Professor of Surgery

University of Maryland

I have been involved continuously in basic cellular and molecular transplant immunology for 30 years. My basic research has always focused on T cell immunobiology, and for more than 20 years has also focused on issues of migration, trafficking, secondary lymphoid organ structure and function, and lymphatic structure and function, and how these processes and structures influence T cell immunity and T cell tolerance in models of transplantation. I have also maintained an active clinical practice in solid organ transplantation and am thus constantly exposed to the problems of patients and their immune systems, including cellular and humoral rejection, opportunistic infections, chronic viral disease, autoimmune organ failure, and immunosuppression medication side effects. I have had over 60 trainees in my lab, am actively involved in teaching and mentoring, and have served on T32 faculty.

His achievements include several NIH and non-NIH grants during his academic career. He is a member of the executive committee of COTS and a member of the advisory council of TRM of the AST. Dr. Mohiuddin's career has been a testament to his pioneering spirit in Xenotransplantation. His groundbreaking contributions include demonstrating the most prolonged survival in heterotopic and orthotopic cardiac Xenotransplantation. He devised an immunosuppression regimen that significantly extended the lifespan of cardiac xenografts to nearly three years. His leadership extends to IXA, where he now serves as President, following four years as Councilor and a liaison to foster productive dialogue between the IXA and the FDA. His extensive publication record includes over 120 papers and more than 150 abstracts, and he has been a sought-after expert speaker on Xenotransplantation on numerous occasions.

Dr. Mohiuddin's unwavering dedication to Xenotransplantation culminated in two significant milestones. On January 7, 2022, he achieved the First Genetically Engineered pig-to-human cardiac Xenotransplantation, a feat that marked a new era in the field. He then led the second xenotransplantation procedure in September 2023, further solidifying his position as a leader in the field. Both surgeries were successfully conducted at the University of Maryland Medical Center in Baltimore, Maryland. Besides other awards, Dr Mohiuddin was picked by Nature Journal as one of the “Nature’s 10” in 2022. Ten people who helped shape science in 2022.

Dr. Wayne Hawthorne is the Immediate Past President of IXA, the current of ACBMS, Chairman of the Xenotransplantation Working Group of TSANZ and Chairman of WSLHD AEC. Professor Hawthorne’s career has focused on treatments for Type 1 Diabetes (T1D), having established the laboratory and techniques to perform islet cell isolation for Australia's First Clinical Islet Transplant program. Paralleling the clinical program Professor Hawthorne has dedicated his research career to establishing Australia’s Islet Cell and Xenotransplantation research programs, obtaining ongoing NH&MRC and Breakthrough T1D grants for more than 25 years. He developed and has established the Westmead NHP facility and has extensive small and large animal surgical and anaesthetic expertise that few others have in Australia. He has decades of expertise in large animal models, including the use of NHP’s in research. He continues to oversee the islet and xenotransplant research programs at the Westmead facility and remains dedicated to continuing to develop and provide the most Ethical and humane ways to run medical research projects and ensure their translation to the clinic along with the training of many scientists, clinicians and surgeons.

A founding researcher of the Centre for Transplant and Renal Research at the Westmead Institute for Medical Research and The University of Sydney, he remains responsible for surgical research projects where he has supervised many students including; PhD, Masters, Hons and MD students. He continues to build on the success of his research work and his team have translated the transplantation treatments for T1D, being the first in Australia to perform both Clinical Allo and Auto islet cell isolation and transplantation and to perform islet after kidney and combined islet/kidney transplants into clinical patients. He has performed more than 330 clinical islet isolations and islet cell transplants in both adults and children as young as 4 years of age. He has >250 journal publications, 20 books and book chapters and >700 published proceedings along with presenting numerous International and National presentrations.

Associate Professor of Surgery
University of Maryland, Baltimore, MD, USA

Raphael P. H. Meier, M.D., Ph.D. is a liver, kidney, and pancreas transplant and hepatobiliary surgeon and Associate Professor of Surgery at the University of Maryland School of Medicine. Dr. Meier completed his medical education at the University of Geneva School of Medicine in Switzerland, followed by a general surgery residency at the University of Geneva Hospital. He further honed his expertise through a fellowship in abdominal transplant surgery at the University of California, San Francisco (UCSF).

His research spans both basic science and clinical aspects of abdominal organ transplantation. Dr. Meier has made significant contributions to the field, developing microencapsulated and genetically modified mesenchymal stem cells to deliver anti-inflammatory cytokines for treating chronic liver diseases. His work also explores the genetic factors influencing islets of Langerhans function and their impact on diabetes and islet transplantation outcomes. Currently, Dr. Meier is part of a conducting effort to develop suitable xenogeneic organs, addressing the critical worldwide organ shortage.

A prolific researcher, Dr. Meier has authored over 100 scientific manuscripts and book chapters, published in prestigious journals including JAMA Medicine, Journal of Hepatology, American Journal of Transplantation, and Transplantation.

Dr. Meier is actively involved in several international organizations. He serves as a councilor of the International Xenotransplantation Association and is a committee member of the Basic and Translational Research Committee for the International Liver Transplantation Society. Additionally, he is a member of the American Society of Transplant Surgeons and the American Society of Transplantation, further demonstrating his commitment to advancing the field of transplantation medicine.
