Media

Kirsty turns research, science and environmental stories into conversations people can understand, remember and share. She is an experienced media guest across radio, television, print, podcasts and online media, and is comfortable with live interviews, talkback, panels and longer-form conversations.

Her strengths are making complex ideas feel accessible without flattening the science, finding the human story in a topic, and bringing curiosity and warmth to the conversation.
