Dr Mengel is Interim Chair of the Department for Laboratory Medicine and Pathology at the University of Alberta, Edmonton, Canada. He is also Section Head for Transplantation Pathology at the Division of Anatomical Pathology. Outside his faculty Dr. Mengel is engaged in various international sub-specialty societies related to nephropathology and organ transplantation. He is the past Chair of the Transplant Diagnostics Community of Practice in the American Society of Transplantation, and a member of the Organizing Committee of the International Banff Conference for Allograft Pathology. He was Chair of the Program and of the Transplant Committee with the International Renal Pathology Society.

He studied medicine at the Semmelweiss University in Budapest, Hungary before going on to specialise in pathology and further in transplantation pathology and nephropathology. Before moving to Edmonton he was head of the transplant pathology service at the Hannover Medical School, Germany with responsibility for diagnostics and research based on transplant biopsies. In Edmonton, Dr. Mengel’s current work is focused on applying modern molecular and biostatistical techniques to biopsy specimens, with the aim to increase diagnostic precision in the area of organ transplanation.
