Research (Ongoing)

This project estimates the exposure efficiency of electric vehicles relative to their gasoline and diesel counterparts in China, using an intake fraction methodology, comparing emissions from power plants and tailpipes. From here, we extend the analysis to identify the

public health impacts of PM2.5 emissions from both e-vehicles and ICE vehicles. This research involved collaboration with University of Minnesota (Julian Marshall) and Tsinghua University (Ye Wu)(Energy Foundation)

This project developed stated preference choice experiments for future two-wheeler purchasers and identified what factors they valued in a vehicle. From this analysis, we could identify potential markets

for e-scooters in gasoline scooter dominated cities of Hanoi, Vietnam and Ahmedabad, India. This project included  collaborative efforts with Hanoi University of Transport and Communications and the Center from Environmental Planning and Technology, Ahmedabad.  Luke Jones (Economics PhD candidate) worked on this project.  (Asian Development Bank)

This research analyzes the environmental performance of e-bikes relative to other competing modes, their market potential, and the viability of alternative battery technologies. It also frames the role

of e-bikes in the PRC’s transportation system and recommends policy for decision makers in the PRC’s

central and municipal governments. Collaboration with Tsinghua University (Yang Xinmiao) and University of California, Davis (Jonathan Weinert) (Asian Development Bank)

It took decades to reach the first billion computers. It is expected that 1.4 billion more will be sold before the end of 2015. Many of these will be distributed to the poorest individuals through philanthropic organizations. It is expected that those without electricity will power their computers with lead batteries. This research quantifies some of the effects of this transition in terms of lead pollution in developing countries.

My dissertation research investigated some of the policies leading to strong e-bike growth in China, some of the mobility advantages, behavioral aspects of e-bike use, environmental impacts and ultimately safety. This research resulted in several publications and follow-up research (Volvo Foundation, National Science Foundation)

We use simulation techniques to investigate performance and safety impacts of various managed lane configurations. Moreover, we survey truck drivers and identify feasible configurations from their perspective. Overall, significant safety gains can be had in urban areas with high truck traffic by managing lanes more effectively. Conducted with Adebola Adelakun (MS Civil Engineering).
