Dr. H.C. Yee (Helen M.C. Yee) is a Senior Staff Scientist at NASA Ames Research Center, where she has conducted pioneering research for over four decades. She earned her BS in Mathematics from the University of California, Davis and both her MS in Applied Mathematics and PhD in Nonlinear Dynamics from the University of California, Berkeley. Dr. Yee is internationally recognized for her contributions to computational physics, computational fluid dynamics (CFD), and nonlinear dynamical systems. Her work has focused on high-resolution shock-capturing methods, hypersonic flow simulations, and the development of advanced numerical techniques to improve the accuracy, predictability, and reliability of complex flow simulations. She is particularly known for integrating nonlinear dynamics with CFD to address numerical uncertainty and spurious solutions. With over 270 publications and more than 11,000 citations, Dr. Yee has received multiple honors, including NASA Space Act Awards and numerous technical achievement awards. She has delivered over 300 invited and keynote lectures worldwide and has served as an invited lecturer at the von Karman Institute for Fluid Dynamics. Her research continues to influence advancements in aerospace engineering, high-speed propulsion systems, and computational astrophysics.
