Background

Research interests

My research focuses on applied and computational mathematics, particularly on uncertainty quantification (UQ), modeling and system identification, inverse problems, and data-driven model learning. The main applications driving my research are from hydrology. More precisely, in my work, I am bridging the gap between theoretical work on High-dimensional Uncertainty Quantification and Bayesian Inversion, applied to relatively simple simulation models, and more complex real-world problems.

  • High-dimensional Forward Uncertainty Quantification and Sensitivity Analysis (mainly, analysis of conceptual distributed hydrologic models)
  • Sparse Grids Methods
  • Inverse problems - Bayesian Inference
  • Machine Learning

Open student projects

If you are interested in a student project (Bachelor's or Master's Thesis or anything else), it is the best to contact me directly. Here is the list of some projects that I would offer at the moment (the list is not exhaustive):

  1. "UQ and SA of Hydrologic model HBV using pyApprox software tool"

  2. "Calibration under uncertainty of the HBV hydrologic model using a parallel implementation of the Metropolis-Hastings algorithm"

  3. "Running Uncertainty Quantification simulations using the UM-Bridge software tool: application on a hydrologic model"

  4. Mapping sparse grid interpolation to pseudospectral approximation 

  5. Calibration under uncertainty of the simple hydrologic model using different software tools, e.g., DREAM (Dakota), MUQ

You can also come to my office and discuss possible topics. 

See also the list of Student Projects at our chair, e.g.,  https://www.in.tum.de/i05/jobangebote-studentische-projektarbeiten/job-offers-student-projects/uncertainty-quantification/

Do you want to know what other students are working on in our chair? You are warmly encouraged to attend their presentations at the SCCS Colloquium! Come to get ideas, meet your potential supervisor, or to learn from the style of others for your own presentation.
