Bart Gajderowicz completed his PhD at the University of Toronto, where he was the Social Service Simulation project director at the Centre for Social Services Engineering research group. His work focused on developing the Ontology for Social Service Needs (OSSN), and the simulation of service usage and client needs in the "Housing First" intervention program. His current work focuses on the development and adoption of the Common Impact Data Standard (CIDS) for measuring the impact of smart city services. This work incorporates the development of service-focused ontologies, data standards, AI language models, and knowledge extraction methods. With a focus on data-driven methods, Bart has applied his work in the areas of social service provisioning and impact measurement, cognitive models for simulating social behaviour, information diffusion in social networks, and identification of social factors in art market trends.
