Joining Remote Sensing and Social Media Data for Migration Research – Perspectives on Cities and Mobilities

November 21, 2025

Talk, Max Planck Institute for Security and Privacy, Bochum, Germany

Together with R. Rodriguez from the Geolingual Studies team, I had the opportunity to present our research at the Max Planck Institute for Security and Privacy in Bochum, Germany. We presented research on combining remote sensing and social media data to study migration. My talk specifically highlighted our approach of combining remote sensing and social media data in research of human mobility and urban discourse across different urban environments in Africa. I am grateful to the MPISP for giving us the opportunity to visit their lab and discuss challenges and potentials for future research in this field.

Talk, Max Planck Institute for Demographic Research, Rostock, Germany

In April, I had the opportunity to present in the Seminar of the Max Planck Institute for Demographic Research, a leading demographic research center in Rostock. I am very grateful to the MPIDR for inviting and hosting me at their institute and the many inspiring discussions regarding synergies between Earth Observation and Demographic research. For more information, see the post on the MPIDR website.

Talk, Vortragsreihe der Geografischen Gesellschaft Würzburg, Würzburg, Deutschland

A. Droin and I had the special privilege of being invited by the student’s board of the Geographic Institute to hold a talk at the lecture series of the Geografische Gesellschaft Würzburg. In our talk and the following discussion, we tackled the question of how the perspectives and needs of individuals can be accounted for in urban analysis. We discussed aspects of accessibility, spatial cognition, urban functions and the use of social media, among others. You can read more on the EORC Blog post.
