Jon Eaton


Jon has marketing, brand and digital background with experience in the healthcare sector. He is currently Director of Communications and Digital Engagement at Epilepsy Action.

Jon said: I help organisations to grow and change using marketing strategy and digital technology and feel I can use these skills to support the BTF achieve its goals.


Professor Marian Ludgate

Marian is a retired research scientist (Professor Emerita in Molecular Endocrinology). Her career has been dedicated to the investigation of all aspects of the thyroid gland and to a range of thyroid disorders and accompanying conditions, such as thyroid eye disease. 

Over this time, Marian has worked in research centres in Cardiff and Brussels. She has also been involved in projects funded by our BTF Research Award and continues to be involved in thyroid research.

Marian says: As a research scientist I have been involved with patient support groups. I am keen to maintain and extend this relationship and hope to 'put a bit back' after benefitting from it throughout my career. In addition, several close family members have been diagnosed with thyroid problems, including cancer, hence I have some understanding of the anguish that can accompany these disorders.

Kasia Jones

After graduating with a BSc, Kasia qualified as a Chartered Management Accountant.  She has worked at a variety of commercial enterprises and most recently at a small charity supporting engineers. Kasia said:

I was diagnosed with hypothyroidism in my early 30s, following changes in my energy levels and weight. I was fortunate to be diagnosed in the early stages of the condition which meant my symptoms were managed from the onset. I came across BTF around the same time when looking for answers. I am grateful for their support and ongoing initiatives, especially when I fell pregnant with my son. 

I hope that I can bring my patient and professional charity experience together and assist the BTF in achieving its vision.

Anna Reavell 

Anna is a veterinary surgeon working in a small animal practice. Prior to studying veterinary medicine at Wolfson College Cambridge, she read psychology at Loughborough University. She also has a post-graduate diploma in Companion Animal Behaviour Counselling from Southampton University.

Anna was diagnosed with hypothyroidism after the birth of her second child who was diagnosed with Graves’ disease (hyperthyroidism) aged nine years. This has led Anna to be interested in childhood Graves’, including the psychological issues. She also wants to promote knowledge of thyroid disease especially related to pregnancy.

Rachael Taylor

Rachael has spent the last decade working in education and along the way, she has launched learning centres in some of the most deprived areas in London. In her current role at Ivy House, she collaborates with a range of leading corporate organisations and schools across the UK. She can usually be found working outside her comfort zone - which probably explains why she enjoys running half-marathons in her spare time too!

At the age of 10, Rachael was diagnosed with hyperthyroidism, which led to a thyroidectomy a year later. After navigating the complexities of thyroid-related issues for most of her life, she is dedicated to championing and amplifying the voices of those living with thyroid disease.

Gavin Troughton

Gavin has spent over twenty years in commercial roles in the health technology space. He currently works as an advisor to breakthrough medical technology companies, helping with their product and commercial strategies.

Gavin says: Much of my work has involved engagement with healthcare systems, and I am a strong believer in supporting patients to understand and own their condition. I aim to use my business skills to support BTF to achieve its ambitions of supporting thyroid patients and championing research into improved treatments.

Nicola said: Our unit regularly uses the BTF information leaflets and we signpost patients to the website. Being a trustee provides the opportunity to become more formally involved with the BTF’s excellent work.  I believe my previous experience of working within a charity, and current role as a  trustee of the Edinburgh Royal Infirmary Diabetic Treatment Trust (ERIDTT), means I have the skills and commitment to support the BTF’s work.
