Dr. Diana White received her Ph.D. in 2007 from the University of Nebraska under the direction of Sean Sather-Wagstaff. She then held a research postdoctoral position at the University of South Carolina. Her research focus centered on homological aspects of commutative algebra, specifically relative homological algebra with respect to semidualizing modules.

Upon coming to the University of Colorado Denver in 2008, Dr. White became a mathematician in mathematics education. She specifically focuses on the mathematical development of pre-service and in-service teachers at all levels.

She is the P.I. on the National Science Foundation Rocky Mountain Noyce Scholars Program grant. This interdisciplinary grant with the School of Education and Human Development provides scholarship and internship opportunities to undergraduate pre-service secondary math teachers at the University of Colorado Denver. As part of this grant, she led the redesign of the secondary math education option of the mathematics major at UCD to align with the Conference Board of the Mathematical Science recommendations on the Mathematical Education of Teachers. She is actively working with the School of Education and Human Development to integrate the content and methods aspects of teacher training.

Dr. White is also the project director for the Rocky Mountain Math Teachers' Circle, a professional development program for middle-level math teachers that focuses on mathematical problem solving. At the national level, she is on the advisory group for the Special Interest Group on Math Circles of the Mathematical Association of America, and she is actively researching the impact of Math Teachers’ Circles on participating teachers at both the local and national levels.
