Diane began her career in sound presenting a monthly jazz music show - Modern Jazz from the Mesas on KUYI the community radio station of the Hopi Indian tribe in Northern Arizona. Her first radio feature for NPR member station KNAU Arizona Public Radio won an Edward R Murrow award for 'Best Use of Sound', while her first BBC Radio 4 feature 'When the Whistle Blows' an evocative portrait of the American freight train horn, won critical praise in the UK daily press. Diane brings 20 years experience as a research scientist and project manager to her work. In the past, she has studied topics as diverse as urban ecology and biodiversity, global carbon cycling and the wildlife of the Scottish Highlands. She also writes radio scripts and articles about science and the environment for local press.
