Israel Kellersztein is an Assistant Professor in the Department of Materials Engineering at Ben-Gurion University of the Negev. His research focuses on how hierarchical structure and composition govern the mechanical behavior of biological and synthetic materials.

His work integrates experimental mechanics, multiscale characterization, and additive manufacturing to establish structure–function relationships in complex material systems. He has contributed to the understanding of hierarchical architectures in arthropod exoskeletons, including non-classical helicoidal organizations linked to mechanical behavior.

Dr. Kellersztein received his PhD from the Weizmann Institute of Science and conducted postdoctoral research at the California Institute of Technology as a Fulbright Scholar. His research bridges fundamental biological materials science with the design of architected and sustainable materials.
