George Ciccariello-Maher, a professor of politics and global studies, had been teaching his class remotely via video conference after being put on administrative leave, a move that Drexel said was for his own safety.
The professor said his resignation is effective December 31.
"This is not a decision I take lightly; however, after nearly a year of harassment by right-wing, white supremacist media outlets and Internet mobs, after death threats and threats of violence directed against me and my family, my situation has become unsustainable," Ciccariello-Maher wrote on his Facebook account. "Staying at Drexel in the eye of this storm has become detrimental to my own writing, speaking, and organizing."
