Biography
- March 2017- till current: Associate Professor and Postdoctoral Researcher, Department of Pharmacognosy, Faculty of Pharmacy, Ain Shams University, Cairo, Egypt.
- Ph.D. Pharmacognosy, Faculty of Pharmacy, Ain Shams University, Cairo, Egypt (August, 2011). Channel System and Joint Supervision Scheme (Ain Shams University and Department of Chemistry, Turku University, Finland (from March 2008-March 2010). This international cooperation was established from 2008-till current.
RESEARCH EXPERIENCE:

 Isolation and identification of different classes of natural compounds (saponins, sterols, terpenoids, essential oils, alkaloids, phloroglucinol derivatives, chromones, ellagitannins, gallotannins, phenolics, and flavonoids) of promising biological activity from herbal medicines and microbial organisms employing the different methods of chromatographic analysis (TLC, CC, HPLC, chromatotron, GC.. etc)

 Determination of the biological activity of the extracts and isolated compounds obtained from herbal medicines and microbial organisms employing in-vitro and in-vivo models: Gastroprotective, anti-inflammatory, hepatoprotective anti-tumor, cytotoxic, anti-lipidemic, anti-diabetic, acetylcholinesterase inhibition, anti-bacterial biofilm, antimicrobial, molluscicidal and antioxidant activities following bioactivity directed fractionation of extracts.

 Structural elucidation of different classes of natural products using different techniques (LC-PDA-ESI/MS/MS, GC/MS, UV, 1D and 2D-NMR, High resolution MS, IR, …etc).

 Analytical and preparative scale purification techniques using HPLC.

 Standardization and quality control of herbal medicines using chemometric analysis.
