Alia Sabur, a 19-year, an American, has been declared the world's youngest professor in history by the Guinness Book of World Records. Alia broke the 1717 record set by a student of physicist Isaac Newton, Colin Maclaurin.

She went from 4th grade to college, earning a BS in Applied Mathematics summa cum laude from Stony Brook University, New York at age 14, the youngest female in American history. She then earned an MS and PhD in Materials Science and Engineering from Drexel University, Philadelphia.

Alia is the youngest ever to receive fellowships and awards from the US Department of Defence, Nasa and the US National Science Foundation.

"I really enjoy teaching," said Sabur. "It’s something where you can make a difference. It's not just what you can do, but you can enable a lot of other people to make their changes."
