My research team is working on new ways to manage the interactions between urban infrastructure and environmental networks. We are also rethinking how to finance, design, deliver, and manage infrastructure systems so that they are sustainable over the long term.

We study two major challenges that face researchers and policy makers when it comes to balancing our transportation demands with air quality goals: 1) modeling microenvironment air quality, especially near roadways, and 2) clean diesel strategies.

In a public-private partnership (PPP), the government and private business work together on the construction, operation, and management of infrastructure, sharing revenue, risk, and technology. To help policy makers identify projects suitable for a PPP, we take a comprehensive systems approach that considers social sustainability, environmental sustainability, and financial sustainability.

This, we believe, amounts to an infrastructure paradigm failure. We aim for a set of general principles and methods to remedy this failure, rooted in systems theory, for application in future infrastructure system development.
