PhD candidate in computational solid mechanics with a background in computational materials science and mechanical engineering. My research focuses on thermo-mechanical finite element simulation of heterogeneous materials, combining microstructure-resolved modeling, cohesive interface formulations, and Python-driven virtual laboratory workflows for simulation-based material evaluation. Prior to academia, I worked as a software developer for five years, giving me a practical grounding in structured software development alongside my research work.

PhD research within DFG Research Training Group GRK-2802. Focus: thermo-mechanical finite element simulation of heterogeneous MgO–C composites within a virtual laboratory framework connecting microstructure generation, coupled thermal-structural FEM, and simulation-driven performance evaluation.

  • Developed a microstructure generation tool using statistical phase distributions and Laguerre–Voronoi tessellation for automated FEM model generation of heterogeneous composite structures.
  • Formulated a coupled thermo-mechanical cohesive interface model capturing damage initiation and interfacial failure driven by thermal expansion mismatch.
  • Introduced a fracture-based parameter for numerical assessment of thermal shock resistance incorporating crack length and crack density.
  • Integrated microstructure generation, constitutive modeling, and Python-based pre-/post-processing into a virtual laboratory framework for reproducible parametric studies.
