The Roberta Buffett Center for International and Comparative Studies will host Andrew Wachtel, president of American University of Central Asia, Tuesday at 12 p.m. in the Buffett Center Conference Room.

Wachtel, a former Buffett Center director and former dean of NU’s The Graduate School , will speak about “Central Asia Today and Tomorrow” with an emphasis on Kyrgyzstan.

Wachtel stepped down from his position at The Graduate School July 31 to take on his new job in Bishkek, Kyrgyzstan, according to an NU announcement. He was replaced by Dwight McBride, effective Nov. 1.

McBride was the dean of the College of Liberal Arts and Sciences at the University of Illinois at Chicago and previously chaired NU’s African American studies department.
