Wednesday 13 October: Karen Chapple, University of Toronto
The expectation of a mass movement out of cities due to the rise of remote work associated with the Covid-19 pandemic, is counter to longstanding theories of the benefits of agglomeration economies. It suggests centrifugal shifts of economic activity that could boost neighbourhood economies at the expense of the downtown core. Using mobile phone data from SafeGraph, we track migration and daily mobility patterns throughout four U.S. metropolitan areas (Austin, New York, San Diego, and San Francisco) between July 2019 and June 2021. We find that diverse suburban centres and exurban areas have generally bounced back more quickly than dense specialized commercial districts, but outcomes vary depending on local economic structure and urban form.
Speaker bio: Karen Chapple, PhD, is the inaugural Director of the School of Cities at the University of Toronto, where she also serves as Professor in the Department of Geography and Planning. She is Professor Emerita of City & Regional Planning at the University of California, Berkeley, where she served as department chair and held the Carmel P. Friesen Chair in Urban Studies. Chapple studies inequalities in the planning, development, and governance of regions in the U.S. and Latin America, with a focus on economic development and housing.
Speaker bio: TBC
Speaker bio: I am an urban and transportation geographer and a Geographic Information Scientist. I am fascinated by cities and neighborhoods and in understanding their processes of change. I love searching for new and creative ways of visualizing and analyzing these dynamic processes – from the more complex geocomputational approaches to the simple word cloud made from real estate listings-I enjoy seeking out new data sources or methods and investigating their potentials and limitations in illuminating processes of change.
Wednesday 03 November: Professor Adam Dennett, UCL CASA
While recent debates have widely acknowledged gentrification’s varied manifestations, success in enumerating and disentangling the process and its defining features from other forms of neighbourhood change at-scale and across entire cities, has remained largely elusive. This paper addresses this gap and employs a novel, open and reproducible urban analytics approach to systematically examine the past and future trajectories of neighbourhood change using London, England, as a case-study example. Using suites of datasets relating to population, house prices and built environment development, the nature of gentrification’s mutations and its spatial patterns are extracted through a multi-stage data dimensionality reduction and classification methodology. Machine Learning is subsequently adopted to model gentrification’s observed trends and predict its future frontiers with interactive visualisation methods offering new insights into gentrification’s projected dynamics and geographies.
Speaker bio: Professor Adam Dennett is Professor of Urban Analytics and Head of Department at the Bartlett Centre for Advanced Spatial Analysis (CASA), University College London. Adam is a geographer with diverse research interests which have included in recent years, population and migration, the geographies beer and brewing in urban areas and improving our data landscapes though crowd sourcing or synthetic data approaches. He has ongoing research interests in areas such as gentrification and neighbourhood change, residential mobilities, housing, urban health and retail modelling. Has a passion for open science, reproducible methods and for applied urban science to have real world impact through collaborative endeavours with urban governments

Wednesday 19 January - CASA Seminar Series: Omar Guerrero, Alan Turing Institute
Omar Guerrero, Alan Turing Institute: Modeling Sustainable Development from the Bottom Up: Coupling Open Data and Agent Computing to Inform. This event has been arranged by CASA the Bartlett Centre for Advanced Spatial Analysis
About the talk
The explicit acknowledgement of the complexity of the Sustainable Development Goals (SDGs) is one of the main innovations of this international agenda. However, the formal analysis of complex systems in the SDG literature remains scant, as most of the focus is given to (top-down) aggregate models such as systems dynamics and networks of indicators. In this talk, I will argue that an adequate treatment of complexity needs to look at development as a bottom-up process, with macro-level outcomes emerging from micro-level interventions. From a quantitative point of view, popular methodologies such as statistical analysis and machine learning are inadequate to deal with this vertical causation since the existing data are aggregate and coarse grained (typically annual development indicators). To resolve this, models with explicit agent-level causal mechanisms are needed, and agent computing is the right tool to create them. I will present the research program of Policy Priority Inference (oguerr.com/ppi), which employs agent computing to model the SDGs from the perspective of public expenditure interventions. I will discuss several applications related to policy coherence, policy resilience, feasibility, fiscal federalism, accelerators, and bottlenecks; as well as the country-case studies in which they have been applied. This programme provides a fresh perspective to the challenges of multidimensional development, and a rigorous approach to exploit not only indicators, but also new sources such as open spending data.

Wednesday 26 January - CASA Seminar Series: Fran Meissner, University of Twente
'Migration Information Infrastructures meet urban research: how (else) should we study urban migration in times of big data'. This event has been arranged by CASA the Bartlett Centre for Advanced Spatial Analysis
About the talk
This presentation will focus on answering the question: how migration researchers should engage with research ethics in relation to the new capacities, practices, and data sources available in our current times of datafication. Starting from recent developments in migration research, the paper works towards elucidating that question for urban contexts. The question is considered through what we term a migration information infrastructures lens. This lens pays particular attention to emerging public-private configurations which produce both new data and new approaches to migration research. To get at what with ethics and migration research in times of big data, we try to illustrate the differing bases on which migration research must be judged now that it can draw on data sources and practices not available to previous generations of scholars and policy researchers.
About the Speaker
Fran Meissner at University of Twente
Fran Meissner’s main research interest is focused on contemporary urban social configurations and how – in times of datafication – these are transformed through international migration.

Wednesday 16 March - CASA Seminar Series: Agnieszka Leszczynski, University of Western Ontario
Urban platform visualities: Aesthetics, desire, communication
In this talk, I engage with platform materialities – by which I mean the observable, physical forms that platforms assume in the urban built environment – and the significance of our quotidian visual encounters with these phenomena in cities. Drawing on a range of empirical instances from North American cities, I situate and trace urban platform visualities in three registers: aesthetics, desire, and communication. Docked bikesharing infrastructure in Vancouver comprises a serialized aesthetics increasingly co-implicated with the aesthetics of gentrification at the microgeographic, or sub-neighbourhood, scale of the city. What would appear to be an incorrectly placed shared e-bike sited above a tent encampment in San Jose brings into relief conditioned desires for orderly cityscapes of platformized micromobility – and desires for the intended subjects of urban platformization – while also opening onto possibilities for their interruption. And two additional instances from Vancouver – signs indicating reserved parking for mobility platform vehicles, and stickers advertising the availability of on-demand meal delivery on a restaurant front – materially communicate the conditions of platform urbanism along axes of changing spatial and social relations in the city. I discuss this visual-material perspective nuances our understandings of the co-generative dynamics of platforms and cities by foregrounding how platforms materially make place, claim space, and mediate socio-spatial relations in urban environments.
