Dr. Ahmed Sobhy Abdelrahim Abdallah Darwish is a highly qualified analytical chemist with a strong academic foundation, holding a B.Sc. in Chemistry–Physics from Zagazig University, a diploma in analytical chemistry with Excellent grade, a pre-master qualification scoring 98%, and a completed M.Sc. in analytical chemistry, while currently pursuing a Ph.D. in the same field. His credentials include a valid TOEFL certificate demonstrating doctoral-level proficiency. He possesses extensive professional experience across the pharmaceutical industry, beginning as a QC chemist and advancing to senior roles in stability and methodology, ultimately becoming Deputy Manager of Labs Development at EIPICO, where he leads a team of ten staff members and oversees method development, comparative in vitro testing, and stress stability research. Dr. Darwish has distinguished technical negotiation capabilities with major international pharmacopoeias including USP, EP, BP, and regulatory bodies such as SFDA, Romanian FDA, and Jordan FDA. His research portfolio includes completed and published works on eco-friendly, sustainable, and greenness-evaluated HPLC methods, such as stability-indicating assays for piracetam, vincamine, LEVOMENOL, NETILMICIN, butylated hydroxytoluene, retinol, tocopherol, colchicine, khellin, valsartan, sacubitril, and shelf-life HPLC methods for sugammadex sodium. He has authored and co-authored 7 peer-reviewed publications, with 33 citations from 22 documents and an h-index of 3 (Scopus ID: 59519037100), reflecting growing international recognition in green analytical chemistry and pharmaceutical analysis. His consultancy and technical leadership span Delta Pharma, Grand Pharma, Averroes Pharma, Al-Debeiky Pharma, and Copad Pharma, covering QC operations, stability programs, method development, and finished product evaluation from 2009 to 2021, before joining EIPICO in a senior R&D role. His expertise includes advanced operation of HPLC, GC, ICP, AAS, UV-Vis, and other analytical platforms essential for pharmaceutical quality assessment. Dr. Darwish serves as a reviewer for multiple international journals including European Journal of Scientific Research and Reviews, Results in Chemistry (Elsevier), Bulletin of the Chemical Society of Ethiopia, Asian Journal of Cardiology Research, and Asian Journal of Medical Principles and Clinical Practice, and acts as a Google Scholar and Crossref reviewer for ETERNO PRESS Scholar Council. His collaborative achievements include participation in the USP QualityAssist beta program (2025), contribution to BP sustainability guidance through two accepted ecofriendly case studies (2024), liaison with the Egyptian Pharmacopoeia since 2024, contributions to BP Research Users in 2023, and involvement in USP’s 2021 Dexamethasone product requirements project. Dedicated to green chemistry, pharmaceutical analysis, and sustainable method development, Dr. Darwish continues to advance analytical innovation and regulatory-compliant pharmaceutical research.
