His research aims to develop transport systems that are safe, sustainable and equitable, with a central focus on road safety in low- and middle-income countries. His recent work has focused on the development of analytical tools for improving estimates of the incidence of injuries in information-poor settings using available data sources. Kavi co-led the injury expert group of the 2010 Global Burden of Disease Project. He is formally trained as a mechanical engineer and his PhD (Cornell, 2001) thesis research focused on the mechanics of material failure, which he later applied to the study of injury biomechanics and vehicle crashworthiness. He is broadly interested in the design of products, environments, and systems that are safe and have positive health impacts.
