PhD Surface Chemistry Consultant | Antifouling Coatings | Polymer Brushes | Expert R&D Solutions

Profile Summary

I’m a PhD chemist with 15+ years of experience in polymer science, surface chemistry, and advanced coatings. I specialize in antifouling surface modification using polymer brushes (RAFT, SI-ATRP) for applications in biotech, diagnostics, filtration, and materials engineering. I help renowned companies and research teams develop and optimize functional coatings on glass, silicon, metal oxides, and polymer surfaces. My services include: R&D consulting in polymer chemistry and nanocoatings Experimental design and protocol development Surface functionalization for biosensors, membranes, and lab-on-chip systems Scientific writing, publications, Based in the EU, I collaborate globally with companies, research teams, and product developers seeking expert guidance or long-term support. Let’s discuss how I can help bring your innovation to the next level.
