- I have worked on fitting fatigue, plasticity, and creep models to isotropic as well as single-crystal materials.
- To achieve this, I developed a custom tool that accurately processes material test data and fits it to these models.
- Integrated the calibrated models into the material database, which is further used by analysts to calculate damage and assess the remaining useful life of components in deployed engines, enabling data-driven maintenance and lifecycle decisions.
- Designed and developed a desktop application to process raw data, including stress and temperature inputs, and compute damage outputs such as fatigue life, rupture life, and hot corrosion life, with functionality to visualize these results as 3D mesh contours.
- Created a desktop application to map pressure data from CFD point clouds onto a structural mesh model, enabling users to visualize and compare the mapped pressure with the actual pressure data.

- Enhanced the design of engine core components by performing thermo-mechanical fatigue (TMF) analysis.
- Proposed a partial component bench test setup for fatigue life evaluation, replicating stress gradients observed in full components at critical locations, significantly reducing the need for costly full-engine tests.
- Conducted Linear Elastic Fracture Mechanics (LEFM) simulations to assess the impact of existing cracks on component life.
- Improved finite element simulation predictions by performing strain correlation with experimental test data.
- Collaborated closely with designers to propose design concepts that meet objectives such as fatigue life, sealing pressure, and thermal performance.
- Developed a desktop application for automated crack implantation in component meshes.
- Designed a desktop application to map convection boundary conditions on rotating engine valves, enabling transient heat transfer simulations.
- Created a machine learning-based risk assessment tool to evaluate the effects of uncertainties in geometry, assembly loads, and material properties on component life.
- Reviewed peer work as part of quality assurance practices, and mentored team members in scripting and automation techniques.

- Conducted modal analysis to identify potential interference between local frequencies and engine order frequencies.
- Performed static G-load analysis to evaluate stresses resulting from structural loads.
- Applied machine learning-based sensitivity analysis, offering a modern alternative to traditional Sobol indices.
- Developed a Python module to streamline the creation of pre-processing scripts for the Abaqus solver.
- Designed and implemented a desktop application for FEA pre- and post-processing tasks, including convection boundary condition scaling, generating 2D skins from 3D elements, mapping point cloud data to element faces, and converting 3D element ODB files into shell element ODB files for Abaqus.
- Collaborated with the team to implement automation solutions, enhancing process efficiency, and workflow optimization.
