Achilleas Psyllidis is an Assistant Professor of Urban Mobility and the Director of the Urban Analytics Lab at Delft University of Technology. He also leads the Social Urban Data Lab at Amsterdam Institute for Advanced Metropolitan Solutions and is an LDE Centre for BOLD Cities affiliate. He is a member of TU Delft's Transport & Mobility Institute and the Mobility Futures Vision Team. He serves on the Executive Board of Computational Urban Planning and Urban Management (CUPUM). His research explores accessibility, walkability, land use dynamics, and travel behaviour across diverse populations. He has developed innovative computational methods to analyse access equity, spatial segregation, and human mobility. He leads projects on sustainable urban mobility, accessibility, and environmental exposures. His research is funded by the EU, NWO, KNAW, SSHRC Canada, and FAPESP Brazil.

Before joining the Department of Sustainable Design Engineering, he held a postdoctoral position in Urban Data Science within the Web Information Systems group at the Faculty of Electrical Engineering, Mathematics, and Computer Science, TU Delft.

He holds an Engineering Diploma (Summa Cum Laude) in Architectural Engineering with a focus on urban planning and a Master of Science degree (Summa Cum Laude, Highest GPA) in Spatial Planning from the National Technical University of Athens. He earned his PhD in Spatial Data Science from TU Delft, Faculty of Architecture and the Built Environment. During his doctoral studies, he was affiliated with the Joint Research Center for Spatial Information between TU Delft and Wuhan University, as well as the Joint Research Center for Urban Systems and Environment between TU Delft and South China University of Technology.

He is a scholar of the Onassis Foundation, the European Union Social Fund, the Greek State Scholarships Foundation, the Foundation for Education and European Culture, and the A.G. Leventis Foundation.
