Hi, I’m Dr Sarah McKay
I’m an Oxford University-educated neuroscientist, author, speaker and director of Think Brain's suite of online professional training programs in brain health and applied neuroscience.
I live on Sydney’s Northern Beaches, Australia, where I write, teach, swim in the ocean year-round, and run programs that translate cutting-edge brain science into practical tools for health and helping professionals around the world.
My first book, The Women's Brain Book: The Neuroscience of Health, Hormones and Happiness was published in 2018.
My second book, Baby Brain: The Surprising Neuroscience of How Pregnancy and Motherhood Sculpt Our Brains and Change Our Minds (for the better) was published in April 2023.
My third book Brain Health For Dummies will was published by the iconic yellow and black "For Dummies" brand in 2025.
Work with me.
d. Keynote Speaker
I am an experienced keynote speaker presenting to audiences including TikTok-Australia, EY, Vogue, Winona School, Business Chicks, CalmBirth and the Resolution Institute.
My talks explore the neurobiology of uncertainty, brain-to-brain synchrony and trust, and the practical application of neuroscience in leadership, HR, and health.
I also have a special interest on women's brain health, covering how the brain changes during puberty, pregnancy, and menopause.
For professional audiences, I provide actionable tools and strategies for clinics, classrooms, and corporations. For general audiences, I translate complex brain science into relatable, engaging stories.
I offer tailored keynotes, workshops, book talks and engaging Q&A sessions, delivered either in person or virtually, to meet the specific needs of your audience.
“I have known Sarah since we were graduate students. She was always an extremely sharp thinker about science; she liked to challenge things but with an openness to possibility. It's hard to maintain sharp-edged curiosity without becoming cynical. Sarah did that as a graduate student, and she does that now.”
Professor Andrew Huberman, Huberman Lab Podcast.

f. The Women's Brain Book:
The Neuroscience of Health, Hormones and Happiness
As women, understanding how your brain is sculpted by many factors — including genes and hormones, life experiences, society and culture, thoughts, feelings, and personal beliefs — is key to better health and well-being.
The story begins in the womb and takes a fascinating, informative, and truly eye-opening journey through infancy and girlhood, puberty and the menstrual cycle, the teenage years, mental health, pregnancy and motherhood, menopause, and finally, into old age.
Learn exactly what happens inside your brain and body as you move through all of the important phases of your lives and the unique — and often misunderstood — effects of female biology and hormones.
Fully revised 2nd edition due 2025!
Due to the rapid pace (it was a long time coming!) of women's brain health research, a comprehensive updated 2nd edition of The Women's Brain Book will be released in July 2025.
