Achilleas Psyllidis

I am a Postdoctoral Researcher in Urban Data Science within the Web Information Systems group at Delft University of Technology (TU Delft). I am also a Research Fellow of the Amsterdam Institute for Advanced Metropolitan Solutions (AMS), acting as research and project lead for the Social Urban Data Lab (SUDL).

My research has developed from a substantive interest in understanding how human interactions evolve within urban systems and their hierarchies, at various spatial, social, and temporal scales. To this end, I have designed and developed pioneering spatial data science methods and technologies for the creation, enrichment, integration, analysis, and visualisation of dynamic geo-social data. My most recent work focuses on the application of machine learning and neural networks to the analysis and modelling of issues pertaining to human mobility, transportation, and spatial interactions. 

Driven by the paradigm of GeoComputation in spatial analysis, I use large-scale geo-social data – primarily from social media platforms and other web sources – and apply advanced spatial data mining techniques to revisit geographical problems relating to regionalisation, social area analysis, and place characterisation.

In association with the above research line, I engage in the development of SocialGlass.
