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.


Wednesday 20 October: Janet Chapman, Crowd2Map / Tanzania Development Trust

Speaker bio: TBC

Wednesday 27 October: Elizabeth Dellmelle, UNC Charlotte

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: Fran Meissner, University of Twente
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.

Speaker bio: 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. She is an Assistant Professor in Critical Geodata Studies and Geodata Ethics at the University of Twente. Before starting at Twente Fran was an Assistant Professor of Urban Studies at the University of Leiden. She has previously held a Marie Skłodowska Curie Fellowship at the TU Delft and a Max Weber Fellowship at the European University Institute in Florence. Fran remains a long term research partner at the Max Planck Institute for the Study of Religious and Ethnic Diversity, where she completed her PhD work as a Doctoral Research Fellow.
