Profile Summary

Scientist and Engineer specializing in electrochemical energy storage systems, catalytic nanomaterials, and advanced sensor platforms. I deliver precision solutions for complex challenges in clean tech, energy storage, biosensing, and green manufacturing. With a background in both academic and startup environments, I’ve led cross-functional R&D teams, designed and build bespoke instrumentation, and secured competitive research funding totaling over €300,000. My expertise spans electrochemical methods (CV, EIS, DPV), nanofabrication and synthesis, and surface/interface analysis (XPS, SEM, TEM). I’ve built microbial fuel cells for hypersaline wastewater treatment, developed scalable polymer nanocomposites for nutrient detection, and co-invented vapor-phase water electrolysis prototypes. I've previously consulted on projects for clients in green steel, food safety, and ammonia for hydrogen storage. Clients can expect technical depth, startup agility, precision prototyping and data-driven analysis. Currently based in Berlin, also am legally able to work on contracts in the US and Hong Kong.
