Professor Marian Ludgate

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.

Nancy Prest 

Nancy is a HR Professional and Founder of Doodle HR. Nancy says: Born as a surprise (mum and dad were just wanting one child but got a BOGOF offer with identical twins!) I have lived and grown up in Harrogate and never strayed (no pun) very far from home. I met my wonderful husband when I was 21 (some 20 plus years ago) and we were blessed with a beautiful son in 2011.

My thyroid cancer diagnosis in 2004 gave my husband and I a new outlook on life and once our son was born I decided to follow a dream and set up my own HR company in 2013. Doodle HR is a strange name for an HR company but I named it after the breed of a dog we owned. A beautiful labradoodle called Hunny.

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.
