Vitaliy completed his MSc in Applied Mathematics and Informatics at Novosibirsk State University in 2008, focusing on parallel iterative methods for solving 3D diffusion-convection boundary value problems. Then he moved to Japan for his internship at Schlumberger to work on tomographic inversion of vertical seismic profile 3D data, with the goal to provide high performance computations. He gained a PhD at the University of Twente in 2014, studying the mechanical and physical behavior of highly polydisperse (in size) granular- and colloidal-like 3D systems, using theory and computer modelling. After that he had some experience of working in industry as a Software Engineer at TomTom, Amsterdam.

In 2014 he joined the CET team in Perth to work on the development and validation a near-real time 3D joint geophysical/geological inversion code, with the goal to apply this parallel code to the inversion of the geology of the 50 million km3 volume beneath Western Australia. This implies the treatment of huge data sets accessing major supercomputing resources and the development of appropriate mathematical algorithms for the targeted machines
