. He is now on leave to work at the Centre for Complexity Science at Imperial College London. As a physicist working on urban systems, I am interested in the geometrical as well as dynamical properties of the spatial and temporal structures found in those systems. The spatial structures include the morphology, e.g. street patterns, building sizes and locations, public transport system, residential distribution etc... and the temporal structures include the time evolution of the cities throughout their history of development. The study could be performed by applying various tools in statistical physics, especially complex networks due to strongly relevant presentation of network for many components existing in an urban system. These could be the transportation network, trade network or social network, etc... The analysis of these networks could reveal the functional roles and inter-dependence of elements in an urban system, whose network structure could be used to characterise the system and to make comparison among different systems and identify conditions for sustainability of a city.
Iacopo Iacopini a PhD Student at Queen Mary University of London, within the Complex Systems and Networks Research Group. My research interests include complex networks and data science, in particular, spatial networks, trade networks, social networks and urban mobility. I am particularly interested in the data driven application of network science to the urban system. My work consists of modelling and developing computational methodologies for extracting mesoscopic information from data and building mathematical models aiming to reproduce the statistical properties observed and the emerging behaviors. I am currently focusing on spatial interaction models using mobile phone data, the definition of productivity for cities, urban scaling laws, spatial segregation analysis using social media traces, coupled dynamics of complex social networks and power grids, reinforced random walks, shocks in global networks and their relationship socio-economic indicators.
Alasdair Jones is Assistant Professor in Qualitative Research Methodology and an Associate at LSE Cities. Alasdair’s research coalesces around the theme of urban life. In particular, he is interested in the relationship between built form in cities and social practices, and his published research to date has centred on public space, mobilities, and the ways that citizenship is experienced in urban settings. Alasdair is currently writing up qualitative research he has conducted that adopts a material culture approach to explore the fit between sustainable design features of masterplanned developments and the living practices of residents of those developments.

"He is also director and editor of EURE Magazine and member of the International Association of Sociology (ISA), Research Committee on Urban Sociology and Regional Development (RC21), the Ibero-American Network of Globalization Researchers And Territory (RII) and the Research Network on Metropolitan Areas of Latin America and Europe (RIDEAL) Previously he was Director of the Digital Planeo Magazine His research topics include: urban sociology, sociability networks, processes of metropolization and expansion Urban, social housing.
Xingjian Liu is currently an Assistant Professor in the Department of Urban Planning and Design, The University of Hong Kong (HKU). He is the recipient of Regional Studies Association Early Career Award (2015) and HKU Faculty of Architecture Research Output Prize (2016). He is an associate director of the Globalization and World Cities (GaWC) research network, as well as the Beijing City Lab. My urban networks research has the following themes: (1) Conceptually, I examine both 'city-regional networks' and 'networks of the city-region'. The latter relates to the unevenness of network connectivity within a pre-defined city-region, focusing particularly on those more connected localities where network externalities display most clearly. The former refers to the observed flows of information, people, and goods in city-regions, which in turn are conceptualized, mobilized, planned, and managed as an internally coherent and well-connected space. (2) Thematically, while focusing on urban economies, my research aims to shed light on social, environmental, and governance dimensions of urban networks. (3) Methodologically, I take a mixed method approach. On the one hand, I employ newly emerged data sources (e.g., big data) and analytics to characterize urban networks at multiple geographical scales and over time. On the other hand, I combine quantitative and qualitative analyses to substantiate our understanding of the causes and consequences of networked city-regions. 
Laura Lotero-Velez is an industrial Engineer from Medellín, Colombia (South America) and works as an assistant professor in Statistics for undergraduate students at the Industrial Engineering Faculty of the Universidad Pontificia Bolivariana, in Medellín. My research interests are urban mobility networks and the processes that take place through or because of this network in the city. I have been studying the mobility networks of different cities of Colombia, by using origin-destination surveys. I have analyzed them by using the multiplex approach, each layer representing the transportation mode from/to different zones of the city. I have also included socioeconomic characteristics of the people travelling, by using the so-called socioeconomic strata that is a classification of households in Colombia, regarding the utilities paying capacity as a proxy for income level. I would like to investigate how the socioeconomic division of people and their mobility patterns may affect other processes or dynamics in the city, for example how an infectious disease may spread through the city by the movement of people and to see how it propagates from one social class to the others.
Ouassim Manout
Stephen Marshall
Kirsten Martinus
Ouassim Manout is a PhD student in urban modeling at the university of Lumière Lyon 2, France, and research engineer at ForCity. His research focuses on spatial modeling issues in urban models. Space has long been considered by economists through simplistic metrics reflecting little about its complex reality. Specifically, little attention has been paid to the relationship between space and networks in urban models. Most models rely on a physical description of space and networks. Space is discretized into zones. Network is modelled as a routable graph. Due to data availability, each description has its proper level of resolution. Albeit, the two levels of resolution are interdependent. The research we conduct aims at exploring the hidden bonds existing between these two spatial objects and the possible impacts arising from a mismatched description and how to neutralize such impacts.
