Kamel A. Abd-Elsalam is currently a Research Professor at the Plant Pathology Research Institute, Agricultural Research Center, Giza. He earned his PhD in molecular plant pathology through a joint program between Christian Albrechts University of Kiel, Germany, and Suez Canal University, Egypt, followed by a postdoctoral fellowship at Christian Albrechts University. His research focuses on nanobiotechnology applications in agriculture and plant protection, and he has authored numerous peer‑reviewed articles and edited books with major international publishers. His scientific contributions have been recognized nationally and regionally, including awards from the Federation of Arab Scientific Research Councils for research excellence in biotechnology and the Egyptian State Award for Agricultural Scientific Excellence from the Academy of Scientific Research and Technology. He has been recognized among the world’s top 2% most influential scientists in nanobiotechnology for three consecutive years (2021–2023), according to global rankings developed by Stanford University. Since 2019, he has served as the Editor-in-Chief of two Elsevier book series, Nanobiotechnology for Plant Protection and Genome Modified Plants and Microbes in Food and Agriculture.
