Research Interests
Prof. Kougioumtzoglou and his research group develop primarily analytic and numerical methodologies for stochastic response analysis, reliability assessment, and optimization of complex engineering systems and structures subject to uncertainties. These methodologies lead eventually to robust and 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, fractional calculus modeling, computational stochastic mechanics, uncertainty quantification methodologies, and signal processing techniques. Additional research endeavors with diverse applications in structural, earthquake, marine and biomedical engineering include uncertainty modeling and propagation via joint time-frequency analysis tools such as wavelets, as well as analysis of high-dimensional and/or incomplete data via sparse representations and compressive sampling.
Brief Bio
Prof. Ioannis A. Kougioumtzoglou received his five-year Diploma in Civil Engineering from the National Technical University of Athens (NTUA) in Greece (2007), and his M.Sc. (2009) and Ph.D. (2011) degrees in Civil Engineering from Rice University, TX, USA. He joined Columbia University in 2014, where he is currently an Associate Professor (with tenure) in the Department of Civil Engineering & Engineering Mechanics. Prof. Kougioumtzoglou is an awardee of the Junior Research Prize from the European Association of Structural Dynamics (EASD) for outstanding research in nonlinear stochastic dynamics. He is a recipient of the prestigious CAREER award from the National Science Foundation (NSF), which recognizes early-stage scholars with high levels of promise and excellence, and of the Walter L. Huber Civil Engineering Research Prize from the American Society of Civil Engineers (ASCE) for seminal contributions to the field of stochastic engineering dynamics.
Prof. Kougioumtzoglou has published more than 90 peer-reviewed journal papers. He is an Associate Editor for the ASCE-ASME Journal of Risk and Uncertainty in Engineering Systems and an Editorial Board Member of the following journals: Mechanical Systems and Signal Processing, Probabilistic Engineering Mechanics, and International Journal of Non-Linear Mechanics.
