Major Career Accomplishments:
My research to date has focused on nonlinear dynamics in mechanical, electrical, and biological systems. I adapted the Harmonic Balance Parameter Identification (HBID) method to create accurate simulations of a piezoelectric beam energy harvester. The HBID method is readily applied to create models of systems in any energy domain.
My interests in mechanical vibrations have led me to conduct research in stochastic resonance. I have explored stochastic resonance (SR) in mechanical systems both experimentally and through simulations. Potential applications of SR in mechanical systems include both sensors for structural health monitoring and energy harvesters for powering remote sensors. In addition, I have worked with a team of researchers exploring stochastic resonance in bacteria protein.
I am also interested in how time delays affect the stability of systems. As part of my research I have compared several cutting-edge numerical time delay methods. The methods are valuable to systems related to manufacturing, biology, traffic among many other research topics. In particular, my research has led to a new method (based on the spectral element method) of evaluating the extended delayed feedback control of chaos.
