Dr. Allaf is an Assistant Professor of Urology and Biomedical Engineering at the Brady Urological Institute and Director of Minimally Invasive and Robotic Surgery at the Johns Hopkins Hospital. He joined the staff after receiving his undergraduate and medical degrees from the Johns Hopkins University and completing his residency and advanced training in Urology at Johns Hopkins as well.

His main clinical interest includes the treatment of kidney tumors and prostate cancer in the least morbid way possible. He specializes in the management of kidney tumors via laparoscopic (total and partial kidney removal) and percutaneous (non-surgical) approaches. He also has an interest in the careful and active observation of select small kidney tumors. His other areas of focus include performing nerve sparing radical prostatectomy in all its forms (open, laparoscopic, and robotic) as well as reconstructive laparoscopy (pyeloplasty) and laparoscopic management of testicular cancer (retroperitoneal lymph node dissection).

His research endeavors involve investigating approaches to minimize the morbidity of urologic surgery and the development of ways to decrease injury to the neurovascular bundles and hasten erection recovery following radical prostatectomy. Dr. Allaf has been the recipient of numerous academic awards, including placing first in the 2005 American Urological Association clinical and laboratory research annual essay contests. He has written and published numerous research articles, textbook chapters, patents and video presentations in the field of Laparoscopic and Robotic Urologic Surgery.
