Dr Kate Lynch

Kate Lynch
Dr Kate Lynch has spoken at various international meetings on her research as well as on PSC, and published over 20 manuscripts, review articles and book chapters in international peer-reviewed journals and textbooks. She is passionate about helping patients with PSC, in helping to manage their condition and teach them about their disease, as well as pursuing research which will improve outcomes for patients living with PSC. She is involved in patient and public education on the condition, speaking at various patient support group meetings as well as being an expert medical advisor to PSC Support UK and PSC Support Australia. She has recently returned to Adelaide, Australia, after 7 years at Oxford under the tutelage of Dr Roger Chapman and Prof Satish Keshav, and she aims to continue her research in this area in Australia.

Dr Kate Lynch (née Williamson) is a gastroenterologist and hepatologist practising in Adelaide, South Australia. Her interests lie in autoimmune liver diseases, such as PSC, PBC and autoimmune hepatitis, as well as inflammatory bowel disease. She has just recently completed her DPhil in Clinical Medicine at University of Oxford, entitled "Peripheral blood, Liver and Intestine-specific lymphocytes in Primary Sclerosing Cholangitis and Inflammatory Bowel Disease".

Her current research involves analysis (via flow cytometry, immunohistochemistry and single cell RNA sequencing) of immune cells derived from the peripheral blood, gut, and liver in patients with PSC/IBD and controls. In particular, she harnesses a minimally invasive technique, fine needle aspiration of the liver, to access immune cells directly from the PSC liver. The aim of her research is to understand further the gut-liver axis role in the pathophysiology of PSC/IBD. In addition to laboratory-based research, Kate is involved in clinical trials of novel agents in both PSC and IBD.

Lay Members

Maxine Tapp (née Cowlin)

Maxine at EURORDIS training

Maxine at EURORDIS Summer School training

Maxine was diagnosed with PSC in 2006 at the age of 17. After 7 years of her PSC staying fairly under control, studying dance at university, working and travelling, Maxine’s condition progressed unexpectedly and significantly. She was listed for transplant in 2013 and spent 15 months on the transplant waiting list until she received her new liver.

In December 2018, Maxine was appointed as Programme Development Officer for PSC Support, becoming the charity’s first ever employee.

'PSC Support has helped me enormously since my diagnosis in 2006. Without the charity and its commitment to supporting patients and providing up to date, quality information, my experience with PSC would have been even more challenging. I am extremely passionate about fulfilling the objectives of PSC Support and am dedicated to ensuring the charity continues to move forwards and help even more people.’

Having experienced the condition from diagnosis through transplant, I wanted to share my experience of PSC with other patients to provide a level of transparency and reality; particularly in the younger age group and those with children.

The work that Martine and the wider PSC Support team continuously undertake has been invaluable in helping to improve the lives of people with primary sclerosing cholangitis (PSC) through support, education, advocacy and research.'

Gary is also a Trustee of PSC Support.

Martine Walmsley

Martine WalmsleyMartine, PSC Support Trustee, was diagnosed with PSC in 2007, and has volunteered for PSC Support since then, becoming Chair of Trustees in 2011. She is driven and committed to doing everything in her power to help progress PSC research towards effective treatment, and making those treatments accessible to all PSC patients.

Recognising that there was a gap between the way medical professionals saw PSC and the way PSC patients saw (and lived with) PSC, she drew together and evidenced patient perspectives through PSC Support to help drive improvements in care and to influence PSC research direction. This was the impetus for the PSC Quality of Life Measure, which is under development in the UK.
