Assistant professor of Finance at Simon School and still in teens?

From the Australian:

"TWO Russian-born sisters are due to become assistant professors of finance in New York later this year, at the tender ages of 19 and 21, university officials said.Angela Kniazeva and her younger sister Diana were due to take up their new positions in September at the University of Rochester, where half of their students will likely be older than them.

The pair, who already have masters degrees in international policy from Stanford University in California, will pick up their doctorates from New York University's Stern business school after five years of study."

Gee, I feel old now.
