Senior Biotechnologist | Leader in Natural Product Research, Advanced Spectroscopy, and Applications in Health &Industry

Profile Summary

My research interests focus mainly on Marine Biotechnology. Atpresent, I am working in natural products extraction and isolationof pure bioactive compounds from various marine organismsthrough chromatography separation (normal phase columns) ofcrude extracts, then doing full characterization via spectroscopictechniques (NMR, FTIR and MS). In the same direction, I amdoing some applications (Anticancer, Antimicrobial, Antioxidants,Cytotoxicity, …. etc.) to the isolated compounds.
