Curriculum Vitae

I obtained my PhD degree from Saint Petersburg State University for the research devoted to the development of the approaches to control the mechanical performance of thin amorphous-crystalline shape memory ribbons. After productive work in the laboratory of Advanced Bulk Nanomaterials, I decided to significantly change my research topic and pursue my interest in the rapidly emerging areas of mechanical metamaterials and multimaterial 3D printing at the Technion – Israel Institute of Technology. The Technion postdoctoral fellowship enabled me to carry out high quality research and in particular demonstrate how the mechanical performance of various soft heterogeneous systems can be tailored through the rational design of their internal architecture. I am planning to expand this topic during my research work in FRIAS by designing hierarchical metamaterials capable of undergoing intricate transformations.

FRIAS Project

Instability-driven local pattern transformations for reconfigurable hierarchical mechanical metamaterials

Since unprecedented properties of metamaterials are defined by their involved internal architecture rather than the properties of their constituents, the active control over the structure enables flexible control over the performance of the material. This research project is devoted to creating soft mechanical metamaterials capable of reconfiguring their internal architecture through local elastic buckling. The additional degree of freedom will be introduced into the design space of mechanical metamaterials, allowing the fabrication of the hierarchical materials that can exist in the multiple stable states. Through the active reconfiguration driven by the external mechanical or non-mechanical stimuli, the reversible switches between different states can be achieved. Considering the intrinsic connection between the composite architecture and propagation of the elastic waves, novel design principles will be employed to enable the flexible control over elastic/acoustic waves, therefore providing the fundamentals for the future implementations of such reconfigurable metamaterials in various applications related to vibration isolation.
