Dr Steph McLennan is a geoscientist and communicator, working to understand environmental impacts on ice-free areas of Antarctica. These environments are particularly vulnerable to damage from infrastructure development and tourism and can be incredibly slow to recover. She uses geomorphic mapping, soil science, and technology like drones to understand the landscape and environmental impacts. Like a doctor trying to diagnose and monitor disease, she is developing methods to monitor the effects of walking tracks and vehicles in remote, fragile parts of Antarctica.

Steph was awarded her PhD from the University of Adelaide in 2016 with the Deep Exploration Technologies Cooperative Research Centre, developing novel mineral exploration methods. She joined Geoscience Australia's graduate program in 2015 and has been working in the Marine & Antarctic Geoscience team since 2016, including as Chief Investigator on an Australian Antarctic Science Program project, leading two field seasons based at Davis Station, Antarctica.

She is passionate about the value of earth science to Australians. Through her outreach and media engagement, she aims to spark wonder in earth science, its relevance to everyday life, and its role addressing current and future challenges.
