Khanna obtained her PhD and MS from the University of California, Berkeley. For research, she has worked on diverse topics ranging from technology adoption and agro-environmental policy analysis, voluntary approaches to environmental protection and the land use, market and greenhouse gas implications of biofuels. Her work on technology adoption seeks to provide a rationale for the often-observed low rates of adoption of efficiency-enhancing technologies and shows the importance of considering heterogeneous producer characteristics, risks, uncertainty and market failures that distort prices while analyzing the incentives to adopt these technologies. Khanna also examines the design of conservation payments to induce the adoption of improved land management practices to reduce non-point pollution from agriculture and enhance soil carbon sequestration.
