Because of her fascination with the idea of gathering economic data through statistical sampling and modeling human behavior through mathematical economics, she studied game theory and statistics at the Harvard Summer School. Nguyen got the idea of studying Ehrenfeucht games from mathematician Joel Spencer of New York University, but she did the analysis entirely on her own. Ehrenfeucht himself now focuses his attention on mathematical biology and mathematics education. He and Pat Baggett of New Mexico State University have developed math and technology courses for elementary school teachers. They also invented a strategy game called Tic Tac Twice, which is now available commercially.
