Plenary lectures

Be inspired by pioneers in (Bio)Artificial Organs and Organ Models

During ESAO 2025, each day will feature inspiring plenary lectures from leading experts who will share the latest insights and innovations in the field. These lectures offer participants the opportunity to be inspired by groundbreaking research, technological advancements, and the future of organ support and regenerative medicine. Each plenary speaker will provide new perspectives that will enrich the discussions and sessions throughout the conference. We look forward to learning and discovering together.

Stephen R. Ash, MD, FACP

CEO of HemoCleanse Technologies LLC

Dr. Ash recently retired from the Nephrology Department at Indiana University Health Arnett in Lafayette, Indiana. He is CEO of HemoCleanse Technologies,  Chairman of the Board of Ash Access Technology and co-founder of a number of spin-off biotechnology firms.  He has a long history of research and product development in the field of sorbents, resulting in devices for treatment of kidney failure (Allient™ by Renal Solutions) and for liver failure (Liver Dialysis™ by HemoTherapies). He was instrumental in development of an orally ingested sorbent for potassium (zirconium cyclo-silicate now marketed by AstraZeneca as Lokelma®). Dr. Ash has also invented a number of new catheters for dialysis access, including the Ash Split Cath®, CentrosFLO® and Channel™ peritoneal catheter.

Dr. Ash is a co-founder and Past President of the American Society for Diagnostic and Interventional Nephrology (ASDIN). He is Past President of ASAIO and until recently served as Secretary-Treasurer of IFAO. He is recipient of the Lifetime Achievement Award from ASDIN, the Celebration of Life Honor by NKF of Indiana,  the Lifetime Achievement Award from the Annual Dialysis Conference and recently the KidneyX prize from HHS and ASN for his work on uremic toxin sorbents.

Cristiano Amarelli, MD

Staff Surgeon at Monaldi
Azienda Ospedaliera dei Colli, Naples, Italy

Cristiano Amarelli graduated in 1998 as a medical doctor at the Second University of Naples. In 2003, he graduated as a cardiac surgeon. After finishing his residency in cardiac surgery, he completed his training focused on aortic valve surgery, aortic surgery, and Transplantation and MCS, which gradually became his main interest. Currently, he is a Staff Surgeon at the Monaldi Hospital, Azienda Ospedaliera dei Colli, and Adjunct Professor at the Vanvitelli Faculty of Medicine for the residency course in Cardiac Surgery on the Mechanical Circulatory Support. His areas of interest and publication are Myocardial Preservation, clinical implementation of LVADs in the local program, and donor allocation in Heart Transplant. During the last 10 years, he worked within the ESOT to develop a European network for Cardiothoracic transplant professionals (ECTTA), which is serving as chair and with the ASAIO becoming editor of the Journal and Board of Trustees. He is an active reviewer and editor for many Journals and Meetings in the field. He advocates the upcoming revolution of myocardial preservation and ex-situ organ perfusion as a potential game-changer for organ replacement therapies.
