Cynthia Y. Young is a Pegasus Professor of Mathematics and the Vice Provost for Faculty Excellence and International Affairs and Global Strategies at the University of Central Florida (UCF) and the author of College AlgebraTrigonometryAlgebra and Trigonometry, and Precalculus. She holds a bachelor’s degree in secondary mathematics education from the University of North Carolina (Chapel Hill), a master’s degree in mathematical sciences from UCF, and both a master’s degree in electrical engineering and a PhD in applied mathematics from the University of Washington. She has taught high school in North Carolina and Florida, developmental mathematics at Shoreline Community College in Washington, and undergraduate and graduate students at UCF.

Young joined the faculty at UCF in 1997 as an assistant professor of mathematics, and her primary research area was the mathematical modeling of the atmospheric effects on propagating laser beams. Her atmospheric propagation research was recognized by the Office of Naval Research Young Investigator Award, and in 2017 she was selected as a fellow of the International Society for Optical Engineering. Her secondary area of research centers on improvement of student learning in mathematics. She has authored or co-authored over 60 books and articles and has served as the principal investigator or co-principal investigator on projects with more than $2.5 million in federal funding.

Young was on the team at UCF that developed the UCF EXCEL program, which was originally funded by the National Science Foundation to support the increase in the number of students graduating with a degree in science, technology, engineering, and mathematics (STEM). The EXCEL learning community approach centered around core mathematics courses has resulted in a significant increase in STEM graduation rates and has been institutionalized at UCF.

Young has been the recipient of many of UCF’s awards (Excellence in Undergraduate Teaching, Excellence in Research, Teaching Incentive Program, Research Incentive Program, Scholarship of Teaching and Learning award as well as UCF’s highest honor, UCF Pegasus Professor). She has shared her techniques and experiences with colleagues around the country through talks at colleges, universities, and conferences.
