Hi, I’m Jen!


I am so pleased you are here.

It is my mission to bring you science-backed education and tools so you can psychologically thrive, and feel happier, in motherhood.

Here’s a little bit about me and my qualifications, so you can be certain you are learning from an accredited and highly-specialised expert.

I’m Dr Jennifer Hacker Pearson.

I hold a PhD in Medicine (Neuroscience) and a postgraduate diploma in Psychotherapy. I am also an accredited meditation teacher, postpartum and neuroplasticity* researcher, best-selling author, international speaker and podcast host.

Most importantly, I am “Mama” to my 3 kids. That’s my favourite title and still my most challenging one.


Motherhood has tested me in many ways. Not just the part of mothering my children, and learning how to thrive in that role, but how becoming a mother changed me.

Only after my babies were born, and I learned about the power and paradox of motherhood first-hand, did it become clear to me that when a baby is born, a mother is born.

Matrescence – the term used to describe this transformation of becoming a mother (the birth of the mother) – was not in my vocabulary until matrescence hit me in the face, at force. There was no way to avoid it (and trust me I tried!).


So, I learned about it.

I learned about myself – the “new” me – the mother, and the postpartum process (including matrescence).

In particular I became really curious about how a woman’s brain changes when she becomes a mother and what role this plays in your postpartum experience.


As an aside, I learned about the brain for years before I had children. My neuroscience medical research was published in some of the top peer-reviewed journals including Nature Neuroscience and Neuroscience.


Turns out a woman’s brain changes A LOT when she becomes a mother, as does her mind.
Because a mother’s brain is extremely plastic* (adaptable).

These matrescence brain changes, and your brain to that point in your life, will lead to your own unique postpartum experience. That is due to, among other things, your DNA, your history and your individual neurobiological makeup. So, in order to thrive in motherhood, it is vital to learn about matrescence, and how becoming a mother changesyou.


Most importantly, I want you to know, that with my unique blend of science-backed education and tools you can train your brain and mind to psychologically thrive in motherhood, and feel happier.


Here is what I teach you to psychologically thrive in postpartum:

  1. All about the science of matrescence – the transition you go through when you become a mother – and how you change when you enter matrescence
  2. How your brain and mind change during matrescence, and how this changes how you feel. 
  3. How these changes affect you, personally, and your experience in postpartum. 
  4. Simple, science-backed techniques, to teach your brain and mind to thrive in motherhood.



*Neuroplasticity is the ability of the brain to change itself in structure and function due to our actions and experiences.

Dr Jen has been FEATured in…


I was born in Munich, Germany and lived there until I was 10 years old.



1987- Mum, my brother and I move to Australia and settle in Byron Bay – tough life!
1995 – Graduate from High School. I was 18 and knew everything. Ha ha ha!
1996 –  Work abroad and travel the world. I realise I know nothing.
1997 – Move to Sydney to attend University.
I planned to stay 3 years…
2009 – Leave University with three degrees including a PhD in Medicine (Neuroscience & Pharmacology) and 1st class honours in the same.
2009 – After 4 years of dating, I marry Marcus. Best decision of my life (except when he doesn’t do the dishes)
2010 – Daniel is born and my life changes forever – The I Wish Someone Had Told Me… journey begins. Accidentally.
2012 – Jake joins our family.
IWSHTM… becomes a more serious project as I realise how important its information is.
2014 – Everly, our baby girl, arrives. She challenges me in ways I have never experienced.
IWSHTM now becomes a must.
2016 – After 6 years of research and writing, including
interviewing 1000 mothers from around the world, 
IWSHTM… is released to rave reviews.
We leave Sydney after 20 years (it was meant to be 3!) and move to Auckland, New Zealand, for new adventures.
2018 – Complete Graduate Diploma in Psychotherapy. This adds so much to my mind-brain-body-life connection knowledge.
2018 – DrJen.com.au is born. Teaching mothers how to psychologically thrive in postpartum is what I live for.
2019 – Join the board of not for profit organisation PTSD Help NZ, as their Neuroscience expert and adviser.
2020 – After 4 adventurous years in NZ we move back to Australia. This time to sunny Queensland.

I’d love to hear your story.
