John P. Kostuik, M.D., Spine Research Fellowship

The John P. Kostuik, M.D., Spine Research Fellowship is designed for motivated 3rd or 4th-year medical students interested in gaining orthopaedic surgery research experience through an immersive program at one of the top academic medical centers.

Prior to establishing the John P. Kostuik, M.D. Spine Research Fellowship, the Department had a history of mentoring medical student research fellows for more than a decade under Dr. Kebaish’s leadership. Former fellows include those who continued to orthopaedic residency at Johns Hopkins Medicine and are now in private or academic practice in spine surgery.

"During the interview process, I was struck by the commitment to mentorship that Dr. Kal Kebaish, Director of the Spine Division, and his network of former mentees demonstrated. This fellowship goes far beyond providing opportunities to learn and explore world-class research in spine orthopedics. I am looking forward to improving my research abilities, developing my relationships with mentors and colleagues, and deepening my understanding of spine surgery. I am so grateful to have this opportunity to spend a year with the amazing people here at Johns Hopkins Medicine.”

From the Orthopaedic Surgery Department Chair, James Ficke, M.D.: "I have spent some time with Kevin talking about research and his time here so far, and I am impressed with his drive to learn about the orthopaedic surgery profession and his interest in using this year with us to absorb as much as he can. He is immersing himself with activities in the department and came well prepared to our Journal Club. I believe Kevin is a perfect person to serve as our inaugural Kostuik Fellow.”
