Research and technical work at the Chair of Energy Technology, spanning thermal system simulation, technical documentation, and knowledge infrastructure development. Thermal System Simulation (September 2023 to August 2024): Modeled a geothermal hybrid absorption-compression heat pump using a mixture of ammonia and water in Aspen Plus, for integration into the Duisburg district heating network at a 55 degree Celsius source temperature. Developed integration strategies with a projected 15 percent improvement in coefficient of performance over conventional heat pump solutions through parametric thermodynamic analysis. Contributed to bachelor's thesis research on comparative thermodynamic simulation of heat pump systems with ammonia and ammonia-water mixtures. Technical Documentation and Knowledge Management (October 2024 to present): Authored 80+ technical articles for the EnArgus energy lexicon on heat pump engineering, hydrogen technology, fuel cell systems, and renewable energy, translating complex research into clear and structured content for academic and industry audiences. Built and led the development of an internal knowledge base that significantly improved team access to technical information and reduced time spent searching for reference material across ongoing research projects. Supported research communication for the energy technology department, contributing to its visibility in topics aligned with Germany's Energiewende. Skills: Aspen Plus, Heat Pump Technology, Thermodynamics, Technical Writing, Renewable Energy

Embedded within an engineering team developing simulation models and techno-economic analyses for advanced hydrogen and fuel cell energy systems. • Built and validated a MATLAB/Simulink dynamic simulation model for a hydrogen PEM fuel cell hybrid system. Reduced simulation error by 25% through iterative parameter tuning, model refinement, and calibration against real system reference data. • Conducted techno-economic and environmental assessments for energy system concepts at feasibility stage, delivering structured analysis reports that directly informed project planning and concept selection decisions. • Standardized internal technical documentation processes, improving the traceability of engineering decisions and enabling faster knowledge-sharing across the team.

Specialized in thermal systems and energy engineering, with a final thesis focused on comparative heat pump simulation. Thesis: Comparative Thermodynamic Analysis of Heat Pump Systems Using Ammonia and Ammonia-Water Mixtures Built full thermodynamic cycle models for both refrigerant configurations using Aspen HYSYS and MATLAB. Analyzed COP, system efficiency, environmental impact (GWP, ODP), and economic viability across multiple operating scenarios. Findings provided direct guidance for low-carbon heating system design and refrigerant selection.

Completed substantial coursework in electrical engineering before relocating to Germany to pursue a full Mechanical Engineering degree. Core subjects studied included electrical machines, control systems, circuit analysis, thermodynamics, and fluid mechanics. This foundation provided valuable cross-disciplinary exposure that continues to inform my systems-level thinking in energy technology roles.
