By day, I'm a researcher / master's student at the University of Toronto working in the areas of urban geography, transportation, and (spatial) data science. See Google Scholar for links to papers and reports.
My side projects usually involve cartography and data visualization using a variety of open-source tools (often with Python, R, JS, PostGIS, and/or QGIS). Some of these projects are hosted on GitHub. See below for links to a few.
