CV

Research Engineer — CAE Expert (R&D)

Global Engineering and Materials, Inc.

Lead CAE for digital twin and AI/ML-enabled engineering programs. Built end-to-end digital twin software framework with NIAR — integrating physics-based process simulation, sensor data, and validation workflows. Architected ML-powered software combining transformer language models with Abaqus-based simulation for polymer property prediction and inverse design. Delivered digital material generation toolkit predicting ply-level elastic, strength, and thermal properties of composites with explicit defect effects.

Mechanical Engineer (R&D)

Global Engineering and Materials, Inc.

Built defect-aware composite simulation framework for aerospace structures — chaining global-to-local aircraft wing analysis, XFEM-based fatigue crack growth, CDM progressive damage, and CFD-driven thermal loading into a unified manufacturing-to- in-service-failure pipeline.

Associate Material Engineer (R&D)

Global Engineering and Materials, Inc.

Characterized fabrication- and service-induced defects in composite materials. Built defect-informed geometry models and physics-based material models. Developed structural-level FE frameworks that explicitly incorporate process-induced defects for realistic performance prediction and design assessment of aerospace components.

Graduate Research Assistant

Wichita State University

Performed nonlinear FEA (MSC Marc, HyperMesh) and micro–macro multiscale modeling of composite honeycomb cores; developed custom FORTRAN subroutines for anisotropic hyperelastic creep. Executed full mechanical and thermal characterization (fatigue, fracture, SBS, DSC, CTE, stress relaxation) of composite panels and translated experimental outputs into validated FE model inputs.

Engineering Intern — Design and Stress Analysis

CEMILAC (DRDO)

Performed structural FEA on low-pressure turbine blades using ANSYS. Computed margin of safety, evaluated design allowables, and analyzed stress concentrations from notch geometries (V-cut, U-cut) under representative aero loading conditions.
