Umberto Tosi received his medical degree with Honors in Research from Weill Cornell Medical College in 2020. As a medical student, Dr. Tosi worked in the laboratory of Dr. Mark Souweidane of the Children's Brain Tumor Project, investigating novel drug delivery technologies in treating pediatric gliomas. During his tenure as a medical student he was awarded an Alex's Lemonade Stand Foundation POST Grant and the Rudin Pediatric Neuro-oncology Fellowship; upon graduation he won the Harold G. Wolff Research Prize for his work.

Dr. Tosi grew up in Italy, then earned his bachelor’s degree summa cum laude from the University of Pennsylvania, double majoring in Biological Basis of Behavior and Chemistry. He was inducted in Phi Beta Kappa in 2015. He completed his Honors Thesis under the supervision of Dr. Jeannie Chin at Jefferson University, investigating the role of early epileptiform activity in the development of epigenetic dysregulation in Alzheimer’s Disease models. In addition to publishing his research with numerous members of the department, Dr. Tosi has mentored medical students in a variety of subjects.

Rafael Uribe, MD, MHS

PGY-5 Resident

Full Bio

Dr. Uribe completed his neurosurgical residency in 2014 in his native Colombia, then earned a Master of Health Science at the Bloomberg School of Public Health at Johns Hopkins University in 2015.
