Brief Biography

Nageh Allam received his PhD in materials science and engineering from Pennsylvania State University and pursued his postdoctoral studies at both Georgia Institute of Technology and Massachusetts Institute of Technology (MIT). He joined the faculty at The American University in Cairo (AUC) as an assistant professor in Fall 2011. He was promoted to the rank of associate professor with tenure in 2015.  Allam’s research is multidisciplinary in nature as it is at the interface between nanoscience, physics and chemistry. It deals with the development of a set of synthetic and fabrication techniques to obtain well-designed nanostructured materials with composition, size and shape control for use in energy conversion and storage, sensors applications, biomedical applications, among others. The research comprises both experimental and theoretical activities. Allam is a member of the American Physical Society, the American Nano Society, the Materials Research Society, the Electrochemical Society, the American Society for Testing and Materials International, the Max Planck Society for the Advancement of Science, and has recently been elected to the Arab-German Young Academy of Sciences and Humanities (AGYA). Allam has published more than 100 papers in reputed peer-reviewed international journals and has authored more than 90 conference articles. He serves as an editorial board member of a number of renowned journals. He is the recipient of the Ford Foundation international graduate fellowship, RAK-CAM postdoctoral fellowship, the World Academy of Sciences (TWAS) Yong Scientist Award, the Showman Foundation Award in Applied Sciences, the State of Egypt Award in Advanced Technological Sciences and the AUC Excellence in Research and Creative Endeavors Award.
