I am a fifth year Ph.D. student in Coastal Engineering 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 thesis 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 then used to find the wave forces and the dynamic equilibrium equation was solved in time-domain using an iterative procedure by Newmark-Beta method.
During my initial years of research at NC State, I was involved in the NC Sea Grant project “Strengthening the Hurricane Wave and Surge Forecast Guidance provided to Coastal Communities in North Carolina.” The aim of this project was to improve the accuracy of storm surge prediction for the North Carolina region. This was done by refining the mesh used for running the coupled ADCIRC+SWAN model at selected regions based on the errors in mass conservation. I was also a part of the DHS project “Improving the Efficiency of Wave and Surge Models via Adaptive Mesh Resolution, that dealt with hindcasts of winds and surge during Hurricane Matthew (2016). Here, we looked at the influence of storm timing and forward speed on flooding during a hurricane. The contribution of non-linear interaction between tides and surge to the total water levels were also quantified.
My current research deals with implementing a multi-resolution approach to reduce the computational workload of storm surge models, and is also being funded as part of the above DHS project. Rather than using a single high-resolution mesh throughout the simulation, different meshes of varying resolution will be used depending on where the storm is at that point in time. A coarse-resolution mesh without extensive coastal detail can be used when the storm is far away. As the storm approaches the region of interest, the results can be mapped on to a high-resolution mesh. The simulation will then continue on the fine mesh, thus providing high-accurate results for that coastline. This technique will thus enable storm surge forecasting with both ensemble calculation and high-resolution capabilities.
Aside from research, I enjoy being physically active whether it be playing soccer or going for hikes and runs. I also love watching sports, hanging out with my friends, playing counter-strike, pencil sketching, and visiting new places.
