In the quest for higher education, even popstars know the importance of achieving a college degree!

Most of them, before they were famous, enrolled in some of the top universities across the country in order to exercise their brains in the same way they workout their vocal chords.

Greg wowed us with his incredible DJ skills at Lollapalooza, but it wasn’t until we realized he used to be a biomedical engineer and graduated from Case Western Reserve University in Cleveland, Ohio that we realized just how talented he was outside of music.
