PhD Chemist | Expert in Formulation, Analytical Chemistry, and Scientific Writing Freelance Chemist | Formulation, Data

Profile Summary

I hold a PhD in Inorganic Chemistry with a strong background in formulation development, analytical techniques (IR, NMR, UV-Vis), and inorganic/organic synthesis. My research focused on the design and structural characterization of metal complexes and hybrid materials, using advanced spectroscopic and crystallographic methods. I have solid experience in spectroscopic data analysis, thermal behavior studies (TGA/DSC), and the interpretation of experimental results for scientific publications. I have authored and contributed to several peer-reviewed research articles. As a freelance expert, I offer services in scientific writing, manuscript editing, literature review, formulation consulting, and technical reporting. I bring a rigorous, detail-oriented approach and adapt my work to both academic and industrial needs. I am ready to collaborate on your project with precision, scientific insight, and full confidentiality.
