Electrifying trucks would significantly reduce tailpipe emissions in India
With battery advances, it’s time to transition trucks from diesel to electric, researchers say
By 2050, the phrase “the motor of the economy” might be more apt than “the engine of the economy.” For now, however, the conventional wisdom[1] on electric vehicles is that batteries are costly, people worry about running out of charge during occasional long trips, and that they are naturally impractical for regular heavy users such as commercial auto fleets (taxis, ridehailing vehicles) and trucks.
My research interests lie in using a combination of modeling and empirical survey-based research to show that the converse is true, and in identifying novel policies that can take advantage of the smart devices that pervade our lives for a faster, cheaper and socially equitable adoption of clean technologies.
- Assessment of techno-economic and environmental potential and the barriers to adoption
This line of work use exploits a combination of simple spreadsheet models, the tools of industrial ecology and life cycle assessment, and surveys to isolate the critical variables driving the socio-economic and environmental impact of EV adoption.

- Estimating charging infrastructure needs and environmental impacts of fleet electrification
This project is focused estimating the charging infrastructure needs for cars, city buses, inter-city buses and long-haul trucks in different geographic regions: New York, San Francisco, New Delhi and the state of California as a whole. Data on actual taxi trips, public transit bus schedules and freight movement along highway is being used to simulate these trips using electric vehicles and estimate the minimum charging infrastructure, the cost of service and environmental impacts without sacrificing timely movement of people, goods and services.

- Industrial Ecology and Life Cycle Assessment
Life cycle assessment (LCA) is a widely utilized technique to quantify inputs
and emissions associated with the life cycle of a product, from raw materials
extraction through the product’s end-of-life. In a globalized world, LCA can be a powerful framework to inform and enable voluntary action by individuals, businesses and governments to reduce pollution that arises because of variation in the stringency of environmental policies and regulations across different political jurisdictions worldwide.

For a long time — and for reasons both good and bad — society’s approach to clean technologies has been to help those who can afford to pay adopt and, in doing so, induce learning and large scale production that drive costs down so that eventually everyone can adopt them.
Modern information and communication technology allow us to more precisely target and tailor incentives and information to specific groups of individuals and households so clean technologies can be adopted more efficiently using less public subsidies. Some examples of our work in this area:
