I’m a computer scientist and a researcher at the Industrial Engineering Department at the University of Toronto. I use ontologies and data-driven artificial intelligence (AI) methods to study how people and groups interact in complex systems. My current focus is on cities, communities, and urban centres.

See a list of my research projects ⇣ and publications ⇣.

I use AI to help organizations make smarter data-driven decisions. In my research group we create ontologies that allow for semantic interoperability between data silos. We create ETL pipelines that consolidate data in a knowledge graph, and perform data analysis on the graph. We are developing an explainable language model to extract information and build a knowledge graph for custom domains.

Recently, our team has developed a catalogue of urban datasets to help researchers find and integrate datasets from across Canada. This work resulted in a Maturity Model for urban dataset metadata.

We have an ongoing partnership with the Common Approach where we continue to evolve the Common Impact Data Standard (CIDS) for measuring impact of social purpose organizations across Canada.

I’m currently working on new tools for government agencies to measure impact, study how health information and opinions spreads online, and improve search capabilities in distributed systems.
