Dr. Ahmed R.に依頼

Egypt

Decoding Molecules. Designing Cures. Modeling/Spectroscopy Expert with 15+ years of experience in scientiic research

プロフィール概要

I conduct cutting-edge scientific research at Egypt’s National Research Centre (NRC), specializing in ab initio calculations, molecular docking, and advanced spectroscopy. As a core member of the NRC’s Molecular Spectroscopy and Modeling Laboratory, I provide precise analytical measurements and strategic consultancy to academia and industry—turning spectral data and computational models into actionable insights for drug discovery, materials science, and molecular design. My work bridges theoretical innovation and real-world application, leveraging state-of-the-art tools (Gaussian, AutoDock, Biovia) to solve complex chemical challenges.
