RNDr. Ondřej Krýza, Ph.D. (*1986) has been employed as a researcher in the Dynamics of orogens and rock deformation team since 2017, where he is engaged in analogue and numerical modelling of crustal deformation and heat transfer associated to continental collision systems. Recently he is also part of the Volcanic and magmatic processes team.
During bachelor and master studies, he was interested for the numerical approach and modelling of large-scale geodynamical systems. His combined geology-physics background culminated in the diploma thesis where he was focused on application of multivariate statistical methods for investigation of crustal diapirism based on Rayleigh-Taylor instability evolution.
During the doctoral study at the Charles University, he extended his expertise to analogue techniques and continued also with numerical modelling of the lithosphere-scale deformation and associated heat transfer in the collisional systems. The core of his dissertation represent the models of the oroclinal buckling, detachment folding and crustal inversion induced by gravitational instability. The second part of the thesis is related with the experimental methods in the low-pressure environment and investigation of the potential Martian mudflows.
Current research interests are: a) Dynamics of mantle and crust (convergent zones), b) Detachment/diapiric folding of the lower crust, c) application of the photogrammetry and DIC methods for evaluation of analogue models and physical experiments, d) Numerical methods in geodynamics, e) physics of mud volcanism in low-pressure environments (with applications to the potential mudflows on Mars or Ceres) and f) behavior of the binary salt-water systems in the low-pressure environments (application to cryovolcanism within the Solar system).
