Research Interests
Prof. Kougioumtzoglou and his research group develop primarily analytic and numerical methodologies for stochastic response analysis, reliability assessment, and optimization of complex systems and structures in the presence of uncertainties. These methodologies lead eventually to efficient design of dynamic systems ranging from the nano-scale (e.g., nano-mechanical oscillators) to the macro-scale (e.g., energy harvesters and civil infrastructure systems). Specific theoretical research themes include nonlinear stochastic dynamics and path integrals, computational stochastic mechanics, and uncertainty quantification. Nonlinear systems exhibiting time- and space-localized behaviors, described by wavelet- and/or fractional derivative-based operators, receive particular attention. Additional research endeavors with diverse applications in structural, earthquake, marine and wind engineering include uncertainty modeling and propagation based on joint time-frequency signal processing techniques, and on sparse representations theory and tools. Representative cross-disciplinary collaborative work relates to precision medicine applications such as modeling and analysis of the dynamic cerebral autoregulation physiological mechanism.
