👋 Hi! I’m Jubica, Welcome to my professional portfolio. Here is a brief overview of me:

I am a Materials Engineer dedicated to bridging the gap between lab-scale experiments and industrial reality. By translating complex experimental findings into detailed failure assessments, I provide the technical insights necessary to support safe, and reliable energy infrastructure.

My expertise lies in evaluating material performance under extreme conditions specifically high-pressure and corrosive environments to ensure long-term structural reliability. By integrating advanced microstructural characterization (SEM, EBSD, XRD) with mechanical testing, I deliver the validation necessary for lifecycle assessments, predictive maintenance, and the refinement of industrial design codes and safety standards. I have a proven track record of leading technical projects from initial concept to proven results, ensuring critical infrastructure remains resilient in a changing energy landscape.

Research contribution from Doctoral work 🎯

• My doctoral research investigates the impact of hydrogen on pipeline steels to support material selection for safe hydrogen service.
• A key focus has been to establish a screening methodology by identifying critical material parameters that influence hydrogen sensitivity.
• I have developed a gaseous charging method using autoclaves to study hydrogen uptake under static conditions.
• I have also explored the role of oxygen as a gaseous inhibitor to limit hydrogen absorption, with a focus on concentrations, temperatures, and pressures closer to real-world applications.
• I have studied the effects of cathodic overprotection on pipeline steels by investigating different charging current densities.
• I have analyzed cross-sections of various pipeline steel base materials.
• I have developed the hydrogen microprint technique in-house to study the preferential hydrogen sites in steels.

Technical Skills 🔧

My expertise covers a range of advanced methods for materials characterization:

• Microstructural Characterization: Light Optical Microscopy (LOM), Scanning Electron Microscopy (SEM), Electron Backscatter Diffraction (EBSD), Energy Dispersive X-ray Spectroscopy (EDS), X-ray Diffraction (XRD) and Positron Annihilation Spectroscopy (PAS).

My Doctoral research strengthened me with hydrogen characterization techniques:

• Hydrogen Characterization: Electrochemical Hydrogen Permeation, Thermal Desorption Spectroscopy (TDS), electrochemical hydrogen charging, gaseous hydrogen charging setups, and the hydrogen microprinting technique.
• Experimental data underwent rigorous analysis to interpret the findings and establish their physical implications.
• Quantification of microstructure (size, density and morphology), hydrogen diffusivity from permeation experiments, evaluating hydrogen trapping kinetics.
