Ahmed Ghazi is an associate professor of urology at the Johns Hopkins University School of Medicine. He is the Director of Surgical Simulation Training and the Division of Minimally Invasive and Robotic Surgery within the Johns Hopkins Brady Urological Institute.

Dr. Ghazi specializes in urologic surgical oncology using the latest techniques of minimally invasive surgery for prostate, kidney, bladder, ureteral and other genitourinary organ cancers. He also as specializes in minimal invasive treatment of complex stones of the urinary tract.

Dr. Ghazi is a pioneer in the field of patient-specific surgical simulation, which has applications for training future surgeons as well as improving outcomes for patients through individualized modeling. When planning for a complex surgery, Dr. Ghazi constructs 3D models of the patient’s anatomy in order to plan and rehearse surgery prior to the actual surgery. These models span from digital renderings to tangible models used to practice the critical components of your surgery.

Dr. Ghazi received his medical degree from Cairo University in Egypt in 2000, where he also completed his surgery training and urology residency. From there, Dr. Ghazi completed a laparoscopic fellowship in Paris, France in 2008, followed by a second laparoscopic fellowship in Austria in 2009. While practicing in Europe, Dr. Ghazi was accepted to the European Board of Urology. 

Dr. Ghazi continued his training at the University of Rochester, New York through a two-year fellowship in the robotic treatment of various urologic cancers. He then joined the staff at the urology department of University of Rochester in 2012 where he continued to practice until joining Johns Hopkins Medicine. 

Dr. Ghazi believes in a reciprocal relationship between innovation, surgery & research where each informs and strengthens the others. He strives to adopt innovative surgical technologies that are evidence-based, benefit his patients and translate directly to improved patient outcomes.

Research & Publications

Research Summary

My through understanding of learning theories, curriculum design and assessment methods has allowed me to help advance evidence-based surgical simulation research. I developed and validated a novel approach for fabricating high-fidelity, realistic, 3D physical models that offer a comprehensive simulated experience. I have expanded the application of extended reality technologies, remote proctoring, and machine learning in my laboratory. I strive to offer a patient-centered approach to surgical simulation, where trainees can master the specific maneuvers of individual operations, but also the entire gestalt of the operative experience with foreknowledge of anatomic details and surgical pitfalls for that specific patient.
