Mdash Editorial is the writing and editing business of Mary O’Callaghan. I’m a professional science writer and an accredited editor.
Communicating science to lay people is what I do.
My specialty areas are environmental science, natural resource management and technology, though I work across many disciplines and fields.

Communicate your science
Need a lengthy science report summarised in 2 pages?
That’s my favourite kind of work. 140 characters? Even better.
Have an idea for a science story but not sure how to tell it?
I can pitch a science story at the right level for your readers and tailor it for the medium.
Have a draft but it’s too long? Too dry? Too turgid? Too many voices? Just needs a polish?
I can edit your writing at any number of levels. Substantive editing, restructuring, copyediting, proofreading. It’s what I do.
Afraid of your work being dumbed down?
As Albert Einstein said, “As simple as possible… but not simpler.” That’s what I strive for in my writing.
Let’s challenge people with the ideas, not the writing.
“Thank you so very much for helping out with the business unit review, your help was very much appreciated and so brilliant!… you have been an absolute delight to work with and have been an enormous help providing us with your superior editing skills.”
— Anne Lynch, Communication Manager, CSIRO Land and Water
“We truly feel so incredibly lucky to have connected with Mary. Finding her was like finding a jewel.
We were searching for an experienced wordsmith to critique our scribbles. With her ‘eagle eye’ the messages have been honed and the team focused on more effective communication skills. She has guided, developed and supported our ideas by teaching us how to transform them into sparkling prose and powerful PIXELs [our e-newsletter].
We strongly recommend her and commend her professional style.”
— Dr Erwin Groeneweld, Ophthalmic Surgeon, Brisbane Eye Clinic
