Dr Hannah Critchlow

Bestselling author, broadcaster and neuroscience presenter who loves brain based chats plus jogs along the towpath…

I’m an internationally acclaimed neuroscientist based at the University of Cambridge. I love demystifying the human brain on Radio, TV and at Festivals.

I’ve helped present BBC’s Tomorrow’s World Live and BBC2 Family Brain Games, published ‘Consciousness: A Ladybird Expert Guide’ with Penguin and The Science of Fate, with Hodder in May, 2019, which made The Sunday Times Bestseller list.

In 2019 I was named by Nature as one of Cambridge University’s ‘Rising Stars in Life Sciences’ in recognition for achievements in science engagement. I was also elected member of the prestigious European Dana Alliance of the Brain and joined the judging panel for the prestigious Wellcome Trust Science book Prize for 2018.

My work in science communication saw me named as a Top 100 UK scientist by the Science Council in 2014 and one of Cambridge University’s most ‘inspirational and successful women in science’ in 2013.

During my PhD I was awarded a Cambridge University Fellowship and as an undergraduate received three University Prizes as Best Biologist.

Hannah is a top professional – diligent and easy to work with. Hannah has the ability to simplify complex neuroscience into content that is easily digestible. She delivered a fantastic session full of knowledge and practical ideas for leaders to take away and use immediately”. Brendan Barns, Founder London Business Forum

“We’ve worked with Hannah for 4 years….she has an exceptional ability to communicate complicated ideas about science and technology in a way that speaks to the general public and to schools audiences. She’s lectured about developments in neuroscience at Hay several times to audiences of 1,000 and 1,750. It’s a scale that’s challenging for most teachers. She works the space like a rockstar. Each time she has had the highest possible response rating from the audiences, both from students and from professional adults.” – Peter Florence, Director of the Hay Festival

“Hannah was one of our favourite ever speakers at 5×15- she’s dynamic, and an incredible communicator of complex and profound ideas. She wowed our audience in Hackney with her laughing rats and astounding insights into the human brain- we can’t wait for her to come back to join us again.” – Daisy Leitch: Director of 5 x 15

“Hannah has been a leading presenter at the Cambridge Science Festival for many years, and thousands of people from schools and family audiences have really enjoyed her interactive demonstration lectures. Hannah’s clear and lively communication style has brought the subject of neuroscience alive and her popular talks have received great feedback. Hannah also carried out a number of thoughtful and targeted public engagement activities with community groups including Squeaky Gate, a charity empowering people including those with mental health issues through arts and music.” – Nicky Buckley, Former Head of Public Engagement, University of Cambridge

“The human brain is one of those subjects of such forbidding complexity that anything less than a clear, engaging, approachable and intelligent talk would leave an audience staring blankly at an imponderable galaxy of neurons and synapses. Hannah Critchlow’s lecture, to several hundred A-level Biology students, more than exceeded these testing requirements. She has the rare and important quality of being able to distil even the most recondite ideas for an audience beyond the laboratory and in doing so reminding a young audience that scientific inquiry is for anyone who is curious. It’s particularly exhilarating to see a group of students being guided expertly through the great leaps in understanding made in neuroscience, to learn about the truly wondrous advances still to be made and perhaps to wonder if they could be the ones who will be making the discoveries of the future.”  – Dan Powell, Director of A’Level Science Live

“Hannah gave a talk at the How To Academy’s annual Conference on How To Change the World and she was absolutely fabulous. It was a totally inspiring talk that had the audience completely rapt. She is the most brilliant communicator of science.” – John Gordon, Director of the How to Change the World Academy

Hannah Critchlow is the most brilliantly engaging speaker. She wowed a Shambala crowd of 200 at the festival in 2018, and we couldn’t wait to have her back this year. One of our absolute highlights of last year.”– Sophie Chatz, Shambala Festival programmer
