Professional Summary
Dr. Allam A. MEGAHED, is a Professor (Full) of Plant Pathology (Faculty of Agriculture, Damietta University, New Damietta, Egypt), postdoctoral in Department of Molecular Biotechnology (Graduate School of Advanced Sciences of Matter, Hiroshima University, Japan) during 2014, and his previous position at National Research Centre (affiliated with the Egyptian Ministry of Higher Education and Scientific Research, Egypt). He was published 35+ papers (indexed in Scopus, and most of them are ranked in the top tier), holder 13 new gene sequence in GenBank. He is having 23 years of research experience including 17 Years teaching experience, international trainer for DPIC by GTZ. He serves on 14 national and international scientific and educational societies including 3 Japanese society committees. He serves on major scientific committees in Egypt and abroad coordinates, joined 4+ projects, won several awards, and coordinates 6 international conferences. He was participated in 60+ conferences and symposiums, and as an editor and reviewer for 15+ scientific Journals. He has supervised 8 graduate students. Dr. MEGAHED`s research is focused on solving real agricultural problems particularly in the tropical and Subtropical Regions. A major part of his research has been concentrating on Biological Control and Systemic Acquired Resistance (SAR) of various plant diseases pathogens (Phyto-viruses, Phyto-fungi, Phyto-bacteria and Phyto-nematodes) of global importance, and beside his experience in SDS-PAGE technique, protein chromatographic purification (DEAE-Eellulose and gel filtration columns), enzymes kinetic activity and isoenzymes patterns, ELISA, PCR, RT-PCR and DNA Hyperdization. He has provided training to farmers and self-help groups in many villages in Damietta, Egypt districts on plant diseases management and control.
