Professor Hughes's research focuses on energy markets, especially as applied to the transportation sector. In particular, his work investigates how consumers and firms respond to the incentives embedded in policy choices. Professor Hughes' contributions fall into three main areas: climate change and renewable energy policy; driver behavior and urban traffic congestion; and freight transportation and goods movement.
