Ph.D. from PHYSICS
05.2017 - 01.2024

University Overview

  • Thesis: Study of aberrations from the stigmatism theory.
  • Theoretical Research & Publication: Conducted an in-depth theoretical investigation on optical aberrations in systems composed of Descartes ovoids. Published 8 peer-reviewed journal articles in leading optics journals, covering topics such as Stigmatism in optical systems, aplanetism and conditions for aplanatic imaging, design of stigmatic optical systems, strictly aplanatic optical systems, and primary aberration analysis in systems composed of Cartesian surfaces.

University Overview

  • Thesis: Implementation of a point source in a discontinuous Galerkin 2D elastic wave modeling system.
  • Research & Theoretical Development: Conducted a research study on the numerical modeling of elastic wave propagation in 2D heterogeneous media. Focused on the accurate implementation of point source terms in Discontinuous Galerkin (DG) frameworks, a challenge due to the singular nature of point sources in finite-element methods.

Ensured stability and convergence across various grid configurations and boundary conditions. Designed modules for mesh generation, material property assignment, and time-stepping algorithms.
  • Technical Implementation: Python was used for high-level orchestration, visualization, and parameter configuration. C++ handled the low-level, performance-critical routines for numerical integration, matrix assembly, and time evolution. Validated the implementation through benchmark comparisons, including analytical solutions and known synthetic models.
  • Visualization & Analysis: Developed tools to visualize the wavefield propagation and evaluate model behavior over time. Conducted error analysis and convergence tests to verify the reliability of the point source implementation.
  • Research Outcomes: Provided a robust and flexible numerical tool for 2D elastic wave modeling with accurate source representation, applicable to seismology, non-destructive testing, and material analysis. Contributed to advancing the usability of DG methods in wave propagation problems with singularities or localized inputs.
