Dr Poppy Gibson
I am a Doctor of Education (EdD) and work as a Lecturer in Education at a UK university. I have been teaching and coaching for 19 years and i am passionate about helping everyone grow and recognise their strengths, whatever their age.
With a background in primary teaching, I now focus my research on the areas of mental health, wellbeing, and neurodiversity. Education threads not just through our academic attainment, but also through everything we do in our lives; educating ourselves about being both physically and mentally well is vital to have the happiest lives we can.
I am currently working on exciting funded bids around neurodiversity in both the UK and Indonesia, and this research helps me continue to learn and grow as both an educator, and a neurodivergent person myself with ADHD.
Surviving sepsis in 2014 helped me change my whole perspective on life and develop a healthy daily mindset; let me help support you to do the same.
