Dr Randhawa received his M.D. degree from the All India Institute of Medical Sciences in 1983. He performed post-doctoral research at the University of Miami from 1984-1987 and followed it up by a residency in Pathology at the University of Pittsburgh, where he has spent the remainder of his academic career. He appointed as Assistant Professor of Pathology in July 1991, Associate Professor in January 1999, and Professor of Pathology with tenure in February 2007.  He is Director of the Transplantation Pathology Fellowship Program, and Past President of The Renal Pathology Society.

Dr Randhawa’s career can be best categorized as that of a clinical-investigator. He is an internationally known transplant pathologist who contributed to the development of The Banff Schema for Renal Allograft Pathology. His laboratory research has a strong focus on polyomavirus BK infection after transplantation. He published the first ever well documented case of BK virus nephritis diagnosed by needle biopsy. Following this initial discovery, he has made seminal contributions to the epidemiology, molecular biology, immunology and pharmacology of this virus, supported by multiple NIH grants totaling over 5 million dollars. He also has special interest in the application of Omics technologies to refine diagnostic renal transplant pathology.

His research is reported in the form of over 400 publications in Web of Science (sum of citations 17,240, average citations per item 39.1, and average citations per year 5561). He has served as a member of the education committee, abstract reviewer, session chair, and faculty presenter at several major conferences in transplantation. He is an associate editor for The American Journal of Kidney Diseases and Clinical Transplantation. He has served as a member of several NIH study sections and is a recipient of The American Society of Transplantation Established Investigator Award, Jacob Churg Award by The Renal Pathology Society, Ranbaxy Science Foundation Research Award for Medical Science, and The Distinguished Alumnus Award, Maulana Azad Medical College, University of Delhi.
