I am a third-year Ph.D. Student at NC State University. My research interests include Numerical Modelling of Water Systems, Ocean and Coastal Engineering, Offshore Structures and Dynamic Response of Structures.

During my masters at National Institute of Technology, Calicut, my project dealt with finding the Response of Semi-Submersibles under Multi-Directional seas. The semi-submersible was modeled as a rigid body with six degrees of freedom and the multi-component mooring lines as nonlinear springs at its fair-lead point. Modified Morison equation was employed to find the wave forces and the dynamic equilibrium equation was solved in time domain using an iterative procedure by Newmark-Beta method.

As part of my research at NC State, I am now involved in the NC Sea Grant project “Strengthening the Hurricane Wave and Surge Forecast Guidance provided to Coastal Communities in North Carolina.” In this project, we were trying to improve the accuracy of storm surge predicted for the North Carolina region. This is done by refining the mesh used for running the coupled ADCIRC-SWAN model at selected regions based on the errors in mass conservation.

I am also a part of the DHS project “Improving the Efficiency of Wave and Surge Models via Adaptive Mesh Resolution.” In this project, we are trying to implement an adaptive, multi-resolution approach to increase resolution during a simulation. We will be starting with a relatively coarse resolution mesh and as the storm approaches, we will be adding regions from a fine resolution mesh. We will be also trying to optimize the use of computational resources through dynamic load balancing in which we will be reallocating computational resources to improve parallel efficiency.
