Work Experience

2023 Nov- Assistant
Professor 		TU Eindhoven, The Netherlands
CASA: Centre for Analysis, Scientific Computing and Applications, Mathematics and Computer Science Department
As a part of the Computational Illumination Optics group, I currently focus on inverse optical design.
  • The problem is to design an optical system that transports light energy distribution f at source to g at target
  • Fundamentally it is an optimal transport problem, but much much harder (as is real life 😉)

2022-2023 Independent
Researcher 		Hasselt University, Belgium
Project: AdaPore: rigorous and fully adaptive model selection for multiphase flow through porous media.
Developed guaranteed, robust and efficient a-posteriori estimators for general nonlinear elliptic problems (click here for the FreeFem codes). Used the results for a rigorous and adaptive linearization algorithm for the Richards equation.
2021-2022 Post-Doc Radboud University, The Netherlands Advisor: Dr. S. Sonner
I investigated the PDE-PDE & PDE-ODE models arising from spread of biofilms. Biofilm equations are nonlinear degenate parabolic equations couple to a substrate equation by the source term. We looked into the existence-uniqueness of weak solutions, as well as, travelling wave solutions, their stability, and in general spreading behaviour of the biofilms.
2020-2021 Post-Doc INRIA Paris, France Advisor: Prof. M. Vohralik
Project: ERC Consolidator Gatipor: We derived robust and locally space-time efficient a-posteriori error bounds for fully degenerate Richards equation, and demonstrated the efficiency of the estimators numerically. The FreeFem+ codes can be found in this github repository .
2019-2020 Post-Doc TU Dortmund, Germany Advisor: Prof. B. Schweizer
Formulating as a one and higher dimensional TW problem, we proved the existence of finger solutions having a free-boundary. The predictions were validated numerically by an adaptive algorithm.
