Assoc.Prof.Dr./Marwa A.A. Fayed is interested in Phytochemical and Pharmacognostical studies of medicinal plants, isolation of bioactive constituents from different natural sources using advanced chromatographic techniques (separation on VLC, column chromatography using different adsorbents as RP, Sephadex, Cellulose or Polyamide and separation using PC), structure elucidation of naturally isolated compounds using different spectroscopic techniques.
- Ph.D. in Pharmaceutical Sciences (Pharmacognosy), Assiut University (2013).
- M.Sc.in Pharmaceutical Sciences (Pharmacognosy), Assiut University (2004).
- B.Sc. in Pharmaceutical Sciences, Assiut University (1998).
- Appointed as Lecturer of Pharmacognosy and Phytochemistry, Faculty of Pharmacy, University of Sadat City  in December 2016.

- Appointed as Associate Professor of Pharmacognosy and Phytochemistry, Faculty of Pharmacy, University of Sadat City  in April 2020.

- Appointed as Head of Pharmacognosy and Phytochemistry, Faculty of Pharmacy, University of Sadat City in July 2020.

- Member of the academic editorial board of the Universal Journal of Pharmaceutical Research (UJPR), 

- Associate editor in the Journal of Agricultural Sciences and editor in Pharmaceutical Sciences & Analytical Research Journal.

- A reviewer in many prestigious journals as: molecules, biomolecules, Natural Product Research, Journal of Inflammation Research, Indian Journal of Natural Products and Resources and many others.
- More recently, has developed a significant interest in monitoring the pharmacological effects and mechanism of action of different classes of chemical compounds isolated from natural sources and their possible role in medicine.
Research/scholarly interests:
- Understanding and having good skills in structure elucidation of the isolated compounds from any natural source based on classic and recent spectroscopic methods: (UV, IR, 1H-NMR,1H-1H COSY, 13C-NMR, DEPT 13C-NMR, HSQC, HMQC, EI-,+FAB- and MALDI-TOF-MS) in addition to the comparison of the physical, chemical and chromatographic characters of these compounds with authentic samples.
- excellent skills in botanical studies of medicinal plants through their macro- and micromorphological characters of their different parts (leaves, roots, seeds…..etc.).
- excellent skills in extraction, fractionation, and isolation of active constituents from natural medicinal plants.
