*** apologies for cross-posting *** Dear colleagues, If you know students who you think might be interested in the PhD contract offer below, could you please forward it to them? Best regards, Thomas Louail --- As part of the MELODYNAMICS project, funded by the CNRS Interdisciplinary Mission, we are seeking candidates for a PhD thesis on spatial analysis and modeling of music streaming dynamics. The thesis will be enrolled in the doctoral school "École Doctorale Physique en Ile-de-France" (ED-PIF, i.e. physics in the Paris region). The call is open to candidates holding a master's degree in physics, computer science or applied mathematics. *Project summary*: Do new songs spread like epidemics, and do we observe spatial diffusion effects? Does the size of the city we live in influence the music we listen to?  How do recommendations and network effects influence listening habits and the discoverability of songs from different geographical origins? The rise of streaming platforms, which are accessible in almost every country, offering standardized interfaces and collecting highly detailed anonymized streaming data, allows for addressing such questions empirically, and studying this important aspect of human behavior. The doctoral student will investigate the spatial dimension of listening habits and preferences, the influence and interactions of different discovery channels (platform recommendations, social networks of individuals, living environment), as well as the spatial propagation of new music on a global scale. Identifying stylized facts, building simplified models, and applying machine learning techniques will be the tools used. *Keywords*: Spatial dynamics of music listening; Spatial propagation of digital content; Spatial diffusion models; Modeling of complex social systems; Discoverability. *Full description of the projet here*: https://bit.ly/4bzrPqX *Profiles we are looking for*: Master's degree in physics, applied mathematics, or computer science, with a strong curiosity and inclination for interdisciplinary work with researchers in the humanities and social sciences. *Submission of applications*: https://emploi.cnrs.fr/Offres/Doctorant/UMR8504-THOLOU-005/Default.aspx?lang... Contact the PhD supervisors beforehand: Marc Barthelemy <marc.barthelemy@ipht.fr> and Thomas Louail <thomas.louail@cnrs.fr> *Application deadline*: June 21, 2024. Interviews will take place during the last week of June or first week of July. *Start of doctoral contract*: October 2024. -- CNRS, Géographie-cités et PACTE (associé) Campus Condorcet, Bat.rec.sud, bureau 1.152 +33 (0)1 88 12 01 27 https://cv.hal.science/tlouail
