Gabriel's research interests relate to travel pattern and user behaviour analysis in urban transit networks. Using large smartcard datasets, he develops methods to understand and quantify regularity in users’ travel routines, and working to identify and investigate different types of public transport users. Gabriel earned his bachelor’s degree in Civil Engineering and Applied Sciences from McGill University, where he was also the recipient of the British Science Association Medal. He earned his Master of Science in Transportation from MIT in 2015. His all-time favorite transit line is the Victoria line in London.
