COVID-19 streets: Mobility justice and the rapid rollout of pedestrian and bicyclist improvements
This research will explore the ways in which cities approached equity and public engagement in the process of planning and implementing rapid rollout pedestrian and bicycle facilities, and the impacts of those facilities, using a mobility justice framework for evaluation.

Using a Safe Systems approach to assess traffic impacts of land development
In this research we aim to demonstrate that safety can be achieved in addition to mobility benefits through the nexus between development review practices and Safe Systems, evaluate the shortcomings of existing procedures to demonstrate the gaps Safe Systems can fill, and return to communities to find implementable solutions.
