Lab members Omar and Khalid Saffaf – both pre-med students at the University of Missouri-St. Louis – earned spots as pre-med students at the Introduction to Academic Vascular Surgery Conference in April 2017 in Tampa, Florida. The conference accepts only 15 med and pre-med students combined.

This article in the UMSL Daily newspaper describes how the Khalid and his sister Alaa went to St. Louis Children’s Hospital to support brother Omar through a dozen or so operations – leading all to become pre-med students.
