Biography
Vitaliy is an applied mathematician who holds a PhD degree in Computational Physics. His research interests include design and development of high-performance computational algorithms in application to geophysical inversion, and computational geology. In 2021, Vitaliy joined the Centre for Exploration Targeting to work on the MinEx project Recovery of stratigraphic data from drillhole databases. This project aims to recover stratigraphic information from legacy geological survey drillhole databases. Legacy and new drillhole data are a key constraints for geological understanding and subsequent building of 3D geological models. Company databases held by Australian Geological Surveys often contain complexly coded lithological information, but limited stratigraphic data. This project will develop Open Source algorithms to automate the extraction of lithological and stratigraphic information with associated uncertainty quantification.
