Gottlieb, Oded
Professor Emeritus
History Highlights:
- Oded Gottlieb is the Henri Garih Professor of Mechanical Engineering at the Technion – Israel Institute of Technology. He received his BSc (1983) and MSc (1987) from the Technion and his PhD (Ocean Engineering/Applied Math) from Oregon State University (1991). Following a postdoc at MIT (1992) he returned to the Technion (1993) where he founded and directs the Nonlinear and Chaotic Dynamical Systems Research Group. He is the recipient of the AIAA Jefferson Award (1991) and the Technion Award for Innovative Interdisciplinary Research (1999). He served as an Associate Editor of the journal Communications in Nonlinear Science and Numerical Simulations and a Subject Editor in the Journal of Sound and Vibration. The focus of the Gottlieb research group is on chaotic dynamical systems which are unpredictable even without random perturbations that are inherent in nature. Theoretical analysis of these systems include a combined methodology that incorporates both singular perturbation techniques and computational bifurcation continuation where chaotic interactions are governed by sensitivity-to-initial-conditions. Current applications include nano-resonator sensor arrays and fluid-structure-interaction systems where complex spatiotemporal dynamics, chimera states and self-excited system response are governed by global bifurcations.
Research Interests:
- Nonlinear and chaotic dynamical systems, global bifurcations, complexity and spatiotemporal instabilities in continuum mechanics (elastica/beams/plates/shells).
- Stability and control of nonlinear multi-element rigid body systems and nanoresonator arrays, modelling and estimation of mechanical properties from nonlinear dynamical experiments in nano-opto-electro-mechanical systems.
- Fluid-structure interaction, spontaneous otoacoustic emissions (SOE) and irregular self-excited oscillations of the cochlea, vortex-induced vibration (VIV), application of bifurcation theory to ocean engineering systems.