Stephen Marshall is Professor in Urban Morphology and Urban Design at the Bartlett School of Planning, University College London. Dr Marshall has over twenty five years’ experience in the built environment fields, initially in consultancy and subsequently in academia. His principal research interests are in urban morphology and street layout, and their relationships with urban formative processes, including urban design, coding and planning. He has written or edited several books, including Streets and Patterns (2005), Land Use and Transport (with David Banister), Cities, Design and Evolution (2009) and Urban Coding and Planning (2011). He was Chair of the Editorial Board of Urban Design and Planning (Proceedings of the Institution of Civil Engineers journal series) from its launch to 2012; and is now co-editor of Built Environment journal.
Kirsten Martinus is a Research Fellow at the Centre of Regional Development, The University of Western Australia. During 2013-16, I played a lead role in an industry-funded research agenda examining globalisation and economic development in Perth, Western Australia. My work is grounded in its multi-scale spatial focus on the uneven distribution of resources (mining, energy, innovation, wealth) as well as an understanding of the urban and socio-economic factors that increase economic competitiveness and mitigate uneven development. I employ social network analysis (SNA) to unpack flows and interactions between local economic agents (both labour and corporate) and understand how cities connect at the global scale. My research seeks to bridge disciplines of economic geography and urban studies primarily through SNA examining city competitiveness at two levels – its comparative advantage in the global economy as well as specific industry-based competitiveness. This two-scale global/local approach is novel and challenging, but I believe most likely to generate new insights and better understandings on the dynamics of Australian competitiveness within the global system.
Michiel van Meeteren
Evert Meijers
Asya Natapov
Michel van Meeteren is a postdoctoral researcher at the Brussels Centre for Urban Research. I consider myself to be an old school 'renaissance man' geographer going against the trend of hyper-specialization. My research interests cover the fields of economic, urban, financial and political geography, with a particular interest on the interstices between these subfields. My approach to these topics is polyvalent in terms of methods but is characterized by a focus on methodological rigor and a thorough historically-aware embedding in literature. My current work covers four topics. First, I have ongoing engagement with urban systems theory where I try to connect longstanding theoretical debates with new developments in data and methods. Second, I combine this with disciplinary historical research aiming to nuance and overcome some of the polemic debates and fractures that cripple geographical theorizing. Third, I study the Europeanization of financial markets in the EU and the co-evolution between firms and regulatory institutions. Fourth, I contribute to investigating the latest wave of technological innovation in finance in general (FinTech) and the Brussels economy in particular.  
Evert Meijers is an associate professor at the Faculty of Architecture and the Built Environment of Delft University of Technology, where I lead a research group on ‘urban systems and dynamics’. My contributions to, and interests in the study of urban networks concentrate on four issues: (1) Urban networks on the regional scale of polycentric urban regions; (2) Empirically and conceptually linking network embeddedness of cities (on all spatial scales, from regional to global) to their performance and the performance of the system of cities as a whole, all embodied in new concepts such as ‘borrowed size’ and ‘city network externalities’; (3) Using ‘big data’ to develop a new understanding of urban systems and urban networks; (4) The urban planning/policy implications of urban networks.
Asya Natapov is a postdoctoral researcher at the Centre for Advanced Spatial Analysis (CASA) University College London (UCL). Her interdisciplinary research links visuospatial cognition to urban dynamics. A link is made at the intersection of three technological, and practical fields: complexity science (statistical physics, graph and network theories), spatial cognition (acquisition and utilization of spatial knowledge), and smart cities (urban planning enhancing digital technologies). Commonly, modeling of urban space leans on the principles of society, economy, or politics. There are very few models based on cognition as an active player in the evolution and dynamics of space. Using a complex network approach, Asya has developed a graph-based analytical framework, which represents the relationship between built environment and urban activities, drawing on visual cognition. This framework was tested and evaluated by navigation experiments in virtual reality and real-world case studies. The overarching mission of Asya’s research is twofold: First, to illuminate aspects of human urban cognition from a network science perspective. Second, to provide effective tools for exploring various scenarios of urban sustainable design. 
Antoine Peris
Ate Poorthuis
Rossano Schiffanella
Antoine Peris is a PhD Candidate in the section of Urban and Regional Research in the faculty of Architecture and the Built Environment of TU Delft, with a focus on the external relationships of cities. My dissertation project aims to derive relevant spatial information from unstructured data and to compare and combine them with more classical data sources and models of intercity relations. I am interested in the history of urban network research, and notably how this field has evolved in relation with innovation waves coming from different disciplines such as geography, economy, sociology, physics or biology. This research is conducted through extensive readings and under the framework of quantitative epistemology (bibliometrics and text mining methods). It is the first step of my PhD project on using unconventional data derived from the web to explore the multiple relationships between cities. The fact that cities are linked together in many ways is one of my main interests concerning urban network analysis. I want to contribute to the knowledge on functional interdependencies at several scales and on the local embedding of flows between cities.
