New Applied Math Faculty Members: Kui Ren and Hadrien Montanelli

The Applied Physics and Applied Mathematics Department is proud to announce the appointment of two new faculty members. APAM alumn, Kui Ren, joins us as a Professor of Applied Mathematics, and Hadrien Montanelli is a Chu Assistant Professor of Applied Mathematics.

Kui Ren is a new Professor of Applied Mathematics. Prof. Ren received his B.S. from Nanjing University in China and obtained his Ph.D. from the Applied Mathematics program in the APAM Department at Columbia University in May 2006. Following his Ph.D., he moved to the University of Chicago in 2007 where he worked as the L. E. Dickson instructor. In Fall, 2008, Ren joined the University of Texas at Austin as an assistant professor in the Department of Mathematics and the Institute for Computational Sciences, Engineering and Mathematics (ICES) and was promoted to Associate Professor in 2014.

Prof. Ren's research involves several aspects of applied and computational mathematics. His recent work include theoretical and numerical analysis of inverse problems related to partial differential equations with applications in biomedical imaging, mathematical modeling and computation of the propagation of high frequency acoustic/electromagnetic waves in random media, numerical and mathematical studies of random graphs and networks, as well as numerical algorithms for kinetic modeling of electrostatics and charge transport in semiconductor devices.

Hadrien Montanelli is a new Chu Assistant Professor of Applied Mathematics. Before joining Columbia, he received his Ph.D. in Applied Mathematics in 2017 from the University of Oxford where he studied numerical algorithms for PDEs with Nick Trefethen. His general research interests lie in nonlinear and nonlocal PDEs, approximation theory and deep learning.

The two year, non-tenure track Chu Assistant Professor position was named after C.K. "John" Chu, the Fu Foundation Professor Emeritus of Applied Mathematics and former chair of the APAM Department.
