About me

I obtained my diploma at the Department of Mathematics and Informatics, University of Banja Luka, under the supervision of Dr. Vladimir Jovanovic.

Currently I work as a PhD student at the Section of Applied Mathematics (AAM), University Freiburg, under the supervision of Prof. Dr. Dietmar Kröner. The areas of my research are in the field of numerics for nonlinear partial differential equations. In particular, these equations are the compressible Euler and Navier-Stokes equations and their adjustments which include different species needed for modelling atmospheric flows (dry air, water vapor, cloud water and rain).

 

Projects

I am involved in the DFG Priority Program (SPP)
1276 MetStröm: Multiple Scales in Fluid Mechanics and Meteorology .

The subproject of the SPP 1276 on which I am working on is
Adaptive numerics for multiscale phenomena.
