Gresley is a geologist. She started out in geological mapping, spent years in research, and now works in geomorphology for sustainable rangeland management. Over a 30-year career, she has taken part in geology’s move from analogue to digital: compasses to satellite navigation, Rotring pens to georeferenced image manipulation, theodolites to digital elevation models.
She’s very excited about the possibilities that drones offer in field work and remote-area land management. Gresley’s favourite part of Australia is the Australian deserts (all of them) and drylands, and when she’s not at work she volunteers as a Girl Guides unit leader.
