The National Council of Teachers of Mathematics has named Kichoon Yang, the provost at Northwest Missouri State University, as its new executive director.
Yang, who replaces outgoing executive director Jim Rubillo, will take over the post on July 1. Rubillo had announced his intent to retire last year from that position at NCTM, an influential, 100,000-member organization based in Reston, Va.
Before working at Northwest Missouri State, Yang was dean of the College of Natural Sciences and professor of mathematics at the University of Northern Iowa from 2001 through 2004, according to NCTM. He also was a program director in the Division of Mathematical Sciences at the National Science Foundation for three years. Earlier in his career, he served for 12 years on the mathematics faculty at Arkansas State University. He received a B.S. in math from the University of North Carolina and a Ph.D. in math from Washington University in St. Louis.
