Student Projects and Theses

If interested please contact the lecturer offering the project.
Note: Most projects are suitable for both students of mathematics and computational science and engineering.
Our research group focuses on the study of stability and regularization of ill-posed problems which arise in various applications. For such problems conventional solvers yield unreliable outputs, so that regularization techniques are necessary to produce trustworthy solutions. Research topics include medical imaging, phase retrieval (with application in coherent diffraction imaging and audio processing) and the vulnerability of deep neural networks. Theses projects on these topics are available, with possible emphasis on either implementation or analysis.
Our goal is to develop new mathematical models and methods of broad utility to science and engineering and to make fundamental advances in the mathematical and physical sciences themselves. We have been developing mathematical and computational frameworks to achieve super-resolution in biomedical imaging. Our work on biomimetics focuses on elucidating mechanisms exploited by bats and weakly electric fish for imaging. Nanophotonics is the study of electromagnetic wave phenomena in media structured on the same lengthscale as the wavelength, and is also a very active area of study in our group. Thesis projects on these current topics of research are available on request.

The research of the group of S. Mishra focuses on the design, analysis and efficient implementation on state of the art high performance computing platforms, of robust numerical methods for nonlinear partial differential equations, particularly of the hyperbolic type, and their application in fluid dynamics, plasma physics, astrophysics, climate science and geophysics.
We also address fundamental mathematical questions of well-posedness of nonlinear hyperbolic PDEs, particularly in the context of novel solution frameworks such as statistical solutions.
Numerical methods, of the finite volume, finite difference, spectral and discontinuous Galerkin finite element type are developed in the group. Another focus area is on computational uncertainty quantification i.e efficient calculation of uncertainties in the solutions of PDEs that are driven by stochastic initial/boundary conditions, parameters and chaotic dynamics.
Student projects for Bachelor, semester and Masters thesis are available on the whole range of topics from addressing fundamental mathematical questions to the design of efficient algorithms, HPC implementation and interesting applications.
Student projects are available in Mathematical Analysis (error estimates) and Computer Implementation of efficient direct and inverse problem solution for deterministic and stochastic Partial Differential Equations with either many (several hundred) parameters, or with solutions on very high dimensional state- and phase spaces.
