Ivana Jovanovic Buha, M.Sc. (hons)

Background

• Doctoral candidate, CIT Graduate Center,  TUM Graduate School - 
• Research Associate (Wissenschaftlicher Mitarbeiter) at TUM SCCS since June 2018
• M.Sc. with Honours in Computational Science and Engineering, Technical University of Munich, 2018
• Diploma in Electrical Engineering, University of Belgrade, Signals and Systems Department, 2014

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
