Academic Biography
Thomas Yizhao Hou was born in 1962 and is an American mathematician. He pursued his undergraduate studies at the South China University of Technology, where he earned a Bachelor of Science degree in Mathematics in 1982. Hou’s passion for mathematics led him to pursue further education, and he completed his Ph.D. in Mathematics at the University of California, Los Angeles (UCLA) in 1987 under the guidance of Björn Engquist. His doctoral dissertation focused on the convergence of particle methods for Euler and Boltzmann equations with oscillatory solutions.
Following the completion of his Ph.D., Hou began his teaching career at the Courant Institute of Mathematical Sciences at New York University, where he served from 1989 to 1993. In 1993, he joined the faculty of the California Institute of Technology (Caltech) and has been a prominent member ever since. In recognition of his contributions, Hou was appointed as the Charles Lee Powell Professor of Applied and Computational Mathematics in 2004.
Research Contributions
Hou’s research has spanned various areas of applied mathematics, with a particular focus on numerical analysis and mathematical analysis. One of his notable areas of expertise is multiscale analysis and singularity formation of the three-dimensional incompressible Euler and Navier-Stokes equations. Hou and his former postdoc, Xiao-Hui Wu, developed the multiscale finite element method, which has been widely adopted in the engineering community. This method has found numerous applications, particularly in the field of flow simulation in major oil companies.
In 2014, Hou and Guo Luo presented compelling numerical evidence showing that the axisymmetric Euler equations develop finite-time singularities from smooth initial data. This breakthrough has significant implications for the understanding of fluid dynamics. Additionally, Hou’s research on the potentially singular behavior of the three-dimensional Navier-Stokes equations has generated considerable interest within the scientific community.
Hou has also made substantial contributions to computational fluid dynamics. His work on the convergence of the point vortex method for incompressible Euler equations was considered groundbreaking. Additionally, his development of the level set method for multiphase flows and the Small-Scale Decomposition method for fluid interface problems has had a significant impact on computational fluid dynamics, materials science, and biology.
Awards and Honors
Throughout his career, Thomas Y. Hou has received numerous prestigious awards and honors in recognition of his exceptional contributions to the field of mathematics. In 1990, he was selected as an Alfred P. Sloan Research Fellow. Seven years later, Hou was awarded the Feng Kang Prize in Scientific Computing. The American Physical Society honored him with the Francois Frenkiel Award in 1998.
Hou’s contributions to numerical analysis and scientific computing were acknowledged by the Society for Industrial and Applied Mathematics (SIAM), which awarded him the James H. Wilkinson Prize in Numerical Analysis and Scientific Computing in 2001. In 2005, the United States Association of Computational Mechanics (USACM) recognized his work with the Computational and Applied Sciences Award. More recently, in 2018, SIAM awarded him the Outstanding Paper Prize, and in 2023, he received the Ralph E. Kleinman Prize.
Hou’s induction into prestigious scholarly societies further demonstrates his impact on the field of mathematics. He was elected as a Fellow of the Society for Industrial and Applied Mathematics in 2009. In 2011, he became a Fellow of the American Academy of Arts and Sciences, and in 2012, he was elected as a Fellow of the American Mathematical Society.
