Jaafar El-Awady

Associate Professor

Research Interests

Multiscale materials modeling, damage and fracture mechanisms of materials in mechanical design, material degradation in extreme environments, nano-materials and structures, impact dynamics and wave propagation.

Jaafar El-Awady is an associate professor in the Department of Mechanical Engineering, where he leads the Computations and Experimental Materials Engineering Laboratory. The goal of his research group is to enhance the field of Materials-by-Design by moving from empirical, trial-and-error development techniques of materials to a combination of state-of-the-art multiscale computational methods and experimental techniques that can lead to next-generation materials with superior performance. El-Awady received a BS in 2001 and MS in 2003 from Cairo University, Egypt, and his PhD in Aerospace Engineering from the University of California, Los Angeles in 2008. Prior to joining Johns Hopkins in 2010, he was a visiting scientist with the Materials and Manufacturing Directorate at the Air Force Research Laboratory.
