Biography

Dr. Peimeng Yin is an Assistant Professor in the Department of Mathematical Sciences at the University of Texas at El Paso (UTEP). He received his Ph.D. degree in the Department of Mathematics from Iowa State University in 2019 under the supervision of Prof. Hailiang Liu and Prof. Songting Luo. Prior to joining UTEP, he worked as a Postdoctoral Research Associate in Computer Science and Mathematics Division at Oak Ridge National Laboratory (ORNL), a Research Assistant Professor (research-track) in the Department of Radiation Oncology at the University of Kansas Medical Center, and a Post-Doc Fellow in the Department of Mathematics at Wayne State University.

He works in the area of Computational Mathematics and Applied Mathematics with the main focus on Numerical Analysis, Partial Differential Equations, Scientific Computing, and Data Science. His work reflects a strong interplay of rigorous mathematical analysis, the design and implementation of accurate and efficient numerical algorithms for partial differential equations (PDEs), and their applications to physics, astrophysics, engineering, biology, energy, and oncology. His research interests focus on advanced numerical methods for modern PDE challenges, such as high derivatives, maximum principle preserving, singularities, high dimensions and multiscale.
