Colloidal & Biopolymer Formulation Consultant | Structure–Function Engineering & Performance Optimization

Profile Summary

I am a biomolecular physicist and formulation scientist specialising in biopolymers, hydrogels, colloidal systems, and structure–function engineering. I help companies design, optimise, and troubleshoot complex biomolecular and colloidal formulations by translating molecular interactions into predictable material performance. My expertise includes charge-driven assembly, polyelectrolyte complexation, rheology, interfacial behaviour, and calorimetric analysis. Working at the interface of academia and industry, I develop mechanism-driven solutions for challenges in food, biomedical, and advanced materials sectors. My projects have included hydrogel optimisation, colloidal stability improvement, metal–biopolymer interaction analysis, surgical fluid development, and waste stream valorisation. I deliver clear technical insight, practical formulation strategies, and actionable recommendations to improve performance, stability, and scalability.
