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!)

These were created for my work with TropWATER & their collab with the Cape York Water Quality Partnership #SciArt

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

A digital illustration showing a creek crossing a dirt road, with rain eroding channels into the road, forming a downstream gully and releasing soil in to the river below

A two-panel illustration showing an eroded alluvial gully releasing dirty water and a remediated gully, covered in vegetation with a rock chute to channel the water flow

Introducing Deep Time Detectives! 🔎

Deep Time Detectives is an educational resource developed by CABAH on Australia's deep history, featuring a series of animated videos. I drew a collection of original illustrations and animated elements for these videos #SciComm

emmarehn.com/portfolio/de...

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.

My dog definitely plays favourites 🐾

#comic #BorderCollie

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!"

Live-sketches from COCE 2025 🌱

This week, I attended & presented online as part of the Conference on Communication and Environment

There were so many great sessions & discussions - I drew these live-sketches during all of the hybrid and virtual sessions I attended! #scicomm #sciart #livesketch

A collection of 16 digital sketches on a white background, summarising sessions from an environmental communication conference featuring plants, animals, and people.

Such an amazing effort! Very deserving of a celebratory puffin

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!

A cartoon showing hands holding a phone displaying an app titled "relative dating", subtitled "Find your fossil assemblage". The app shows a fossil fish, fern, and three-toed footprint captioned "Upper Jurassic 161.5 - 143.1 Ma". Buttons below the caption read "Not for me" and "It's a match!"

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

Today is the International Day of Women and Girls in Science! 🧪

To celebrate at my work, I asked some of the brilliant researchers I work with about their experiences in science - and their passion for it really shines through

Like Micha, I was lucky enough to receive an AINSE PGRA during my PhD, and I second Micha's recommendation to apply!

A great opportunity for Aus/NZ PhD students who could benefit from using ANSTO facilities for their research, such as radiocarbon and lead-210 dating labs #AcademicSky

That sounds like a very cool, and challenging, job!

I hope you like this sketch inspired by the scale of global to personal in your work

Dr Emma Rehn @bluerehn.bsky.social · Jan 28

That's okay, you can share your area of work expertise without it being research! (If you want to, no pressure)

Dr Emma Rehn @bluerehn.bsky.social · Jan 27

That's a cute one! Just a note that you need to be following me if you'd like a cartoon - but no worries if you're here just for the exchange of spiders! 🕷️

Dr Emma Rehn @bluerehn.bsky.social · Jan 27

Those who have followed me since days of yore might remember I did free sketches like this back in 2021 for science folks on Twitter

You can see all of those sketches (including spider friend in the post above, drawn for @spiderdaynightlive.bsky.social) here: emmarehn.com/portfolio/tw...

Twitter Science Cartoons

In October 2021, I tweeted an offer: any scientist could comment with a few words on their work and themselves, and I’d draw them a cartoon. Over one week, I drew cartoons for 35 scientists a…

This week, I'm celebrating reaching 1k followers! 🎉

If you follow me: comment with a few words about your research/area of expertise and some things you enjoy - and I'll sketch a little cartoon for you
