Kevin Chang, a first-year student in the Texas Academy of Mathematics and Science at UNT, and two teammates received fifth place in the national 2011 Siemens Competition for their work on graph theory.

The Siemens Competition is the nation's leading original research competition in math, science and technology for high school students. The national finals were held at George Washington University in Washington, D.C., in December 2011. Chang and his teammates will split the $20,000 award for their efforts along with $6,000 they won at the regional competition.

The TAMS program had more Siemens regional semifinalists and regional finalists than any other school in the nation this year.

Chang and his teammates Andrew Xu of San Francisco, Calif., and Kevin Tian of Austin, Texas, met at a summer math camp. Their project titled Determining the Existence of Graceful Valuations of Various Families of Graphs developed algorithms that will help optimize social and communications networks by labeling graph vertices and axes. Chang and Tian were the only two winners from Texas this year.

TAMS is a unique, two-year residential program at UNT for high school-aged Texas students who are gifted in math and science.

TAMS has had more than 80 students named semifinalists, regional finalists or finalists since 2002. In 2008, TAMS student Wen Chyan won the national contest and the $100,000 that accompanies it.
