She has a double degree majoring in chemistry and mass communication (journalism) with a minor in radio from Murdoch University, but found she was better at telling stories than hanging out in the lab. So she ran away to Canberra to join the science circus, travelling around regional Australia presenting science shows and workshops for Questacon, while completing a graduate diploma in science communication at the Australian National University. And she can still make a mean batch of cornflour slime.

After a stint as the editor of ScienceNetwork WA with Perth science centre Scitech, she joined the ABC in 2008.

TomTom Rayner

I’m an Australian scientist turned photographer.

As a scientist, I worked for over 10 years to improve the condition of Australia’s rivers. I conducted and published high-quality research, taught graduate programs and led teams of researchers. My work generated over $1 million in funding, 18+ peer-reviewed papers with 600+ citations, two book chapters and several first-class Honours and PhD graduates.

During this time, I also pursued an interest in science communication. I studied photojournalism at The Australian Centre for Photography, produced and presented a solo photo exhibition, crowd-funded the publication of a photo book, wrote a monthly magazine column featuring my underwater images and was a semi-finalist at the Wildlife Photographer of The Year competition.

In 2015, I left academia to start my own venture. As Director of Tenure Chasers, I use my scientific expertise and award-winning photography to help young academics fix their broken communication. I also work with the non-profit group Freshwaters Illustrated, run the important fisheries website, am a Senior Associate at Science in Public, Australia’s leading science communication agency, and am Photographer in Residence at Belsize & Co.

I’m Director at Tenure Chasers and a Senior Associate at Science in Public.

JeromeJerome Pelletier (Stepping Stone Films)

Jerome was born in the French speaking part of Switzerland. At the age of 14 he discovered his father’s super 8 camera – a small oddly shaped ‘state of the art’ Bolex camera. The gadget intrigued him, as well as the opportunity it was offering. Thus began a life-long passion for creating unique and beautiful images.

In 1990 he started his professional career with the opening of Canal 1 Atelier Video in Bienne, the home of Swiss watches, with his friend and colleague Yvan Kohler. After three successful years learning his craft, he decided to explore the world and came to Australia.

It didn’t take long for Jerome to fall in love with the beautiful Australian landscape, friendly people and relaxed lifestyle. And when, soon after arriving in 1994, he fell in love with his Australian wife Linda, his fate was sealed!

In 1999 he founded Stepping Stone Films and joined the Australian Cinematographers Society (ACS) as an active member. Since then Stepping Stone Films has grown into a successful boutique production company and his talent as a Director of Photography has been recognised and acknowledged through more than 20 awards from the ACS.

Jerome has worked with Science in Public on many short videos over the years, including videos for the L’Oréal for Women in Science Fellowship program, and the CSL Florey Medal.
