About me

Hello World!

I am a postdoc in the Climate Physics department of MPI-M. I am a part of the EU funded NextGEMS project. My postdoc supervisor is Prof. Dr. Bjorn Stevens.

I work on understanding the processes that result in the breakdown of the Intertropical Convergence Zone (ITCZ) using the km-scale coupled atmosphere-ocean-land simulations that are produced as a part of the NextGEMS project. I am also interested in understanding the differences in the propagation mechanisms of the ITCZ at different longitudes. 

Previously, I was a Alexander von Humboldt postdoctoral fellow at TU Darmstadt where I derived scaling laws for compressible turbulence statistics using Lie symmetries.  

Research interests

I am interested in all things fluid dynamics - conducting and non-conducting flows, incompressible and compressible flow regimes, instability and turbulence, geophysical, astrophysical and engineering flows. 

For my PhD, I worked on understanding the effects of magnetic field and compressibility on the instability due to shear in conducting flows. This has applications both in Astrophysical (jets) and Engineering (plasma propulsion) contexts. Please see the following publications 1, 2, 3 and 4 that I published as a part of this work. 

In my subsequent postdoctoral work, I got interested in turbulence in compressible flows. I worked on understanding the impact of pressure-dilatation on spectral energy transfer (link). As a part of my Humboldt fellowship, I derived two unified frameworks (using probability density functions and characteristic functions) through which one can obtain an equation for any order of compressible statistics (link). I derived the symmetries for the characteristic function framework here
