Dr. Anette Melk (MD PhD) is a Professor of Pediatrics and Transplantation Medicine at Hannover Medical School. She is the director of the DFG-funded Young Academy - PRACTIS (PRogram of hAnnover medical school for Clinician scienTISts).

Dr. Melk received her MD at the University of Giessen (Germany) and her PhD from University of Alberta (Canada). She trained as a Pediatric Nephrologist at the University of Heidelberg Children’s Hospital.

Dr. Melk’s translational work on pathways leading to impaired regeneration in the pathogenesis of renal and cardiovascular diseasesincludes basic findings and concepts from cell and animal models to clinical applications. She has pioneered the idea that cellular senescence is crucial for the insufficient regenerative capacity of donor organs and an important target in therapeutic approaches.

Dr. Melk’s clinical research projects aim to further decipher factors leading to cardiovascular and renal comorbidity in transplant recipients. She initiated the largest longitudinal clinical study assessing cardiovascular health in children and adults after solid organ and stem cell transplantation (4C-T, cardiovascular comorbidity in children with chronic disease and transplantation). Anette’s holistic view on optimization of patient and graft survival lead her build the first German research consortium that deals with sex- and gender-related differences in renal transplantation.

Dr. Melk serves on several national and international boards. She has received numerous awards, one of which is the prestigious Rudolf-Pichlmayr Prize of the German Transplant Society. She has published more than 100 scientific articles and book chapters; her current H-Index is 27.

I am a transplant surgeon at Manchester Royal Infirmary, part of Manchester University Hospitals NHS Foundation Trust, one of Europe’s busiest kidney and pancreas transplant programmes. I have been practising as a consultant surgeon in the NHS since 2011. I completed ASTS-accredited fellowships in abdominal multi-organ transplantation at the University of Minnesota and Wake Forest University in the United States.

My clinical work focuses on kidney and pancreas transplantation, including complex kidney transplantation and advancing safer and evolving approaches to pancreas transplantation. Within my institution I contribute to clinical leadership across several transplant-related services, including vascular access and infection prevention, areas closely linked to transplant outcomes and patient safety.

I have authored several peer-reviewed publications and book chapters in transplantation. During COVID-19 I developed the Singh Thattha technique, a culturally competent solution enabling faith-observant individuals with beards to safely wear respirator masks without shaving.

I actively engage with ethnic minority communities in the United Kingdom to promote deceased donor organ donation and help reduce disparities in transplant access. I maintain academic and professional collaborations across the United Kingdom, United States and India and serve as Professor at Sharda University, India, where I explore interdisciplinary research looking beyond traditional genetic paradigms in understanding disease and longevity.

I am the author of Journey Across Boundaries, reflecting on the human dimensions of transplantation, and produced the environmental awareness film Wheels of Civilization, which explores sustainability and humanity’s relationship with the natural world. I also engage with healthcare leadership on improving sustainability and reducing medical waste within healthcare systems.

I would be honoured to contribute to the work of TTS, working alongside colleagues globally to support collaboration, innovation, education and equitable access to transplantation while learning from the diverse experiences of our international community.

My 25-year career as a transplant nephrologist has focused on translational research addressing mechanisms of late kidney allograft failure, with particular emphasis on developing more effective and innovative immunosuppressive strategies. My work integrates laboratory investigation with clinical research to improve long-term transplant outcomes.

I am deeply engaged in advocacy for individuals living with kidney disease, having served as Chair of Public Policy for both the American Society of Transplantation and the American Society of Nephrology and receiving awards from the National Kidney Foundation and the American Association of Kidney Patients for career excellence in advocacy.

As Past President of the American Society of Transplantation, I strengthened partnerships with colleagues and organizations across the globe. My leadership within The Transplantation Society is reflected as Chair of Women in Transplantation, where I developed an industry-supported scientific grant portfolio to advance research on sex and gender in transplant access and outcomes.
