My research focuses on developing and analyzing efficient numerical methods for problems arising in science and engineering. 

My research interests span traditional numerical methods and machine learning and data science. Some of the topics I investigate include neural networks for multiscale and singularly perturbed problems, nonlinear approximations by neural networks and radial basis functions for PDEs, error estimates of neural networks for conditionally stable PDEs, unfitted finite element methods for interface problems, and numerical methods for nonlocal PDEs. 

At WPI, I mainly work with Prof. Zhongqiang Zhang and Prof. Marcus Sarkis.
