Dr. Rassul Karabalin, Ph. D.

 Dr. Rassul Karabalin is a senior research scientist at the California Institute of Technology. He is an emerging young leader in the field of nonlinear nanoelectromechanical systems. As a member of the Michael Roukes research group, he is exploring NEMS as a tool for studying complex nonlinear behavior in discrete systems. He investigated the physical nature of nonlinear properties in NEMS and developed several methods of controlling nonlinearity. While exploring the dynamics of parametric resonators, he developed NEMS parametric amplifiers, nondegenerate parametric system in strongly interacting nanomechanical devices, and a technique of controlling the bifurcation topology of weakly coupled NEMS resonators. He succeeded at building an array of two strongly interacting highly nonlinear nanomechanical resonators, which led to experimental demonstration of dynamic state transitions and deterministic chaos. He also made significant contributions to the development of piezoelectric depletion-mode NEMS, analysis of nonlinear elasticity in NEMS, and nonlinear self-sustained NEMS oscillators.
