Achilleas Psyllidis is a Postdoctoral Researcher in the areas of Spatial Data Science and Urban Analytics within the Web Information Systems group at Delft University of Technology (TU Delft). He is also Research Fellow of the Amsterdam Institute for Advanced Metropolitan Solutions (AMS), where he leads the Social Urban Data Lab (SUDL). He has 6 years of academic research experience in the identification, development, and implementation of geographically-focused data science-based solutions to help improve the understanding and forecasting of daily urban and regional dynamics. His most recent work focuses on data-driven approaches to characterizing places, as well as the activities and experiences of people in them. His research involves working with large, unstructured, and user-contributed geosocial data from a wide range of sources, with the aim to extract rich descriptions of and gain insight into the dynamics of human activities in urban places, as well as the dimensions that contribute to the character of a place. To this end, he combines spatial analysis and geographic information retrieval methods with (deep) machine learning and neural networks to build scalable pipelines and software tools that facilitate people extract knowledge from and maximize the value of unstructured data. Application domains include human mobility, transportation, spatial interaction modeling, energy consumption behavior, and facility siting. In addition to his research portfolio, he has more than 7 years’ teaching experience in urban analytics, geographic information retrieval, urban planning, and computer-aided design, at both graduate and undergraduate levels. His background is in spatial data science, urban and regional planning, and architectural engineering.    

Achilleas has co-developed SocialGlass, a web-based platform for (real-time) urban data visualisation and analytics. Moreover, he is the developer of the OSMoSys platform for linked data and ontology visualization and browsing.

He holds a PhD degree in Spatial Data Science from Delft University of Technology, having received prestigious scholarships from the A. S. Onassis Foundation, the Greek State Scholarships Foundation (IKY), and the European Social Fund of the EU, as well as individual research grants from the Foundation for Education and European Culture, and the A. G. Leventis Foundation. His dissertation focuses particularly on the spatiotemporal dynamics of human activity in cities, as inferred from different sources of large-scale geosocial data (e.g. social media). The main objective is to provide new means to enable the incorporation of heterogeneous social urban data into city analytics, and to explore the influence of emerging data sources (i.e. data from geo-enabled social media and location-based social networks, mobile phone records, and sensor data) on the understanding of cities and their dynamics.    

Achilleas also holds a Postgraduate Master's degree (MPhil) -- summa cum laude (Highest GPA among his graduating class & Highest cumulative GPA across faculties) -- in Spatial Planning, as well as a Professional Diploma (Dipl. Eng.) -- summa cum laude (Highest GPA among his graduating class) -- in Architectural Engineering, from the National Technical University of Athens (NTUA). His research on urban data integration and interlinkage has been awarded the 1st Prize for Linked Open Data for Smart Cities (2015).
