SimWrapper

SimWrapper is the culmination of my Ph.D. thesis research: an open data visualization platform for examining outputs from MATSim and ActivitySim transport simulations.

COVID-Sim

Interactive visualizations of virus spreading through Berlin, plus dashboards for comparing results of hundreds of EpiSim simulations.

TNCs Today in SF

Visualization of Uber and Lyft pickups/dropoffs in San Francisco, part of a larger effort to understand the impacts of shared mobility on SF Streets.

AVÖV

AVÖV (Demand Responsive Transit in German) - built website and data visualizations for exploring potential to serve rural transit trips with shared autonomous taxis (site in German)
