Professor Peralta joined Arizona State University's School for Engineering of Matter, Transport and Energy in 1998 and received the National Science Foundation (NSF) Early Career Award in 2000 and the Senior Orr Award for best paper in fatigue and fracture from the ASME Materials Division in 2004. He was associate editor of the ASME Journal of Engineering Materials and Technology and has been a visiting scientist at Los Alamos National Laboratory since 1999. His research focuses on mechanics of materials, fatigue and fracture of metallic alloys, dynamic and shock loading of metallic and intermetallic materials with emphasis on effects of anisotropy and grain boundaries on mechanical behavior and failure.
Peralta has a bachelor’s degree in mechanical engineering from Universidad Simón Bolívar in Caracas, Venezuela, and received both his master's degree in mechanical engineering and applied mechanics and his doctoral degree in materials science and engineering from the University of Pennsylvania. After completing his doctorate in 1996, he was a director-funded postdoctoral fellow at the Center for Materials Science at Los Alamos National Laboratory.
