Neurosurgery Residents and Fellows

Karim ReFaey M.D.

Karim earned his medical degree from Ain Shans University in Cairo, Egypt in February 2014, and shortly thereafter joined Dr. Quinones’ team as a visiting student for three months. In August 2014, Karim returned to the team and began working as a post-doctoral fellow where he now investigates the ways in which mesenchymal fat cells are able to fight brain tumors when they are packaged with anti-cancerous drugs and delivered to brain tumor cells as a “Trojan horse.”

Currently Karim is working on several chapters and neurosurgical videos for Dr. Q’s prospective edition of Schmidek and Sweet, and in his free time serves a member of the Health Egyptians Organization, an NGO that combats the lack of health education in Egypt. Karim also enjoys swimming and has competed professionally at both the national and international level, earning himself titles in both spheres.

Tito Vivas Buitrago M.D.

Tito first joined Dr. Quiñones' team in May of 2014 as a medical student finishing his last sub-internship rotation for a period of 6 months. He also did part of his sub-internship at The Naval Force Hospital in Cartagena and The Comuneros Hospital in Bucaramanga. Tito received his medical degree from the University of Santander in Bucaramanga, Colombia in 2014.

He is currently working with the team as a post-doctoral fellow helping elucidate the behavior of remanent GBM cells after surgical resection in the recurrence of brain lesions. Tito is also assisting in the development of the upcoming neurosurgical textbook, Comprehensive Multimedia Video Atlas of Skull Base Surgery and Tumors. He is also involved in various research projects as part of Dr. Quiñones’ team.

Tito is funded by the Universidad de Santander, Colombia and the Neurotrauma Center I.P.S.
