Atallah F. Ahmed

Bio
A.F. Ahmed earned his Ph.D. degree in Pharmacognosy and Natural Products Chemistry at Okayama University, Okayama, Japan (1993) and pursued his postdoctoral research in the Department of Marine Biotechnology and Resources at National Sun Yat-sen University (NSYSU), Kaohsiung, Taiwan (2001-2006). He spent most of his career at Mansoura University, Egypt before getting hired as a professor of Pharmacognosy and Natural Product Chemistry to join the College of Pharmacy at King Saud University, Saudi Arabia in 2010. He has published more than 90 papers, in the field of marine and terrestrial natural products and evidence-based herbal medicine, in reputed journals. He has been serving as a PI in funded research groups "Theme: Bioactive Natural Products" and ISPP projects funded by King Saud University; a reviewer for several field-related ISI journals and an external reviewer for research project proposals funded by many Saudi universities and KACST and for staff promotion files.
