Algorithms for urban simulation.
I developed algorithms and furthered data visualizations for the Andorra project in the City Science Group (then Changing Places). I utilized Call Detail Record (CDR) data and developed a weighted voronoi algorithm to better distribute flows of people in more realistic ways based off the data and urban structure of the city. I also contributed to the data visualization codebase and integrated my algorihtm and some user interface elements.
I left this project in 2016 but it is still ongoing at City Science.