Ate Poorthuis is an Assistant Professor in the Humanities, Arts and Social Sciences at Singapore University of Technology and Design, where he heads up the Spatial Networks Lab. His research explores the possibilities and limitations of big data, through quantitative analysis and visualization, to better understand how our cities work. He is the co-founder of The DOLLY Project, a repository of billions of geolocated social media, that strives to address the difficulties of using big data within the social sciences. I believe one of the most insightful lenses on the city is relational. From gentrification, to mobility, to issues of social justice and equity, many key urban processes can be analyzed by looking at how people, institutions, technology and places are connected together. I study these connections along two axes. First, I am excited about the promise of the many new (‘big’) datasets and computing power now available to us. This allows us to revisit urban and network theories developed since the 1960s that were much more difficult to test empirically before. Second, many quantitative researchers are building models of the city that are elegant and abstract. They turn incredibly complex data into easy-to-understand patterns. While this has great academic value, for those applying this research in practice (e.g. urban planning), important details might get lost in these abstractions.
Rossano Schifanella is an Assistant Professor in Computer Science at the University of Turin, Italy, where he is a member of the Applied Research on Computational Complex Systems group. He is a visiting scientist at Nokia Bell Labs, Cambridge, and a former visiting scientist at Yahoo Labs and at the Center for Complex Networks and Systems Research at the Indiana University where he was applying computational methods to model social behaviors in online platforms. His research embraces the creative energy of a range of disciplines across technology, computational social science, data visualization, and urban informatics. He is passionate about building new mapping tools that capture the sensorial layers of a city, and designing computational frameworks to model aesthetics, creativity, and figurative language in social media. 
Nora Stambolic
Martin Tomko
Allan Watson
Nora Stambolic is a PhD candidate at the Faculty of Geosciences and Environment at the University of Lausanne, and a research associate at the Luxembourg Institute of Socio-Economic Research (LISER). Nora’s research focuses on the ways and conditions in which firm networks contribute to cross-border metropolitan integration. By focusing on the cases of city-regions of Luxembourg and Copenhagen-Malmo, she investigates the interdependency that exists between cross-border intra-firm networks, entrepreneurial strategies and institutional frameworks in which firm networks embed.
Martin Tomko is a Lecturer in Spatial Information Science, in the Department of Infrastructure Engineering of the University of Melbourne. He has fundamental research interests in understanding and supporting urban spatial communication – the way people interact in and about cities through computational approaches. The interaction between people and places is very well characterized using graph models, graph data structures allow us to capture human knowledge about space, and network processes fundamentally contribute to the spread of information and communicable diseases in the the urban environment. A recurring problem in any network-based research, as well as in any spatial research is the definition of three fundamental components: (1) the analytical atom; (2) the nature of the links between them; and (3) the granularity and its impact on the outcomes of the the analysis. In my research, I focus on cognitively grounded choices of these components. In a separate strand, I explore large-scale human interaction data to understand the nature of interactions, their temporal change, and their dependence on other contextual aspects of the agent (physical/environmental, social and cyber). In the health domain, however, the replicability of research based on large, proprietary datasets is weak, due to access restrictions on sensitive data. How does this impact on (network) science is a most pressing question. 
Allan Watson is Lecturer in Human Geography at Loughborough University. He is I a cultural-economic geographer with research interests that focus predominantly on the geographies of music and the musical economy, as well as film and media. Drawing together both geographical-relational and sociological perspectives on cultural production, labour and consumption, my research focuses on three overlapping areas of concern: (1) The nature of the new digital market place for music, including the monetisation of music, and the changing nature of music consumption; (2) Relational economies of music and media production, including the nature of local (urban and regional) and non-local knowledge sharing, business networks and production networks, and professional mobility; (3) Relational work and creative practice in music and film, including emotional labour, precarity, and the extensification and intensification of work.
Jingyan Yu
Yuerong Zhang
Jingyan Yu is a PhD student at Institute for Transport studies, University of Leeds, UK. My current research interest revolves around my PhD topic, Modelling the Evolution of Road networks. Based on the previous empirical and modelling understanding about road networks’ complex nature and structure, I study road networks’ evolution using a framework consists of three perspectives, road network evolving as a complex network, in the complex urban system and as a transport system. Following the framework, I approach road network evolution with a modelling and simulation methodology. I design generative network models to experiment with different road network evolution mechanisms and investigate interactions between road networks and urban factors of interest. I implement the models, examine the simulated network structure, and visualize them using Python language. I find that generative network models can simulate not only the network patterns similar to road networks’, but also their dynamic evolution process. I also find the richness in the topic of road network evolution because of road networks’ deep connection to the urban system.
Yuerong Zhang completed her BEng in Urban Planning and Design at Tianjin University in 2014, and went on to gain her master in Transport and City Planning in 2015 at the UCL Bartlett School of Planning. During her master studies she developed her interest in the relations between street networks and transport performance, like high traffic efficiency networks, and completed her master thesis titled “A comparison on a set of topological representations for predicting traffic flow in small-scale urban network in central London. Before returning to UCL to pursue a PhD in Planning studies, Yuerong worked as an urban designer in North-eastern Architecture Institute. Yuerong intends to further develop her academic interests in quantitative and topological understanding of street networks through spatio-temporal network analysis in aim of guiding further road planning in respect of distribution of number of roads in different road hierarchies, structural network organisations, etc.
