lydiaLydia Hales

Lydia is a science writer and project manager. She is Senior Science Editor at Science in Public, and a freelance science journalist.
Lydia has been published by Australian Geographic, The Guardian Australia, ABC Online, The South China Morning Post, The Age, Cosmos magazine, and others. She has also written book reviews for Science Book a Day.

She once had a poem non-delinquently published on a tree. This joined others’ work in an anthology to raise funds for Tasmanian Devil Facial Tumour Disease research, as part of Tasmanian Living Writers’ Week.  She has had creative writing in a few other small anthologies, and volunteered at the Melbourne Writers Festival and Emerging Writers’ Festival in 2013 and 2014.

She moved from Tasmania in 2009 to study Science (Marine Biology and Zoology) at James Cook University in Townsville, finishing with a small research project in the rainforest in Borneo. She then moved to Melbourne to complete a Master in Journalism. Prior to joining Science in Public, she held a temporary media and communications role at the Burnet Institute, writing for their website and providing assistance during the International AIDS Conference.

SuzannahSuzannah Lyons

Suzannah is a science writer and communicator, and joins Science in Public after working as a journalist and digital producer for more than 10 years, with the ABC and science news website ScienceNetwork WA.

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.

Suzannah has worked for ABC Science Online, Catalyst, ABC Health & Wellbeing, ABC Open, ABC Emergency and ABC International in Sydney, Melbourne and Albany on the south coast of Western Australia. She has produced content that was published online, and broadcast on radio and TV, some of which was also translated into Bahasa Indonesia and Chinese and syndicated across the Asia-Pacific.

At Science in Public she’s currently writing, tweeting and more for the Faculty of Science and Engineering at Macquarie University, helping them to raise the profile of their science and researchers. She’s also finding and telling the stories of 100 years of chemistry in Australia for RACI’s National Centenary Conference.

Rachael Vorwerk

Rachael is a science communicator and has come from CSIRO where she worked in the Manufacturing business unit, then internal and enterprise team. During her time at CSIRO she wrote about how scientists cooked up the strongest material on earth (graphene) with the humble soybean, how overeating is a form of food waste, and clarified myths about the cold and flu in a quiz that got over 8000 responses.

Rachael has been published in an environmental decision-making magazine ‘Decision Point’ and Double Helix, the CSIRO magazine for kids. Her stories have also been published in BBC World News, ABC news online and The Age.

She’s completed a science degree in ecology and zoology and more recently a Masters of Communication at RMIT. Rachael has a keen interest in the way that communication can bring about behaviour change – specifically environmental communication. She spent the final year of her masters analysing the way ABC’s War on Waste promoted behaviour change in Australia’s millennial generation – specifically in their use of reusable BYO coffee cups. Why did they adopt the KeepCup behaviour more than composting, separating their food waste from their general waste, or returning plastic bags to the supermarket for recycling? If you’re interested in the answer, she’d be more than happy to chat.

She’s also interned in Fiji at Save the Children, and made a documentary about Cyclone Winston, that hit Fiji in 2016. In her spare time she likes playing tennis, the flute, and going on holidays.

MichaelMichael Lucy

Michael is a science writer, editor and journalist.

Before journalism, he edited textbooks, subedited academic journals and worked in communications on an agricultural research station in Tonga.

He was an editor for several years at current affairs magazine The Monthly, where he wrote about science and politics, and comes to Science in Public after a stint as features editor at Cosmos.

Michael holds a science degree with honours in nuclear physics and a graduate diploma in creative arts, for balance.

Marisa Cardoso

Marisa Cardoso is a marketing and external relations specialist with a passion for science.

Marisa has over 14 years of experience in developing and pursuing global business opportunities in the university sector. This experience includes leading the external relations team in the science faculty at UNSW.

  • filming the UNSW Science Alumni series highlighting the varied careers scientists enter after graduating from university
  • developing the Art of Science Gallery at UNSW which showcases incredible photos related to science taken by the general public.

Her collegiate and collaborative approach to working with partners has resulted in interviews with Jane Goodall, Neil DeGrasse Tyson, Brian Greene, and Lisa Randall through Think Inc, running workshops and lectures with New Scientist, media training for up and coming researchers across NSW with Science in Public and running the successful Women on Mars event at the Sydney Opera House.

Her work with younger audiences includes running a three day Science Challenge in Indonesia where nearly 100 students from 27 high schools ran 15 experiments including building and launching water rockets off a remote beach, running a roadshow with the Australian Museum taking science to 500 students from low socio-economic schools between Sydney and Broken Hill, putting 50 students from the ASPIRE program in front of Neil DeGrasse Tyson and working with UNESCO in Hong Kong on summer school programs.

With a strong view that science should be accessible to as broad and diverse an audience as possible, Marisa enjoys working with scientists and organisations to promote greater scientific literacy and engagement with science across the globe.

Marisa holds a Bachelor of Arts (Hons) in English Literature and Language from the University of Leeds in the UK, a Master in International Law and International Relations from UNSW Sydney, and has completed the General Manager’s Program as part of the executive education program at the Australian Graduate School of Management (AGSM).

So she joined Editors Victoria (the state branch of IPEd, the Institute of Professional Editors) and was promptly appointed their newsletter editor. She currently volunteers on the Editors Victoria executive committee as communication officer.

Her freelance work gives Margie the pleasure of wrangling text into shape (both the words and formatting) and removing jargon and waffle to present scientific information clearly and directly.

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.
