About Me

Debraj  is a computational scientist with a passion to understand urban processes (particularly complex interactions) through the use of modelling, simulation and other computational techniques.  He completed his PhD in 2017 titled ' Modelling Slum Dynamics Using an Integrated Agent-Based Simulation Framework'  at the Nanyang Technological University, Singapore.  As a postdoctoral fellow at the University of Amsterdam, Debraj focussed on validating spatial agent-based models using very high-resolution satellite imagery.  He is currently an Assistant Professor at the  Department of Governance and Technology for Sustainability at the University of Twente.

Research

Debraj does research in Spatial Modelling, Population Dynamics, Computational Sociology, Social Choice Theory and Complexity Science. He completed his PhD in 2017 titled 'Modelling Slum Dynamics Using an Integrated Agent-Based Simulation Framework'. He specifically employs agent-based modelling (ABM), statistical modelling and geographic information system (GIS) to study these systemsTo calibrate and validate these models, Debraj has applied methods from remote sensing, spatial statistics and information theory. The most significant contribution of his PhD is the new insights into how population dynamics and social network drives the growth and resilience of slums.

As a postdoctoral fellow at the University of Amsterdam, Debraj focussed on validating spatial agent-based models using very high-resolution satellite imagery from Bangalore. He has worked on understanding segregation in the slum of Bangalore using Tilly's theory of group identity. Further, his research also included an analysis of gender-preference and fertility behaviour in India. He has been active in the open exchange of data and models for the scientific community and dissemination of research results to the general public (Open Science).
