Profile Summary 

Research Interests

Machine Learning, Computational Fluid Dynamics

I am currently focused on how Machine Learning actually works if it works at all. 

Till very recently, my main interest was CFD. I was particularly fond of using OpenFOAM, an open source package for discretizing PDEs using Finite Volume Method. We worked on developing the following modules in OpenFOAM: Shape Optimisation codes, Immersed Boundary Methods. We are also extensively using the newly developed OpenFOAM's overset mesh support to study designs of Vertical Axis Wind Turbines (VAWT).
