William Waller

Professor & Associate Dean

Office: S655

​I transferred from Eastfield Community College in Dallas to the University of North Texas in 1979, where I majored in mathematics. I completed my Master's degree in Mathematics at North Texas in 1983. I moved to Houston on the same day I took my last final exam at North Texas, in order to teach freshman mathematics and computer science at UHD. While serving as a lecturer at UHD, I also pursued my Ph.D. in mathematics at UH under the supervision of Siemion Fajtlowicz. I am the first person to write a dissertation proving a computer-generated conjecture. Upon finishing my degree in 1989, I was promoted to Assistant Professor, eventually becoming full professor in 2010. I have maintained a strong interest in teaching freshmen, serving as Director of UHD's first Quality Enhancement Plan. I became Associate Dean for the First-Year Experience in UHD's University College in 2012.

​My mathematical research focuses on extremal graph theory involving classical graph invariants and automatic conjecture generation. My pedagogical research focuses on improving student success in freshman and sophomore barrier courses, particularly those in mathematics.
