I'll be gradually adding more designs (and could be open to suggestions for science topics you'd like to see πŸ‘€)

Sometimes all you can do is make the world 0.0000000000001% less awful by being a good person and it feels very meaningless but it’s also the only thing that really matters

Evolution loves a crab - they've independently evolved so many times there's even a word for it (carcinisation) πŸ¦€

A three-panel comic. The first panel shows Plato saying "The definition of a human? A featherless biped." The second panel shows a robot labelled "A.I." saying "Okay, got it!" The third panel shows the A.I. robot showing an unimpressed Plato a screenshot of a security camera view of a dog in a t-shirt labelled "5:20pm Human" and declaring "Behold - a human!"

True story: if your dog is wearing a t-shirt, that's a human (confirmed by AI)

A digital illustration of a wooded hilly landscape with a river running through the middle. On the left, a burn from earlier in the dry season has left trees alive and is not eroding. On the right, a hot late dry season burn has charred the landscape, killing trees and eroding charcoal and soil into the river

Illustrating water quality challenges - this is some of my recent work showing how fire, roads & tracks, and eroding gullies can impact water quality (& how a gully can be repaired!)

A collection of graphics centred on an anthropomorphised wombat in a waistcoat, holding a magnifying glass and pocket watch, next to the text "Deep Time Detectives". The surrounding graphics include a gumtree flower, a wallaby skull, a tree, a pollen grain, a quoll, a charcoal particle, grasses, footprints, fire, and a potoroo.

A three-panel comic. The first panel shows a guy opening a door, smiling and saying "Hey, Lucy!" A label points to him that reads 'brother'. The second panel shows him leaning forward to a chocolate and white Border Collie moving towards him, as he says "Did you miss-" The final, double-width panel shows the dog rushing past him to wag her tail at a woman walking through the door behind him, labelled 'sister-in-law'. He says "...me?" and she says "Hi, Luce!"

A drawing of a top-down view of a landscape divided into two vertical panels, with a large, three-toed footprint in the centre shared across both views. The left panel shows a sandy floodplain with bushes, and the receding foot that created the footprint. The right panel shows seawater lapping and molluscs growing in and around the fossil footprint, with running shoes and a person holding a camera to take a photo of the footprint, with a scale bar beside it

I was recently commissioned to create two illustrations for The Australian Geologist, the quarterly magazine of the Geological Society of Australia

One highlights featured research, the other is just for fun!
