PVRI Structure & Governance

Council of the PVRI/Board of Trustees

Karen Osborn, Chief Executive

Karen is an experienced charity CEO and loves the innovation, flexibility and responsiveness of the sector. Her most recent roles have been in the sight loss sector, and she joins us from Glaucoma UK, where she spent 6 years leading a period of successful growth.

Anna Hemnes, PVRI President 2024 - 2026 & Trustee

Anna Hemnes, MD, is a translational physician-scientist with a research focus on the role of altered metabolism in pulmonary vascular disease. Her basic research is on the effect of BMPR2 mutation on insulin-mediated intracellular signaling in the pulmonary vasculature and the right ventricle. Dr Hemnes's clinical research interests include the role of insulin resistance and metabolic syndrome in human pulmonary vascular disease with a focus on genetic susceptibility to these conditions, and deep molecular phenotyping of pulmonary vascular disease.

This interest in molecular phenotypes of pulmonary vascular disease has led to her prior work demonstrating an Omic signature of vasodilator-responsive pulmonary arterial hypertension, one of the earliest publications demonstrating the feasibility of precision medicine in an ultra rare pulmonary vascular disease. Dr Hemnes's lab is now actively investigating novel blood-based Omic predictive strategies for FDA-approved therapies for pulmonary arterial hypertension.

She actively sees patients in the Vanderbilt Center for Pulmonary Vascular Disease and has effectively worked with this population to recruit into clinical studies for pulmonary vascular disease, including the treatment of pulmonary hypertension, diagnostic modalities in pulmonary vascular disease and novel classification of pulmonary vascular disease. Dr Hemnes's lab has a unique and powerful capacity to study molecular mechanisms of pulmonary vascular disease and right heart dysfunction in studies spanning cell culture and rodent models through human translational studies and clinical trials.

Paul Corris, Chair of the Board & Trustee

Paul Corris is Emeritus Professor of Thoracic Medicine and faculty member of the Institute of Cellular Medicine at Newcastle University.

He holds an honorary consultant physician contract at The Newcastle Hospitals NHS Foundation Trust (Newcastle Upon Tyne, UK) and directed the National Pulmonary Vascular Service (NPVS) in Newcastle, being one of a small group who set up the UK National Service in 2001.

He played a major international role in establishing lung transplantation as a viable clinical entity and directed the NPVS from 2012 to 2017. Paul is also a Past-President of both the British Thoracic Society and the International Society for Heart and Lung Transplantation.

He was President of the Pulmonary Vascular Research Institute for and also held the position of PVRI Chief Medical Scientific Officer for the 2018/19 term, as well currently acting as the Chair of the PVRI Interim Board of Directors.

Sir Graham Wylie, Stepped down in February 2024

Sir Graham was one of the original founders of The Sage Group Plc (“Sage”) progamming the original Sage Accounting software whilst still at Newcastle University studying for a joint honours degree in Computer Science and Statistics in 1981. After leaving University in 1989 Graham along with three other colleagues floated the business on the London Stock Exchange. Following flotation Graham became Managing Director of Sage (UK) and a Group Director of The Sage Group Plc. Under Graham’s leadership, Sage (UK) became a market leader in the accounts and payroll software market with almost 1 in 3 of all VAT registered UK businesses using a Sage product by 2003. Graham “retired” from Sage in 2003 and at the time The Sage Group Plc employed 6,000 people, had 3,000,000 customers and was a huge financial success with revenues of £560m, profits of £151m and a market capitalisation of £2.5b. 

In 2004 Graham purchased the Close House estate from Newcastle University and has since developed into one of the top 100 golf resorts in the UK & Ireland.  Close House has the only PGA Academy in the North of England and hosted the PGA Seniors championship and the EuroPro tour in 2015. Close House then successfully hosted the European Tour’s British Masters in 2017 and 2020 attracting a host of famous players to the North East. 

In 2012, Graham embarked on a brand-new venture called Speedflex. This is an exercise machine and concept that helps improve the cardiovascular system and fitness and can be used by everyone. The intention is to create Speedflex centres throughout the UK but, in time, also Worldwide as Graham holds the exclusive licence for all these territories.  

In 2015 Graham successfully chaired the local organising committee for the British Transplant Games. Due to their success Graham was asked to bid for the World Transplant Games and subsequently was awarded the games which were held in Newcastle/Gateshead in August 2019 and again Graham was Chairman of the Organising Committee. The games were a huge success and helped spread the important message of signing up to be an Organ Donor and saving many lives.   

Graham is married with four children and three grandchildren. In 2009 his wife Andrea gave birth to twins but one of them had a serious heart defect. Kiera has had open heart surgery three times in the space of her first two years and Graham is indebted to the Children’s Heart Unit at the Freeman hospital for saving his daughter’s life. He is now a patron of CHUF, the charity to raise money for the hospital, and has raised several millions of pounds over the recent years to help fund the building of an accommodation facility for parents of children going through surgery as well as updating much of the equipment used by the children’s heart unit. 

In 2015 Graham decided to start his own charitable foundation, the Graham Wylie Foundation, set up to Help, Educate and Inspire the Children and young people in the North East. The Foundation funds local projects the most recent being a Music Therapy Centre in Newcastle, which was opened in the Spring of 2018 by Sting. This centre is the first of its kind outside of London.


  • Contribution to the North East region has been acknowledged by the awards of honorary doctorates at both Newcastle and Northumbria University 
  • Honoured by the Queen with a CBE.
  • Received a Knighthood in the 2020 New Year’s Honours list.

Stuart Rich, (Founder & Former Trustee)

Dr Stuart Rich MD is a cardiologist and Director of Pulmonary Vascular Disease Programme at the Bluhm Cardiovascular Institute and a Professor at Northwestern University’s Feinberg School of Medicine.

He is one of the world’s most recognised experts on pulmonary vascular diseases. For more than three decades he has dedicated his research and clinical efforts to finding better solutions for pulmonary hypertension. Dr Rich completed his residency training in medicine at Washington University in St Louis, and fellowship in cardiology at the University of Chicago.

His career began at the University of Illinois, where he was the principal investigator for the National Institutes of Health’s (NIH) Registry on Primary Pulmonary Hypertension, the first of its kind, and has been the leader of the largest clinical centre in the US for evaluating and treating patients with pulmonary hypertension since 1980.

Dr Rich has conducted cutting-edge research on the molecular mechanisms and epidemiology; clinical presentation, natural history, and has been at the forefront of the development of virtually every new form of pulmonary hypertension treatment. His pioneering research has led to a greater understanding of all types/stages of pulmonary hypertension, as well as the use of new therapeutic procedures and devices.
