Catherine Trudelle

Catherine Trudelle holds a Ph.D. in Land Use Planning and Regional Development, with a specialization in social, political, and urban geography, from Université Laval (2005). She also earned a Master’s degree in the same field from Université Laval (2000) and a Bachelor of Science in Geography with a specialization in marine environments from Université du Québec à Rimouski (1998).

During her doctoral studies, she completed a research internship at the University of British Columbia in Vancouver (2002), under the supervision of Professor David Ley, Canada Research Chair in Geography and Director of the Vancouver Centre of Excellence: Metropolis Project.

Following her doctorate, Dr. Trudelle pursued two postdoctoral fellowships: the first in Sociology at Stanford University, California (2006), through the Fulbright Canada–U.S. Program, and the second in Geography at Université du Québec à Montréal (2007).

Her research focuses on social and urban geography, with particular interest in urban conflicts, socio-environmental and socio-ecological disputes, and citizen mobilization.

Stefan Steiniger

Stefan Steiniger is a Geographic Information Specialist with extensive experience in leading development teams to build web platforms and applications for the visualization and collection of geospatial information. He currently serves as Product Owner for three platforms: the CEDEUS Municipal Urban Dashboard, which features 30 sustainability indicators; Walkability.App (now WalkableStreet.App), designed to capture pedestrians’ walking experiences; and CiudadCaminable.com, an open-source WalkScore tool for Chile.

Since 2022, he has been a Senior Lecturer at the Pontificia Universidad Católica de Valparaíso, where he teaches geographic information technologies and urban mobility to younger generations. His research interests include urban sustainability indicators to assess the impacts of policy changes, and he has actively collaborated on the development of mobility policies for more sustainable and livable cities, including contributions during Chile’s hosting of COP25 and through his role at the Walk21 Foundation. In previous years, he contributed as both developer and manager to the free and open-source GIS OpenJUMP, and acted as Product Owner and Technical Lead for the OIRM Platform, an urban indicator dashboard created for the regional government of Santiago, Chile.

Between 2017 and 2024, he co-led the CEDEUS “Observatory” GeoInformation Team, composed of four geographic information analysts, two software developers, and one designer, overseeing the development of the CEDEUS Municipal Dashboard and Walkability.App. From 2018 to 2024, he also served as a Walk21 Foundation Associate, where he was responsible for the development of Walkability.App, a global tool promoting street redesign to ensure safe, pleasant, and accessible walking environments for families.
