Ioannis A. Kougioumtzoglou and his research group develop primarily analytic and numerical stochastic methodologies for the response analysis, reliability assessment, and optimization of complex engineering systems and structures under the presence of 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).

Research Interests

Nonlinear stochastic dynamics, computational stochastic mechanics, uncertainty quantification methodologies, signal processing techniques, fractional calculus modeling, energy harvesting, nanomechanics, reliability assessment of complex dynamical 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. 

 

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 in the Department of Civil Engineering & Engineering Mechanics. Prof. Kougioumtzoglou has published more than 120 technical papers in peer-reviewed International Journals and Conference Proceedings, and was chosen in 2018 by the National Science Foundation (NSF) to receive the prestigious CAREER Award, which recognizes early stage scholars with high levels of promise and excellence. He is also the 2014 European Association of Structural Dynamics (EASD) Junior Research Prize recipient “for his innovative influence on the field of nonlinear stochastic dynamics”. Prof. Kougioumtzoglou is an Editorial Board Member of the following Journals: Mechanical Systems and Signal Processing, Probabilistic Engineering Mechanics, and International Journal of Non-Linear Mechanics. He is also a co-Editor of the Encyclopedia of Earthquake Engineering (Springer), an Associate Managing Editor for the ASCE-ASME Journal of Risk and Uncertainty in Engineering Systems, and has served as a Guest Editor for several Special Issues in International Journals. He has held Visiting Professor positions in several universities worldwide, has served in the scientific and/or organizing committees of many international technical conferences, and has co-chaired the 13th International Probabilistic Workshop (IPW 2015). Prof. Kougioumtzoglou is a member of the American Society of Civil Engineers (M.ASCE), while he currently serves as a member of the ASCE Engineering Mechanics Institute (EMI) committees on Dynamics and on Probabilistic Methods. He is a Licensed Professional Civil Engineer in Greece, and a Fellow of the Higher Education Academy (FHEA) in the UK
